Host-pathogen interactions are an ongoing arms race; pathogens evolve to express unique structures that avoid host detection, and the host germline-encoded recognition system co-evolves to match these new challenges. However, because pathogens generally have much shorter life cycles than their vertebrate hosts, and some utilize error-prone DNA polymerases to replicate their genomes, pathogens can evolve rapidly to evade host encoded recognition systems. Which error prone DNA polymerase is used by human?

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

The body weight of offspring of bird species is range between 12 gm to 18 gm. In a laboratory experiment, species was subjected to selection pressure having influence on the offspring body weight. After many generations of experimental selection pressure, the body weight range between 16 gm to 24 gm. Which of the following natural selection operate on this species?
