In the double helical structure of DNA molecule, the strands are:
In the double helical structure of DNA molecule, the strands are:
Show Hint
DNA strands are complementary (A with T, C with G) and anti-parallel, meaning one strand runs in the opposite direction of the other.
Updated On: Jan 13, 2026
- identical and complementary
- identical and non-complementary
- anti-parallel and complementary
- anti-parallel and non-complementary
Show Solution
The Correct Option is C
Solution and Explanation
DNA's double helix features two complementary strands: adenine binds with thymine, and cytosine binds with guanine. These strands are antiparallel, running in opposite 5’ to 3’ and 3’ to 5’ orientations.
