DNA follows instructions with switching
(Facts About Evolution)
bacteria, for example, Jacob and Monod demonstrated a control system that operates by switching off 'repressor' molecules, i.e., unmasking DNA at the correct 'line number' to read off the correct (polypeptide) subroutines. With eukaryotes \a common type of bacteria\, Britten and Davidson have ...

The Amazing Story of Messenger RNA
(Facts About Evolution)
code in the gene (which is DNA, of course) is used to construct a messenger RNA molecule in which is encoded the message necessary to determine the specific amino acid sequence of the protein. "The cell must synthesize the subunits (nucleotides) for the RNA (after first synthesizing the subunits ...

Neutral mutation
(Facts About Biology)
neutral mutation is a mutation that occurs in an amino acid codon (presumably within an mRNA molecule) which results in the use of a different, but chemically similar, amino acid. This is similar to a silent mutation, where a codon mutation may encode the same ...
