Chromosomes

Parent Category: Genetics
Chromosomes contain the genetic material DNA
Storage location of DNA, and are used to pass on genetic traits.
The DNA of prokaryotes floats around in the cytoplasm of the cell.
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...
Actually the genes on a chromosome closest to the telomeres are themost unstable because they can unravel.
Actually a chromosome consists of many genes/alleles and is neitherrecessive or dominant in and of itself.
Individuals with additional chromosomes beyond the normal 2Ncomplement are generally nonviable and the few exceptions thatresult in a live offspring are still profoundly affected in anegative way. he presence of additional sex chromosomes often haveless profound effects.
Fewer than the normal 2N complement of chromosomes invariablyresults in nonviable offspring. The presence of only one X chromosome results in an infertilefemale.
They help fold and coil DNA to make it smaller.
There are 46 chromosomes in a human Karyotype.
The Y chromosome contains genes for "maleness". It produces malesex hormones and while the fetus is developing, it producesdirection for the formation of male parts.
You would have no variety in the organism.
It varies. Some are much longer and have more genes than others.
The genetically inherited characters are controlled by the genespresent on the chromosomes.
69 haha just kidding
a set chromosome define about progeny which could be male or female
Alleles on the X chromosome as well as chromosome 7 can affect thequality of color vision to varying degrees. This information isbased on very limited research of color deficiency sites on line.
Because x-chromosome has several genes on it whereas y-chromosomehas very few.
Chromosome align at the center at metaphase stage.
No-one knows. We can't see its genetic material because it's tooold.
Mutations in the LMNA gene cause Hutchinson-Gilford progeriasyndrome. The LMNA gene is located on the long (q) arm ofchromosome 1 at position 22.
I am aware of three genetic disorders involving extra chromosomes. I know of none involving less chromosomes.
each chromosome has thousands of genes that play an important role in determining how an organism develops and functions
synapsis is a pair of homologs that pair together
Chromosomes carry genetic material from generation to generationand help in evolution of better adapted organisms, hence these areimportant for each organism.
Since there are two X chromosomes in most female animals one of thetwo becomes an inactive Barry body to facilitate proper cellfunction. in some animals the inactivation is random in others theX chromosome provided by the male is always inactivated.
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.
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...
Diploid to haploid, or 2n to n chromosomes. So it cuts in half, an allele from each homologous pair of chromosomes.
Chromosomes form during Prophase of Mitosis.
Chromatins are made up of DNA, RNA and nuclear proteins. DNA andRNA are nucleic acids inside the cell. When a cell is going todivide the chromatins condense together to form chromosomes.
No. The only difference is the sex determining chromosome. Males have XY and females have XX. It is the sperm that determine whether a baby will be male or female. Eggs only provide X chromosomes. So down through history, it has always been an injustice that women were blamed for not providing a son...
Since the traits for hemophilia are carried on the X chromosome andnot the Y, it is more probable for females to have a chromosomewith the mutation. Since the mutation is considered recessive andmales only have one X chromosome, they are more likely to portraythe phenotype for hemophilia than their...
It varies from species to species
They are not obsolete. Y chromosomes are what make males. When a child is conceived, they get two chromosomes: one from their mother, and one from their father. Since all women have two X chromosomes, the child gets an X from their mother. The father can give the child either an X or Y chromosome...
There is no change in chromosome number. Just in the amount of chromatids. Because during synthesis each chromosome doubles and becomes sister chromatids.
During interphase, chromosomes are in the form of thread-like structures called chromatin.
Both parents will give a girl an X chromosome. The father will givea Y and the mother will give an X to a boy.
Humans have thousands of different genes arranged on 23 pairs of chromosomes. These are arranged from largest to smallest on a karyotype. Uh, hi I read your answer, and I think you misspelled a word. -anonymous.
Chromosomes are (usually) X-shaped and consist of condensed DNA (chromatin) coiled around proteins called histones like yarn around a spool.
Chromosomes contain DNA that provides a "blueprint," or genetic information, for the organism.
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,...
Y dont we know how many chromosomes does a bat have? we should know this for my class i mean come on 4realz u are not helping find this answer Cola33: A bat has 8 choromosomes, which means that she/he has 4 pairs of chromosomes, I'm pretty sure. Y dont we know how many chromosomes does a bat...
chromosomes are DNA + associated proteins.treatment with proteases and one can obtain DNA
if a cat has 38 chromosomes in each of its body celss, how manychromosomes will be in each daughter cell after mitosis?
How many chromosomes are in the sex cells of a earthworm? 36
A chromosome is always bigger. Chromosomes are made up of genes, all chromosomes carry different genes. There are 46 total chromosomes in our body, 23 pairs, and about 35,000 genes so it makes since that genes are essentially microscopic to the size of a chromosome.
R is a dominant allele for trait 'r' and r is a recessive allele for trait 'r'.
In animals with XY sex chromosomes the allele for the trait is onthe X chromosome.
Approximately FORTY CENTIMETERS 40 CM
mate and pairs up
The chromosome of a bacterium does essentially the same thing that chromosomes do for all life forms. It describes the formation of proteins for the organism, allowing it to produce and grow the proper structures at the proper time, allowing it to survive most efficiently.
Genes determine the specific characteristics of an organism.
They are made of DNA
Two sister chromatids make one chromosome.
34, see related link for zoological data and genetics.
No cystic fibrosis is caused by a mutated CFTR gene.
sludge worm , or sewage worm has 36 chromosomes(diploid)number
Bacterial genomes are termed as chromatid in contrast to complexchromosome structures of eukaryotes
Yes, Chromosomes are amde up of Genes. I just found this out for homework.
The phenomenon of occurrence of multiple chromosomes in plants isknown as polyploidy. The very basic cause of multiple chromosome formation is relatedwith inhibition of spindle formation during mitosis. Other causeare due to hybridization etc.
yes chromosomes are found in the nucleus cell
we have 46 chromosomes in Mitosis during interphase when the DNA doubles, but really Humans have 23 chromosomes. Meiosis is reproduction and goes through Mitosis twice but skips interphase the second time and creates gametes(sex cells) -Marina20 .
The only difference in the chromosome is the presence of the allelethat results in an individual with acondroplastic dwarfism. Thechromosome affects the structure of the organism, the alleleaffects the growth plates of the long bones resulting shortenedlimbs.
In the nucleus of a cell along the equator.
Chromosomes are the same no matter what gender you are, or what species, all cells have them. It is the information contained within those chromosomes that is different between cells.
They are colorless
