Hereditary information is stored inside the nucleus, which doeshave chromosomes that contain many genes. DNA is an important partof determining who we are.
The number of genes varies. Most of any chromosome consists of non-coding DNA, which does not contain any genes. Each chromosome has many chromatins. One gene consists of many chromatins. Therefore, one chromosome could have many genes.
Haploid number is the chromosome count that is added up to completea set of chromosome of the cell's nucleus. One set of human haploidhas 23 chromosomes.
since each produces 2 as a pair they will each have 26 since they are together and that makes 52
A gene is a specific region of DNA that codes for a particular protein. A chromosome is a long, continuous thread of DNA that consists of numerous genes and regularity information
No - chromosomes contain genes. A chromosome is a long strand of DNA coiled up into the 'X' shape you see in textbooks/under a microscope. A gene is simply a section of DNA that codes for a protein. So a gene is simply a small piece of a chromosome. Sources: undergraduate studies in biology.
same traits the same traits as each other. Different chromosome pairs code for different traits than other chromosome pairs do though. Only homologous chromosomes (chromosome pairs) code for the same trait as each other.
23 from mom 23 from dad = 46 ^^^^^^^^^^^^ This answer is incorrect. The answer above answers the question: How many chromosomes are in the human genome? Chromosomes are made up of genes and in the human body there are 23 pairs of chromosomes, the human genome is theorized to have 20,00…0-25,000 genes So assuming (unrealistically) that every chromosome carried the same amount of genetic material (which they don't), then the answer would be 22,500/23 (for approximations sake).

hundreds and thousands, no one probaly knows for sure. Genes make us what we are from our hair colour to our gender, our insulin production ect.. there are loads
The molecule that contains genes is called DNA or Deoxyribonucleic Acid. This very very long chain molecule is a polymer of structures called Nucleotides which are made up of three parts. All nucleotides have the same pentose sugar called reibose as the central unit. From this sugar projects a phosp…hate group on one side, this too is the same in every nucleotide. The final part of the mucleotide is the "Base". This can be one of 4 molecules Adenine, Thymine, Guanine, Cytosine. The Phosphate of one nucleotide bonds to one of the carbons of the next nucleotides ribose. The phosphate of this next nucleotide then bonds to yet another nucleotides ribose and so on until there is a long chain. From the chain projects different cominations of the bases and the pattern is what maked up genes. As all the bonds are covalant it is one molecule and is called DNA. (MORE)
If we use the word "chromatid", there are always two . (As with twins!) . In a eukaryotic cell immediately after cell division (mitosis or meiosis), each chromosome contains only one DNA molecule. . If the cell is preparing for a subsequent division, then midway through interphase the DNA repli…cates. Now there are two molecules of DNA in each chromosome. . At the start of the following division, in prophase, the chromosomes condense, and the two DNA molecules, with their many associated proteins, become visible under a light microscope as sister-chromatids.

Its either the same traits or DNA. i tried the other 2 and they were wrong. good luck : )
As of April 2003 researchers estimated that building a human would require only about 24,500 genes (the mustard seed plant has about 25,000 and fruit flies about 13,000). When analysis of the draft human genome sequence was published in February 2001, there was estimated to be only about 30,000 to 4…0,000 protein-coding genes. This number will probably fluctuate as applications of the HGP are implemented (MORE)
Nobody knows yet exactly how many genes there are on any human chromosome. Here are some recent figures: . X chromosome 1529 genes (155 million base pairs) Y chromosome 344 genes (57 million base pairs). . However, these should be regarded as approximate while scientists work towards …higher resolution sequencing and more complete interpretation. (MORE)
46 23 from each parent...unless there is a mutation.. Hi sorry to but in, but i was just wondering. If a human zygote contains 46 chromosomes and then total chromosomes they have is 46. Then if a mouse has 40 chromosomes would it's zygote be 40 as well? I have Biology homework and i was just won…dering. Thanks! (MORE)
23. Germ cells (sperm and egg cells) are haploid, which is to say they possess half of the total number of chromosomes found in somatic cells. Somatic cells in humans have two sets of 23 unique chromosomes for a total of 46 chromosomes. .
Technically, the correct answer is no since . However, if you want a bold answer that isn't specific, the answer is yes. the answer depends on how specific you need to be. Chromosomes are made up of DNA and DNA is made up of genes.
Human gametes carry half the genetic information of an individual.. Humans have forty-six chromosomes so a human gamete has twenty-three pairs.
Yes, the y chromosome is critical for survival, for males at least. It contains the DNA (or genes) for the genetic make up of a male's body. No, I don't think so because Y chromosomes just dermine the sex. If it was critical to life then no girl would be alive because they don't have Y chromose. Y c…hromosome truly determines sex. It contains SRY gene that produces TDF which makes sth to male. it not important for survival, just for prodactivity, since Y has came from X chromosome. (MORE)
4 chromosomes 2N means diploid, so the diploid number of the organism is 8. Gametes are haploid cells (N), so they will have half the number of chromosomes as the diploid cell. The diploid cell has 8. 8 divided by 2 is 4..
In humans, body cells (or somatic cells) contain 46 chromosomes in total: 22 pairs of autosomes and 2 sex chromosomes
Genes is what is passed on to child to child. It is commonly referred to as traits. Genes is what makes your looks. For example, if you have a curly hair gene from your father, it means you have curly hair. Obtaining your father's curly hair is random though, it's all genetics really.. Chromosomes …are the bodies on which genes are located that help create and pass down traits. The trait type for males and females are chromosomes, Y and X other than the 44 chromosomes.A male has Y and X and females just have X. (MORE)
Humans have 46 chromosomes (23 pairs), chromosomes are long strands of genes, and since the chromosomes come in pairs, so do the genes. There are 25,000 genes in the entire human genome, and since the haploid chromosome number is 23, there are about 100's of genes on the shorter chromosomes and app…roximately thousands on the longer chromsomes.

No, it's the other way round a chromosome conatins many genes. On humans one can contain anywhere between hundreds or thousands of genes, some are longer than others .. A map of the human genome lives here: http://www.ncbi.nlm.nih.gov/mapview/map_search.cgi?taxid=9606
A chromosome is formed by condensation of large DNA sequences, so yes it can contain hundreds , even thousands of genes indeed
Can each chromosome usually contain multiple genes? yes each chromosome usually contains more than one gene.
They are made from DNA. Genes are short sections of DNA.Genetically identical cells are produced by a type of cell divisioncalled mitosis.
In recent study it has been found that there are about 20,000 to 25,000 genes in our genome. Most of the sequences in our genome does not code for anything. Junk DNA or introns constitute about 90% of our genome.
How many chromosomes are present at anaphase if a cell contains 16 chromosomes at the start of mitosis?
There would be 32.There would be two complete sets of 16, the original amount. In anaphase the cell has split yet, so it is still one cell. It is in telophase that the cell actually split and finds new cells.
What is in all the genetic material contained in an organism including its chromosomes genes and DNA?
Genome : is the entirety of an organism's hereditary information. It is encoded either in DNA or, for Mnay types of virus, in RNA.
It would be very likely that chimpanzees have about as many genes as we humans have, which was found to be about 22 thousand. It could potentially increase, but with our techniques getting better and better, it would not increase very much. For example, it wouldn't increase from the year 2012's numb…ers to 40 thousand in one jump. It'd probably stay near 20-25 thousand. Genes account for about 1% of our total genome. Genes code for proteins. Genome consists of much more than just genes, for example pseudogenes. Genes is a misused term in our media. The reason I say that chimpanzees will have about as many genes as we do is because genes are a more important part of our genome. Changing genes occurs slower over time than the changing of the other parts of the genome because they are more sensitive. That is not to say that the other parts of the genome cannot be as sensitive, just that certain genes especially are more sensitive than other parts. Take for example a bridge. Let's say we built a bridge, but we started with green bricks at the bottom. We then used red bricks at the top of the bridge. If we changed these green bricks at the bottom, it'd probably mess up the entire bridge, whereas if we only messed with the red bricks at the top of the bridge, the infrustructure would not crumble. This is only one of the reasons that some genes are more sensitive than others, and in general more sensitive than some other parts of the genome. I said way too much! -Thomas the bio guy (MORE)
It depends on the chromosome and species. Chromosomes come in different sizes and with different numbers of genes per chromosome. Gene number isn't necessarily dependent on how big the chromosome is, either. Human chromosome 19, for example, is one of the smaller human chromosomes but has the most g…enes. (MORE)
An organism has gametes that contain 18 chromosomes How many chromosomes are in each of its body cells?
Since a somatic cell (body cell) has 2n sets of chromosomes, and a gamete has n sets of chromosomes, then in this case: 18 = n, so 2n = 36. This organism has 36 chromosomes in its somatic cells.
XX=female XY=male the male's second allele determines the sex (gender) of the offspring. If it is a Y, congratulations you're having a boy. If it is an X, you're having a girl. The sex linked genes are always carried along the X chromosome. The female's chromosome is always XX.
Somatic chromosomes. ( remember that the X sex chromosomes of females do not determine sex either. only the SRY region usually found on the Y chromosome determines the male sex. Two XX chromosome and the child is default female. This is not a dichotomy, as variance exists here )
How many chromosomes will be found in the gametes of a gorilla with somatic cells containing 48 chromosomes?
Gametes are haploid -- they have half the number of chromosomes as normal somatic (diploid) cells. Therefore, gorilla gametes will have 24 chromosomes.
E.coli is a single celled organism. Which means it itself is a cell. so either one or none.
That depends on what organism the cell belongs to. A nucleus of a normal human cell contains 46 chromosomes, whereas this is a double chromosome set, i.e. we have 23 pairs of chromosomes that are used for the same functions. Two chromosomes that fulfill the same functions are called homologous. … In human germ cells (sperm and egg cells), the set is halved so that only one chromosome for every function remains. This leaves them with 23 chromosomes. Other organisms have different numbers of chromosomes. For example, elephants have 56 chromosomes in normal cells, guinea pigs even have 64. Maize cells contain only 20. (MORE)
DNA does not contain any chromosomes. Chromosomes contain DNA, and in humans, there are 46 chromosomes in each cell.
No because a single gene is made up of many bases in a row in achromosome that may contain anywhere from several hundred to amillion or more nitrogen bases.
Its the other way around. We have 46 chromosomes in each of our cells. The number of genes per chromosome varies between 500 and 4,000, with a total of about 32,000 genes in the 46 chromosomes.
Sex chromosomes are either x or y. The female can only give off xx's, the male however can give x or y. Therefore the male determines the sex of the baby. Its on the 32 chromosome. :)
Why would Y chromosome be unlikely to contain any of the genes that are absolutely necessary for survival?
The Y chromosome does not contain genes that are critical for human survival because it carries only the genes necessary for determining the sex of the child (specifically that of a male.) It does little else than direct the development of male traits. So, although it is necessary for reproduction, …organisms born without Y chromosomes have the possibility of survival, while those born without X chromosomes have no possibility of survival. (MORE)
If you're a mammal, the key gene that initiates gonad development into testes (the Sry gene) is located on the Y chromosome. However, be aware that while gene necessary for the initiation of the male developmental program is located on the Y chromosome, many genes absolutely essential for complete t…estes and male development are distributed across many other chromosomes.

Sorry - there's just no easy answer there. Some chromosomes are enormous and carry many genes, others are puny and contain very few genes. And chromosomes also differ in what proportion of their DNA is actually coding DNA. To give you a sense of the range, according to ensembl.org (a great genome br…owser website) human chromosome 1 is 250Mb and contains about 2,000 genes (a density of about 8 genes per Mb) and chromosome Y is about 60Mb and contains only about 50 genes (or a density of 0.83 genes per Mb). And that's just within a single species. (MORE)
In humans, there would be a total of 92 chromosomes, 4 sets of 23. During anaphase they separate into opposite poles of the cell, with 2 sets of 23 going to each pole.
Each chromosome has one copy of it's alleles at each gene locus. The matching homolog of that chromosome has one copy of it's alleles at each gene locus.
Every single cell, regardless of being human or not, contains chromosomes, but only when dividing or reproducing. It cells' normal state, their DNA is not wound up in chromosomes, but freely floating around the nucleus.
Why does the Y chromosome be unlikely to contain any of the genes that are absolutely necessary for survival?
Women don't have a "Y" chromosome; the have two "X" chromosomes in that strand of DNA. Men have one X and one Y chromosome.
Genes are stretches of DNA that contain code to make proteins.Chromosomes are made up of numerous Genes.
