NEET Botany DNA Replication MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Which of the following combinations correctly describe the process of DNA replication?
A
It occurs at the S-phase of the cell cycle and involves DNA-dependent DNA polymerase.
B
It requires RNA-dependent RNA polymerase to synthesize new DNA strands.
C
The process is semiconservative and involves the use of vectors for replication.
D
It is a highly coordinated process that leads to polyploidy when mismanaged.
Correct Answer
Option A
Detailed Explanation
DNA replication occurs during the S-phase of the cell cycle and primarily involves DNA-dependent DNA polymerase, which uses a DNA template for synthesizing new strands. The process being semiconservative is also highlighted in the context of experiments that demonstrated DNA replication.
