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 10^9 bp?a. 6b. 6000c. 6 x 10^18d. 0.6

Answer 1

Option A,
`6`

Step-by-step explanation:

Given -

Frequency of change of base pair

`= (10^(-9))/(bp)` per generation

To calculate the number of base pair changes , the following formula can be used -

Number of base pair changes
`=`frequency of base pair change per generation per base pair
`*` total number of base pairs
`*` total number of generations

Substituting the given values in able equation we get -

Number of base pair changes

`= (10^(-9)) * (6*10^9)* (1)\\= 6`

Hence, option A,
`6` is correct.
