What percent of the DNA in your chromosomes functions as genes?
Chromosomes contain hundreds to thousands of genes in one very long strand of DNA. The DNA is coiled around proteins called histones. The DNA seems to form a bigger (of course on a very tiny level) part of the chromosome than the histones. Since DNA is comprised of genes, that means that over half of the chromosome is genes. The exact amount would depend on the chromosome.
Which chromosomes carries the fewest numbers of genes?
The y chromosome, which only contains a few hundred genes.
The Y chromosome is larger and carries fewer genes than the X chromosome?
No. The Y chromosome is much smaller than the X chromosome. There are only about 70 active genes on the Y chromosome and many more deleteriously mutated one. The X chromosome contains many more active genes and only crosses over marginally with the Y chromosome.
Which types of mutation can be add genes to a chromosome?
A deletion mutation can take genes away from a chromosome.
How many genes do chromosomes have?
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
Is a chromosome larger than a gene?
There are 25,000 human genes on 23 chromosomes. There are hundreds of genes on the smaller chromosomes and thousands on the bigger ones.
What is the relationship between the genes and chromosomes?
There are thousands of genes in a chromosome.
Does a gene contain hundreds of chromosomes?
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
What do you call the rod-shaped structure that contains hundreds of genes?
Chromosome
What genes are DNA and chromosomes?
DNA is a large, polymeric biomolecule composed of four different types of subunits called nucleotides. The sequence of nucleotides within the DNA molecule can encode information. All the information necessary to encode a protein is called a gene. DNA molecules can be extremely long - extending for millions of nucleotides. A chromosome is a single DNA molecule (encoding thousands of genes) plus associated proteins that provide structure and play key roles in the regulations of genes.
Does an entire chromosome code for only one gene?
You have about 20,000 to 25,000 genes in 23 chromosomes in human cell. So approximately 1000 genes are there in any single chromosome. The gene will be too big in size, if you have one single gene in any single chromosome.

Do prokaryotes have genes?
Yes, prokaryotes have genes. Genes are segments of DNA that contain the instructions for making a protein or RNA molecule. Prokaryotes have a circular chromosome that contains genes, along with additional genetic material in plasmids.
What are the alleles of a gene?
That depends on the gene: some genes have only a few alleles, some genes have hundreds or even thousands of alleles.
What is the name of genes that are carried on the same chromosome?
The genes that are carried on the same chromosome are called as the linked genes.
What do the bands on chromosomes signify?
The bands on chromosomes are chunks of DNA that stain differently. Depending on the section of the chromosome, there may be hundreds of genes or very few genes in each band.
Does linkage refer to how the acids in DNA are connected?
Linkage is called gene linkage .It refers to linking up of genes in a chromosome .It was first properly explained by T.H. Morgan . As there are thousands of genes but number of chromosomes are limited hence each chromosome contains a large number of linked genes .
