Given the distance between two consecutive base pairs is 0.34nm=0.34×10−9m.
A total number of bases =6.6×109bp.
Length of DNA = Total no. of bp×Distance between two consecutivebp
=6.6×109×0.34×10−9
=2.24m
If the distance between two consecutive base pairs is 0.34nm and the total number of base pairs of a DNA double helix in a typical mammalian cell is 6.6×109bp bp, then the length of the DNA is approximately
