If there are 2.9xx10^(9) complete turns ...

If there are `2.9xx10^(9)` complete turns in a DNA molecule. Estimate the length of the molecule (1 angstrom `=10^(-8)` cm).

Text Solution

Verified by Experts

1 turn of DNA `=3.4` nm.
Number of turns are `=2.9xx10^(9)`
The length of the DNA molecule `=2.9xx10^(9)xx3.4` nm.
