The amino acids in the original partial sequence (N-term-...V-G-E-N-E-S...-C-term) have little to no impact on protein structure and function, with the exception of serine. Phosphorylation of the serine residue is required for normal function of the protein. Given this information, which reversion mutation(s) in the gene would restore the normal function of the entire protein? Select the four correct answers. Deletion of 5 base-pairs in the region of the valine codon
Insertion of 4 base-pairs in the region of the valine codon
Deletion of 1 base-pair in the region of the valine codon
Deletion of 2 base-pairs in the region of the valine codon
Insertion of 2 base-pairs in the region of the valine codon
Insertion of 1 base-pair in the region of the valine codon
