Match List I with List II
| LIST I | LIST II |
|---|---|
| (Codes) | (Codes for) |
| A. UUU | I. Phenylalanine |
| B. AUG | II. Initiator codon |
| C. UAA | III. Terminator codon |
| D. GUU | IV. Valine |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → A-I, B-II, C-III, D-IV
(A) UUU — this matches (I) Phenylalanine. In the genetic code UUU (and UUC) codes for phenylalanine; it was among the first codons worked out.
(B) AUG — this matches (II) Initiator codon. AUG has a dual function: it codes for methionine and also starts translation.
(C) UAA — this matches (III) Terminator codon. UAA, UAG and UGA code for no amino acid and stop translation.
(D) GUU — this matches (IV) Valine. All four codons starting with GU (GUU, GUC, GUA, GUG) code for valine.
