Question

Which statement is correct?
(A) Degeneracy of code is related to third member of codon.
(B) Single codon codes for more than one amino acid.
(C) In codons, first two bases are more specific.
(D) In codons, third base is wobble.
(E) Code is universal.

• A. A, B, C, D, E
• B. A, B, D
• C. A, C, D
• D. A, C, D, E

Answer 1

The correct option is D A, C, D, E

All the statements are correct except for (B) because, the genetic code expresses in a way that 64 Codons constitute it, as it occurs in triplets. According to the genetic code, three bases must be employed to encode the 20 standard amino acids used by living cells to build proteins. With four different nucleotides, a code of 2 nucleotides would allow for only a maximum of 42 = 16 amino acids. A code of 3 nucleotides could code for a maximum of 43 = 64 amino acids
