Observe the table and answer the given question:

Identify the statements which are true with respect to the table given above.

(A) There are 64 codons coding for twenty amino acids
(B) The codon for methionine is CUG
(C) Serine and Leucine have 6 codons each coding for them
(D) UAA is a stop codon

Choose the correct answer from the options given below:

(C) and (D) only

The correct answer is Option (3) → (C) and (D) only

A) There are 64 codons coding for twenty amino acids

• False: There are 64 codons in total, but not all of them code for amino acids. Three of these codons (UAA, UAG, and UGA) are stop codons that do not code for any amino acids.

(B) The codon for methionine is CUG

• False: The codon for methionine is AUG, not CUG. CUG codes for leucine.

(C) Serine and Leucine have 6 codons each coding for them

• True: Both serine and leucine indeed have 6 codons coding for them.
• Serine: UCU, UCC, UCA, UCG, AGU, AGC
• Leucine: UUA, UUG, CUU, CUC, CUA, CUG

(D) UAA is a stop codon

• True: UAA is indeed one of the stop codons, along with UAG and UGA.

The statements that are true are: (C) and (D) only
