Question

Genetic code is degenerate because

• A. Codons have same energy level
• B. Each codon has many meanings
• C. Many codons have same meaning
• D. Each codon has a different meaning

Answer 1

The correct option is C

Many codons have same meaning

The correct option is C.

Explanation of the correct option:

1. Genetic code is used to direct the sequence of amino acids during the synthesis of proteins.
2. The codon is a triplet and 61 codons code for amino acids.
3. There are 3 stop codons that do not code for any amino acids.
4. The code is mostly universal.
5. The code is said to degenerate because some amino acids are coded by more than one codon.

Final answer: Genetic code is degenerate because many codons have the same meaning.
