A messenger RNA (mRNA) does more than provide ribosomes a template for creating a sequence of amino acids. It also conveys regulatory information, including so-called stop codons. But just as cars ...
The beauty of the DNA code is that organisms interpret it unambiguously. Each three-letter nucleotide sequence, or codon, in a gene codes for a unique amino acid that's added to a chain of amino acids ...
The genetic code is a set of instructions that direct the translation of DNA into 20 amino acids, the basic units of proteins in living cells. The genetic code is made up of codons, which are ...
