Question

99.9 percent of base sequence among humans is the same. Assuming human genome as 3x10^​​9 base pairs, in how many base sequences would there be differences?

Answer 1

Dear student,
99.9 percent of base sequence are same in human only 0.1 percent is different. Total genome size is 3 x 10⁹, therefore 0.1 percent of 3 x 10⁹ is 3 x 10⁶. So, total 3 x 10⁶ base pair difference is found in human genome of genome size 3 x 10⁹.
