Where Can I Find Nucleotide Chains for Genes and Chromosomes?

In summary, the conversation discusses the difficulty in finding a source for the nucleotide chain of a specific gene, Mxra8, and the request for help in locating this information. The National Center for Biotechnology Information is suggested as a resource for finding gene and gene sequence information, with an example given for Mxra8. A link to the genomic and coding sequences for Mxra8 can be found on the NCBI's page, as well as access to the human genome sequence on the website.

I can find where a gene is usually on a particular chromosome - e.g. Chromosome 1 Mxra8 - but I can not take Mxra8 and find a source for its nucleotide chain. Help here would be appreciated. Would also appreciate if there is any source for the sequence of total bases per chromosome - e.g. the entire nucleotide chain for a chromosome. Would be some long strings but it has to be out there somewhere.

A good resource to search for information about genes and gene sequences is the National Center for Biotechnology Information (http://www.ncbi.nlm.nih.gov/)

For example, here is the NCBI's page for Mxra8: http://www.ncbi.nlm.nih.gov/gene/54587

A link to the genomic and coding sequences can be found near the bottom of the page: http://www.ncbi.nlm.nih.gov/gene/54587#reference-sequences

You can access the human genome sequence at NCBI as well: http://www.ncbi.nlm.nih.gov/assembly/GCF_000001405.26/

1. What is a nucleotide chain?

A nucleotide chain is a long sequence of nucleotides, which are the building blocks of DNA. Nucleotides consist of a sugar, a phosphate group, and a nitrogenous base, and are arranged in a specific order to form a nucleotide chain.

2. What is the role of nucleotide chains in genes?

Nucleotide chains make up the genetic code of an organism and are responsible for storing and transmitting genetic information. They contain instructions for the production of proteins and determine an organism's physical traits.

3. How is the sequence of nucleotide chains determined?

The sequence of nucleotide chains is determined by the sequence of bases in DNA. Adenine (A), thymine (T), guanine (G), and cytosine (C) are the four bases that make up the genetic code. The specific arrangement of these bases determines the sequence of nucleotide chains.

4. Can the sequence of nucleotide chains change?

Yes, the sequence of nucleotide chains can change through mutations. A mutation is a random change in the genetic code that can result in different amino acids being produced, which can ultimately lead to changes in an organism's traits.

5. How do nucleotide chains contribute to genetic diversity?

The sequence of nucleotide chains is unique to each individual, which contributes to genetic diversity. This diversity allows for variations in physical traits and can also impact an organism's ability to adapt to changing environments.
