Answer:
1. The Mc1r gene codes for the melanocortin 1 receptor (MC1R) protein.
2.Each of the amino acids has a corresponding mRNA codon and DNA triplet consisting of a three-base sequence. A
protein that has 317 amino acids therefore has a DNA base sequence consisting of 951 base pairs (317 × 3 = 951
base pairs). The three additional base pairs correspond to a stop codon for which there is no complementary
amino acid. The stop codon signals the termination of translation.
