हिन्दीIf the distance between two consecutive base pairs is \( 0.34 \text{ nm} \) and the total number of base pairs of a DNA double helix in a typical mammalian cell is \( 6.6 \times 10^9 \text{ bp} \), then the length of the DNA is approximately:
Correct answer · Option 2
2.2 meters
Explanation
Length = \( 6.6 \times 10^9 \text{ bp} \times 0.34 \times 10^{-9} \text{ m/bp} = 2.244 \text{ meters} \approx 2.2 \text{ meters} \).
