Final answer:
There are 64 possible combinations of bases on an anticodon. The anticodon is a sequence of three nucleotide bases found on transfer RNA (tRNA) molecules that binds to a complementary codon on messenger RNA (mRNA) during protein synthesis.
Step-by-step explanation:
There are a total of 64 possible combinations of bases on an anticodon. The anticodon is a sequence of three nucleotide bases found on transfer RNA (tRNA) molecules that binds to a complementary codon on messenger RNA (mRNA) during protein synthesis. The anticodon can base pair with one of the 64 codons formed by multiple combinations of the nucleotide bases A, U, G, and C.
