Question

calculate length of dna in human cell if total no. of bp are 6.6*10*9 and distance bw two consecutive bp is 0.34nm

Answer 1

Explanation:

ANSWER

The distance between two consecutive base pair is 0.34 nm (0.34X10

−9

m). The length of DNA for human diploid cell is 6.6X10

9

bp x 0.34X10

−9

m =2.2 metres. This length is far greater than the dimension of a typical nucleus which is approximately 10

−6

m. The long-sized DNA can be accommodated in the small area only through packaging or compaction.
