1) A protein is 300 amino acids long. Which of the following could be the number of nucleotides in the section of DNA that codes for this protein? (Remember: DNA is double-stranded.) E) 1800 2) A short segment of an mRNA molecule is shown below. The polypeptide it codes for is also shown: 5′-AUGGUGCUGAAG : methionine-valine-leucine-lysine Assume that a mutation in the DNA occurs so that the fourth base (counting from the 5′ end) of the messenger RNA now reads A rather than G. What seq...
