acids<br />

Thous<strong>and</strong>s <strong>of</strong> different proteins exist, each with its<br />
own function (enzymes, etc.).<br />
Each protein is manufactured in the cell using a code<br />
contained in the DNA. DNA<br />
• The code for the 20 essential amino acids consists <strong>of</strong> at least a 3-base set<br />
(triplet) <strong>of</strong> the 4 bases<br />
• If one considers the possibilities <strong>of</strong> arranging four things 3 at a time<br />
(4X4X4), we get 64 possible code words, or codons (a 3-base sequence<br />
on the mRNA that codes for either a specific amino acid or a control<br />
sequence).<br />
