Answer the following question.
State the importance of a Genetic code in protein biosynthesis.

Solution
The genetic code is a set of three different nucleotides taken at a time that code for a specific amino acid.
- A codon is a triplet. 3 4 = 64 (61 codons code for amino acids while 3 are stop codons)
- One codon codes for a single specific amino acid. Codons are unambiguous.
- Codons are degenerate since some amino acids are coded by more than one codon.
- The genetic code is universal. 1 codon codes for the same amino acid in all species.
- Codons are read continuously. They lack punctuation.
- AUG has dual functions - Codes for Methionine and acts as a start codon
