The classes you'll need to take earn an associate's degree will vary depending on the type of program in which you've enrolled.

Start codon. The start codon is the first codon of a messenger RNA (mRNA) transcript translated by a ribosome. The start codon always codes for methionine in eukaryotes and a modified Met (fMet) in prokaryotes. The most common start codon is AUG.
Individual codons code for specific amino acids. A gene is a sequence of nucleotides along a DNA strand-with 'start' and 'stop' codons and other regulatory elements-that specifies a sequence of amino acids that are linked together to form a protein.
