It is possible to calculate the number of clones that must be present in a gene library to give a probability of obtaining a particular DNA sequence. This formula is:

 

where N is the number of recombinants, P is the probability and f is the fraction of the genome in one insert. Thus for the E. coli DNA chromosome of 5 × 10 ⁶ bp andan insert size of 20 kb ( f = 0.004), the number of clones needed ( N ) would be 1 × 10 ³ ,with a probability of P will be
