Question

The length of a DNA double helix increases by 0.34 nm (nanometres) for every pair of nucleotides. The total number of nucleotides in a human body cell is
$1.2 \times {10}^{10}$

Calculate the total length of a double helix in a human body cell (answer to be given in meters)

Pls give me a quick answer​

Answer 1

(0.34 x 10^-9)(1.2 x 10^10) =4.08m
