If the length of a DNA molecule is 1.1 metres, what will be the approximate number of base pairs?

  1. A
    \( 3.3 \times 10^6 \text{ bp} \)
  2. B
    \( 6.6 \times 10^6 \text{ bp} \)
  3. C
    \( 3.3 \times 10^9 \text{ bp} \)
  4. D
    \( 6.6 \times 10^9 \text{ bp} \)
View Answer & Solution

Correct answer · Option C

\( 3.3 \times 10^9 \text{ bp} \)

Explanation

Number of base pairs = \( \frac{\text{Total length}}{\text{Distance between two consecutive base pairs}} = \frac{1.1 \text{ m}}{0.34 \times 10^{-9} \text{ m}} \approx 3.3 \times 10^9 \text{ bp} \).
