What will be the length of a DNA molecule containing 10 million bp?
Select an option to attempt
Correct Answer: Option C
Explanation
Length of a DNA molecule with 10 million base pairs:Key fact: In B-form DNA, the rise per base pair = 0.34 nm (the distance along the helical axis per bp).For context: The human genome has ~3.2 billion bp → ~1 metre of DNA per cell.Answer: 3.4 mm (Option 3).
