WebA single can code for more than one protein, and they can also only code for a precursor to a protein. I do believe that with alternative splicing only one type of the protein is made in a single cell. Alternative splicing allows for other, differently differentiated cells to have different versions of a protein. WebOne of the definitions of a gene is as follows: a segment of deoxyribonucleic acid (DNA) carrying the code for a specific polypeptide. Each molecule of messenger RNA (mRNA) is a transcribed copy of a gene that is used by a cell for synthesizing a polypeptide chain. If a protein contains two or more different polypeptide chains, each chain is coded by a …

Since most of a cell’s DNA is in the nucleus, the “recipe” stored in that gene must leave the cell’s nucleus in order to be turned into a protein. To do that, the “recipe” is copied by a molecule called messenger RNA (mRNA).
