Question:
During replication of DNA, each separated parent DNA strand acts as ___________.
During replication of DNA, each separated parent DNA strand acts as ___________.
Show Hint
In semi-conservative replication each old strand guides the making of a new one by base pairing.
Updated On: Nov 12, 2026
- sense strand
- antisense strand
- template strand
- parallel strand
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
During replication helicase separates the two strands of DNA at the replication fork.
Step 2: What each strand does
DNA polymerase adds nucleotides complementary to each old strand (A with T, G with C).
Thus every parent strand guides the sequence of its new partner.
Step 3: Name
A strand that guides the making of a new strand is a template strand.
Final Answer:
Each separated parent strand acts as a template strand. \[ \boxed{\text{(C) }\text{template strand}} \]
