Mode of Gene Transfer
,• Genetic recombination - transfer of DNA from one
organism (donor) to another recipient. The
transferred donor DNA may then be integrated into
the recipient's nucleoid by various mechanisms.
Natural mechanisms of genetic recombination in
bacteria include:
a. transformation
b. transduction
c. conjugation
, Transformation
• When a cell takes up and expresses a new
piece of genetic material—DNA— in order
to change the organism’s traits
• A gene is a piece of DNA which provides
the instructions for making (coding for) a
particular protein
• A plasmid is a small circular piece of DNA
(about 2,000 to 10,000 base pairs) that
contains important genetic information
for the growth of bacteria.
