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

Solution & Step-by-step Explanation

The distance between two consecutive base pairs is 0.34 nm (0.34 \times 1 0^{- 9} m).Total length = (Number of bp) \times (distance between bp) 1.1 = n \times 0.34 \times 1 0^{- 9} n = \frac{1.1}{0.34 \times 1 0 ^{- 9}} \approx 3.23 \times 1 0^{9} bp This is approximately 3.3 \times 1 0^{9} bp . (Half of the diploid human genome content).

Try it yourself before checking the explanation above.

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

3.3 \times 1 0^{9} bp

6.6 \times 1 0^{9} bp

3.3 \times 1 0^{6} bp

6.6 \times 1 0^{6} bp
