Illustrate how differences between the structure of dna and rna are reflected in the ways that proteins interact with them 6 genes have been defined in many different ways over the years. Translation of the dna/rna code into a sequence of amino-acids is just the beginning of the process of protein synthesis the exact sequence of amino-acids in a polypeptide chain is the primary. It strengthens the specific pairing of the dna bases: thymine to adenine, guanine to cytosine by proofreading and deleting mismatched bases trna, rrna, and mrna although the dna holds the genetic code, the rna transforms this genetic information into the synthesis of proteins.
