CAG in DNA News

CAGiversary!
well volks...CAG is now linked to our DNA structure:

"Most mutations involve typos: Something bumps a cell’s elbow as it’s copying DNA and the wrong letter appears in a triplet—CAG becomes CCG. In “silent” mutations, no harm is done: Because the DNA code is partly redundant, sometimes the before and after triplets call for the same protein building block (an amino acid). So the net effect is like mistyping “grey” for “gray.” But if CAG and CCG call for different amino acids—a “missense” mutation—the protein can change shape and become disfigured."

watch those DNA elbows!!
