DNA polymerase
|
enzyme involved in replication, adds nucleotides in 5' to 3' orientation
|
|
|
primase
|
synthesizes RNA primer
|
|
|
DNA ligase
|
creates phosphodiester bonds that connect lagging strand segments
|
|
|

|
Transduction (horiz DNA transfer)
|
viral vector
|
|
|
Transduction A
|
viral particle injects its nucleic acids into bacterium, viral DNA is replicated along w/ bacterial genome, bacterial cells lyses and viral particles are relesased
|
|
|
Transduction B
|
viral particle injects it nucleic acids, viral DNA is incorporated into bacterial genome
FINISH |
