Question

Assuming the frequency of a base pair change is 10-9 per base pair per generation, how many base pair changes will have occurred in a new daughter cell as compared to the mother cell (i.e. one generation) if the genome size is 6 x 109 bp

Answer 1

The options:

a) 6

b) 6000

c) 6 x 10^19

d) 0.6

The CORRECT ANSWER IS a)

a) 6

Step-by-step explanation:

Base pair changes

= genome size × frequency of a base pair change

Given,

genome size = 6 x 10^9 bp

frequency of a base pair change = 10^-9

=6 x 10^9 x 10^-9

= 6 × 10^9+(-9)

= 6 × 10^9-9

= 6 × 10^0

= 6 × 1

= 6 base pair changes
