Your colleague has isolated a mutant bacterial strain and foundthe dna 5x10^8 bp in length. she has asked you to do restrictionmapping. you start by determining the base composition of thebacterium, and find that the bacteria consists of 24% Thymine and26% Guanine. you plan on using the enzyme NOTI which recognizes thesequence 5'-GCGGCCGC-3'
a) How many fragments would you expect assuming that it occursrandomly throughout the genome
b)your colleague also provided several variants of her strain ofbacteria. You test all of them and found differences in theirrespective banding pattern, in a simple statement, what couldaccount for this?
