Question

Why is genetic code triplet, not doublet?

Answer 1

Genetic code:

1. The genetic code is a set of codons that undergoes translation to produce proteins.
2. The genetic code exists as triplets and not as a singlet or doublet because it doesn't provide enough information to synthesize proteins.
3. There are only four nucleotides - A, C, G, and U.
4. If the genetic code exists in a doublet format, only 16 different amino acids (4x4) can be formed.
5. A triplet code gives rise to 64 different combinations (4x4x4) and forms 20 amino acids.
6. Each triplet code is unique and forms different amino acids.
