Match the LIST-I with LIST-II
| LIST-I | LIST-II |
|---|---|
| Features | Processes |
| A. DNA → DNA | I. Translation |
| B. DNA → RNA | II. Reverse transcription |
| C. RNA → DNA | III. Transcription |
| D. RNA → Protein | IV. Replication |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → A-IV, B-III, C-II, D-I
(A) DNA → DNA — this matches (IV) Replication. A DNA molecule makes a copy of itself. Each new molecule keeps one old strand and one new strand, so replication is semi-conservative.
(B) DNA → RNA — this matches (III) Transcription. One strand of DNA is copied into RNA, by the enzyme RNA polymerase.
(C) RNA → DNA — this matches (II) Reverse transcription. The usual flow is from DNA to RNA, so this is the reverse. It is carried out by the enzyme reverse transcriptase of retroviruses.
(D) RNA → Protein — this matches (I) Translation. The sequence of codons in mRNA is read at the ribosome, and the amino acids are joined in that order.
