If you have a dna sequence that codes for a protein and is 105 nucleotides long. a framshift mutation occurs at the base - how many amino acids will be correct in this protein? a. 36 amino acids. b. 28 amino acids. c. 15 amino acids. d. 8 amino acids.

28 amino acids

Explanation:

When you have a frameshift mutation means that the protein will no longer be complete due to a signal of stop or another start signal in the sequence. The protein will not be the same as before the mutation occurs. If a sequence is 105 nucleotides long means that the amino acids that comprise the protein are 35 (each amino acid comes from a combination of 3 nucleotides, 105/3=35). When a mutation occurs in 85th base there are 20 bases that do not work well or that will not be correct (105-85=20). So, when you don't take into account those 20 bases, the sequence will be correct until 84th base pair, and, as the amino acids come from a mix of 3 bases 84/3=28.
