Same day, different lectures

The topic was on Genetic transfer and recombination. In all of the mechanism, transferred involved; --donor cell- that give a portion of its total DNA --recipient cell- that received a portion of DNA from donor cell --parts of donor DNA is incorporated into the recipient DNA --when some of the donor’s DNA has been integrated into the recipient’s DNA, the resultant cell is called a recombinant.

Genetic transfer in prokaryotes:

 

•Transformation –gene transfer from one bacterium to another as ‘naked’ DNA in solution

 •Transduction –donor DNA transfer is mediated by a virus   

       

                                                              

 •Conjugation –transfer involve cell to cell contact –conjugative plasmid is the donor cell
