Answer to Question #60283 in Genetics for Candy

Question #60283
Does each protein contain all 20 amino acids? What happens to mRNA and tRNA after the polypeptide chain is formed? “Having more than one possible code for an amino acid is called redundancy or degeneracy of the code. It acts to buffer the effect of mutations because a change to a single base may not necessarily change the amino acid coded for.” - Since there is a change in the base sequence but the amino acid is still the same, is this called a same sense mutation? Do all genes start and end with the triplets complementary to the start and stop codons? “AUG is the start signal. It codes for the amino acid methionine. This amino acid is usually cleaved off the completed polypeptide chain.” - So the amino acid methionine is hardly part of a protein since it is cleaved off? Do mutations occur on the template strand or coding strand of DNA?
