|---|---|
| (a) DNA-dependent DNA polymerase | (i) Semi-conservative replication |
| (b) Origin of replication | (ii) Enzyme catalyzing DNA synthesis |
| (c) Eukaryotic cell cycle | (iii) S-phase of cell cycle |
| (d) Polyploidy | (iv) Chromosomal anomaly |
A
a-ii, b-i, c-iii, d-iv
B
a-ii, b-iii, c-i, d-iv
C
a-i, b-ii, c-iv, d-iii
D
a-ii, b-i, c-iv, d-iii
Correct Answer
Option A
Detailed Explanation
DNA-dependent DNA polymerase is the enzyme responsible for synthesizing DNA during replication, which occurs in a semi-conservative manner. The origin of replication is crucial for starting this process, and in eukaryotes, DNA replication takes place during the S-phase of the cell cycle. A failure in this process can lead to polyploidy, a chromosomal anomaly.
