Because codons are triplicates, there are ______ possible nucleotides combinations that could make a codon; each giving rise to one specific amino acid. Yet, there are only 20 amino acids used to produce proteins. Thsus, the gentic code is said to be _______.

I. 16, unambigous
II. 64, universal
III. 12, degenerative
IV. 64, degenerative

I strongly believe that the answer is "II" becaues I think the genetic code is universal i.e. codons that code for amino acids will be same in bacteria, plants and animals so it is possible to give bacteria the genetic sequence to make insulin and the bacteria will produce insulin.

I think you are right. Check your thinking here:
