Question

If the distance between two consecutive base pairs is 0.34 nm and the total number of base pairs of a DNA double helix in a typical mammalian cell is 6.6 10^9 bp, then the length of the DNA is approximately:

Accepted Answer

Correct answer: B. (b) Given that, Distance between two consecutive base pairs =0.34 nm =0.34 10^-9 m Total number of base pairs =6.6 10^9 bp Length of DNA = Distance between two consecutive base pairs Total number of base pairs =(0.34 10^-9)m 6.6 10^9 bp=2.2 m

$If the distance between two consecutive base pairs is 0.34 nm and the total number of base pairs of a DNA double helix in a typical mammalian cell is 6.6 \times 10^{9} bp, then the length of the DNA is approximately:$
