WebA gene is a base sequence of DNA that codes for the amino acid sequence of a polypeptide or a functional RNA molecule. Functional RNA molecules are required for protein synthesis. mRNA - the base sequences on messenger RNA molecules are used by ribosomes to form polypeptide chains. tRNA - amino acids are carried to the ribosome by transfer RNA ...

In these chromosomes are areas called genes that code for specific proteins. All the different chromosomes of an organism make up that organism's genome. In other words: DNA makes up genes, genes make up chromosomes, and chromosomes make up a genome. dictionary\u0027s 0c
