DURING ANAPHASE, THE CHROMOSOMES SPLIT IN TWO AND GO TO OPPOSITE SIDES OF THE CELL.
A chromosome is a threadlike strand of DNA in the cell nucleus that carries the genes in a linear order. It is also known as tightly wound DNA. It is a structure that DNA wraps around. MORE INFORMATION: A chromosome is an organized structure of DNA and protein that is found in cells. It is …a single piece of coiled DNA containing many genes, regulatory elements and other nucleotide sequences. Chromosomes also contain DNA-bound proteins, which serve to package the DNA and control its functions. Chromosomes vary widely between different organisms. The DNA molecule may be circular or linear, and can be composed of 10,000 to 1,000,000,000 nucleotides in a long chain. Cells may contain more than one type of chromosome; for example, mitochondria in most eukaryotes and chloroplasts in plants have their own small chromosomes. Chromosomes are the essential unit for cellular division and must be replicated, divided, and passed successfully to their daughter cells so as to ensure the genetic diversity and survival of their progeny. Chromosomal recombination plays a vital role in genetic diversity. If these structures are manipulated incorrectly, through processes known as chromosomal instability and translocation, the cell may undergo mitotic catastrophe and die, or it may aberrantly evade apoptosis leading to the progression of cancer. In practice "chromosome" is a rather loosely defined term. In prokaryotes and viruses, the term genophore is more appropriate when no chromatin is present. However, a large body of work uses the term chromosome regardless of chromatin content. The simplest genophores are found in viruses: these DNA or RNA molecules are short linear or circular genophores that often lack structural proteins. Chromosomal DNA encodes most or all of an organism's genetic information; some species also contain plasmids or other extrachromosomal genetic elements. Structure in nucleus made of DNA and protein.

A chromosome is an 'X' shaped gene which contains DNA, found inside living cells. Chromosomes are easily seen using a microscope and are normally invisible most of the time (this period of time called 'interphase') but become visible when the cell starts to multiply.
The small bodies in the nucleus of a cell that carry the chemical"instructions" for reproduction of the cell. They consist ofstrands of DNA wrapped in a helix around a core of proteinChromosomes are thread-like structures that are found in thenucleus of a cell.
Basically is genetic info. Different organisms have different types of chromosomes. In bacteria (prokaryotic cells) a chromosome consists of a loop of DNA; it has no end. Along the length of the DNA are segments called genes, which contain information that the cell uses for growth and devel…opment. Most bacteria have only one chromosome, but some have more (the cholera organism Vibrio cholerae has two). In eukaryotic cells, chromosomes are linear (they have two ends). The DNA is associated with proteins called histones. There is always more than one chromosome in a eukaryotic cell. After cell division and before DNA replication, there is only one molecule of DNA in each chromosome. After DNA replication, there are two DNA molecules in each chromosome; these are separated at the next cell division. In higher organisms, including humans, genes make up only part of the DNA.. * . A chromosome is a single large macromolecule of DNA, and constitutes a physically organized form of DNA in a cell. It is a very long, continuous piece of DNA.. * . A chromosome refers to the colored thread observed localized within the nucleus. It is the genetic information carrier, and it may be extended (in interphase) or highly condensed (during mitosis or meiosis).. The number of chromosomes is species-specific and if any alteration occurs it leads to disease condition or move forward towards evolution. In humans the total number of chromosomes is 46 or 23 pairs; mouse has 44 or 22 pairs; Onion - 16 or 8 pairs; Drosophila - 8 or 4 pairs. A chromosome after DNA replication has a pair of threads called chromatids held together by a primary constriction called a centromere. Chromatids consists of supersolenoid and scaffold structure followed by solenoid structure. Solenoid structure is formed by compaction of polynucleotides bound by histones and non-histone proteins. It leads to a fundamental structure called a nucleosome which consists of a nucleic acid part and a protein part. The protein part consists of positively-charged histones rich in lysine, arginine, and glycine. Histones consists of core subunit made of octamer made of 2 copies of H2A, H2B, H3 and H4. Linker histone H1 connects 2 nucleosomes.. Chromosomes are classified based on various criteria:. 1) The chromosomes which are common to both males and females are referred to as autosomes or body chromosomes and the chromosomes which determine the sex of an organism are called sex chromosome or allosomes (look dissimilar). In humans we have 22 pairs of autosomes and 1 pair of sex chromosomes (X and Y chromosomes).. 2) Classified based on the position of centromere or primary constriction. The either sides of the centromere is referred to as arms (p- petite or short arm; q - quadran or long arm). When p=q (V shaped) - metacentric chromosome; When p ( Full Answer )
They carry the tens of thousands of traits that are inside you to make you look like who you are. During sexual reproduction your Parents give you half of each of their Genome; which are copies of theirs. Some of the traits may be dominant, which shows [are expressed] over the recessive traits…. Chromosomes have genes on them, which are passed down from a parental generation to their progeny. ( Full Answer )
A chromosome is determined to be metacentric, acrocentric or telocentric by the location of its centromere. Centromeres are the point of attachment of two sister chromatids. Sister chromatids are formed during DNA replication prior to mitosis or meiosis. Chromosome Y by itself (when it is not replic…ating and there are no sister chromatids) is not acrocentric, as it wouldn't even have a centromere location. ( Full Answer )

I am aware of three genetic disorders involving extra chromosomes. I know of none involving less chromosomes.
Chromosomes are visible during prophase. Chromosomes are onlyvisible in cells during the cell division because the DNA andprotein that the chromosomes are made of are spread throughout thenucleus.
Chromosomes are rod-shaped structures usually found in pairs in the nucleus of a cell. They contain information determining characteristics of an organism when it is reproduced.

Plants have also know to have multiple chromosome doublings - that is sudden creation of species which have 2 3 or even 4 times the proper number of chromosome in their cells. The most notable example of this i…s wheat. ( Full Answer )
Chromosomes are the rod-shaped, filamentous bodies present in the nucleus, which become visible during cell division. They are the carriers of the gene or unit of heredity. Chromosome are not visible in active nucleus due to their high water content, but are clearly seen during cell division.
It's found in the nucleus of almost all living sells and it carries genetic information also known as DNA which basically works out how your body is to function and grow.

In order to increase genetic diversity, so that children cells are not identical to parent cells.
you have 2 sets of chromosomes and you get one set from your mother and one from you father. they're made of nucleic acids
Everyone has 46 chromosomes, half from their mom and half from their dad. So, when a male and female reproduce together they each contribute the same number of chromosomes, 23 so then their baby will have 46.
Chromosomes carry genes (genes are short lengths of chromosomes) there are 23 pairs of chromosomes and they each contain alleles (different copies of the same gene) in the same place on each chromomsome.
In the nucleus of each cell, the DNA molecule is packaged intothread-like structures called chromosomes.
The purpose of chromosomes in the nucleus of a cell is to contain genetic information that tells the cell what to do, how to behave etc. Chromosomes also contain the information that determines what you look like; whether you have brown hair, blue eyes etc.
Chromosomes that aren't sex chromosomes are called autosomes.There are 44 autosomes in a normal human somatic cell and 22 innormal human gametes. . The only chromosomes that affect the sex of an organism is the Xand/or Y chromosome. XX = Female and XY = Male.
Answer 1 Question is its own answer, like the sound of one hand clapping. Answer 2 The purpose for having purpose is so that goals can be achieved in a directed manner. If an object's purpose is unknown, it cannot be effectively used. For example, a computer has the purpose of being an interf…ace device to communicate and discuss information (among many other purposes). However, someone who does not know this may use the computer as a large hammer since it is a metal object. This is neither the most efficient way to use the computer nor is it the mot efficient way to hammer a nail. Not knowing the purpose of the computer or the purpose of the nail severely hinders a person from achieving their intended goals. ( Full Answer )
Chromosomes are located in the nuclei (singlular form: nucleus) of each cell in your body.
To store genetic information. Each cell in our bodies has over six feet of DNA. If that was all crumpled up and thrown in the cell, it would create a jumbled mess. Chromosomes contain spirals of compacted DNA neatly packaged and easily accessible by the cell. When a specific piece of data is needed…, the correct segment of the chromosome unravels to reveal perfect genetic code, ready to be used. ( Full Answer )
After DNA replication, there are double the number of chromosomes, which will be divided into two identical daughter nuclei during mitosis. For example, a normal human body cell has 46 chromosomes. When it undergoes DNA replication, the chromosomes are doubled so that there will be 92 chromosome…s, consisting of 46 pairs of sister chromatids. During mitosis, the sister chromatids separate into two identical daughter nuclei, each having 46 chromosomes. ( Full Answer )
in a homologous chromosome there are two chromosomes ( a chromosome and a sister chromosome)
The X and Y chromosomes of the [Sex] Chromosome 23 [pair] - when two X gametes mate a female is created and when one X gamete combines with one Y gamete a male is formed.
chromosomes are the carriers of genetic information they are constant in number in all body cells according to the species (humans,and differs between animals themselves) there number is 46 in humans organized in pairs (23 pairs) the first 22 pairs are called autosomes and the last pair is the gonos…omes which indicate the gender of the person if it is XX it is a female but is it is XY it is a male.The X chromosome can carry a genetic data but Y cant.The ova and sperm are the only body cells that have 23 chromosemes in single so that after their union there'll be a complete number of chromosomes.Maybe when you see the answer you'll regret that u asked it :P ( Full Answer )
All humans have 46 chromosomes (23 pairs). in the nucleus of every single cell in our body, excluding the red blood cell which has no nucleus. Each pair of chromosomes has certain genetic coding (one set from each parent). Without these chromosomes sperm and eggs wouldn't know what to do in order …to form a baby. And if my some miracle they did, that baby's cells wouldn't know what their job is, so just wouldn't function. Therefore our skin cells wouldn't exists, neither would our bone cells, etc. So we would just stay as a blob of stem cells (only stem cells which can't change into anything else). ( Full Answer )
Chromosomes are (usually) X-shaped and consist of condensed DNA (chromatin) coiled around proteins called histones like yarn around a spool.
Guevodoces have the usual XY male chromosomes. The apparent lack of male genitalia at birth is due to a hormonal deficiency that causes a reduced response to testosterone during fetal sexual development. As a result, the baby boy has small and ambiguous genitalia until sex hormones surge at puberty,… causing the external genitalia to develop. ( Full Answer )
You have pair of X chromosomes in case of females. You have a pair of X and Y chromosomes in case of male.
it explains occurrence of organelles like chloroplasts and mitochondria but not the enveloping of genetic material in the nucleus
There really is no chromosome disorder, only if the subject has two Y chromosomes or has one X chromosome or one Y chromosome. Then the pairs will not match up and cause disorders such as down syndrome.
A circular chromosome is, essentially, exactly what it sounds like: a chromosome (strand of DNA that carries the genetic information of an organism) that is circular. Circular chromosomes are found in prokaryotes such as bacteria, as well as in mitochondria and chloroplasts. Eukaryotic cells, on the… other hand, typically have chromosomes that are linear, meaning they have two ends that do not connect. ( Full Answer )
A chromosome is something found in the nucleus of every living cell. Chromosomes contain DNA, Which is literally a strand of genetic information, that determines who you are, E.G- Eye colour and hair colour are usually genetic. You can't really have an example of a chromosome, because a chromosome i…s just a general, common chromosome, everyone has them. Also, they usually come in pairs, one from your father, and the other, your mother. ( Full Answer )
Chromosomes are inherited from parents - in sexually reproducing organisms, such as humans - half of the chromosomes come from each parent. You get chromosomes from nucleus of the cell.
Out of 23 chromosome pairs (46 chromosomes in the human cell) 22 pairs are of autosomes and one pair of sex chromosomes. The sex chromosomes are named XX in female and XY in the male persons.
Well there is actually several. There is XXY, Klinefelter: XYY, "Super male": XXX, perfectly normal but still a abnormality: and XO or Turner syndrome, sterile female, small stature, normal intelligence. These are the most well documented but I am sure there is more out there.
It is both. All chromosomes that are not sex-chromosomes (X or Y) are known as autosomes.
Out of 23 chromosome pairs one is the 'sex-linked' chromosome pair. The Answer is 1-out-of-23.
That would be the chromosome number 23. Regarding the [sex] chromosome number 23, the female gametes always have a [haploid] X chromatid, whereas the male gametes are just as likely to possess a [haploid] X chromatid as they are to possess a [haploid] Y chromatid.
What is the purpose of meiosis with respect to chromosome number of parent cells and daughter cells?
Number of chromosomes is reduced to one half in gametes so that when gametes fuse to form zygote original diploid number is restored .
Chromosome is having more than one X gene. Having more than one Xchromosome cause down syndrome.
Genes are stretches of DNA that contain code to make proteins.Chromosomes are made up of numerous Genes.
