Question

Hey again! Another Genetics problem:

The DNA of a mutant virus has a length of 15 µm instead of 17 µm. How many base pairs
are missing from the mutant?

How I think:
1) Firstly count how many base pairs are in non-mutant organism
2)Then got the answer how many base pairs are in mutant organism
3)Number of base pairs of non-mutant MINUS number of base pair of mutant organism=how many base pairs are missing.

Am I right?

How I would count? number of base pairs=length of genome/base pair lenght (0.34x10^-9nm). Is it correct?

Answer 1

@Nurali maybe you could have a look?:)

Answer 2

@amistre64 maybe you could help me?

Answer 3

what is the length of 1 base pair?

Answer 4

sorry - it is 0.34nm or 0.34x10^-9 m: } I already found out the answer, but thanks anyways. All I have to do is 17µm-15µm=2µm which is 2x10^-6 m

then 2x10^-6/0.34^10-9 ~ 5.88x10^3
