Consider the consequences of a mutation in the dna template sequence 5'atg3' to 5'ttg3': what is (a) the resulting change in the mrna codon and (b) the effect on the corresponding amino acid? see section 16.4 (page 344) .

A) The resulting changes in mRNA codon would be;
 CAU TO CAA; This because in the mRNA the base Thyamine is replaced by cytocine, therefore A would pair with Cytosine.

B) The effect on the corresponding amino acid would be a change from His to Gln. This mutation would result to a change form Histidine to Glutamine; this is because the codon CAU codes for Histidine while CAA codes for Glutamine.

Giga is the second highest prefix on the normal scale, the first is terra.
