1) Describe the three kind of the recombination among microorganisms.

DNA is transferred horizontally among same generation.

The phenotype of gene at end of recombination will be changed.

a) Transformation (DNA transferred as naked DNA).

b) Transduction (has no contact, use vector virus).

c) Conjugation (need contact: pili).

2) Select on kind and explain it in detail with the help of concrete examples.

1) Explain and compare the plasmid and transposon.

2) Explain the role or significance of the transposon in the mechanism of cancer.
