Q4 of 4 Page 1

How many base pairs would a DNA segment of length 1.36 mm have?

The length of two base pairs = 0.34nm = 0.34 * 10-9 m


We know that the total length of a double stranded DNA is calculated in the following way: Total number of base pairs x Distance between two base pairs.


Here we have, total length of the DNA segment= 1.36 mm or


1.36 * 10-3 m


So, the number of base pairs that this DNA segment will have


= Total length of DNA segment / Distance between two base pairs


= (1.36 x 10-3 ) / 0.34 x 10-9 m


= 4 x 106 base pairs


Therefore, the number of base pairs that a DNA segment of


length 1.36mm would have is 4x106 base pairs.
