What percentage of mutations

Assignment Help Biology
Reference no: EM131125831

The bacteriophage T4 genome contains about 50 percent A:T base pairs and 50 percent G:C base pairs.

The base analog 2-aminopurine induces A:T -> G:C and G:C -> A:T base-pair substitutions by undergoing tautomeric shifts.

Hydroxylamine is a mutagenic chemical that reacts specifically with cytosine and induces only G:C -> A:T substitutions.

If a large number of independent mutations were produced in bacteriophage T4 by treatment with 2-aminopurine, what percentage of these mutations should you expect to be induced to mutate back to the wild-type genotype by treatment with hydroxylamine?
