Question

Match the following column.

$\begin{array}{cccc}& \text{Column-I}& & \text{Column-II}\\ & \text{(Triplet codons)}& & \text{(Amino acids)}\\ \text{A}& \text{UUU}& \text{(1)}& \text{Alanine}\\ \text{B}& \text{CCC}& \text{(2)}& \text{Glycine}\\ \text{C}& \text{AAA}& \text{(3)}& \text{Lysine}\\ \text{D}& \text{GGG}& \text{(4)}& \text{Proline}\\ & & \text{(5)}& \text{Phenylalanine}\end{array}$

• A. (A)–4, (B)–5, (C)–2, (D)–3
• B. (A)–5, (B)–4, (C)–3, (D)–2
• C. (A)–1, (B)–2, (C)–4, (D)–5
• D. (A)-2, (B)-3, (C)-4, (D)–5

Answer 1

The correct option is B (A)–5, (B)–4, (C)–3, (D)–2

The genetic code is made up of three bases that arises from the sequence of mRNA and give rise to amino acids. According to the universal genetic code:

• UUU codes for phenylalanine.
• CCC codes for proline.
• AAA codes for lysine.
• GGG codes for glycine.
