recombinant DNA
a DNA molecule that includes any nonparental nucleotide sequences
genetic engineering
deliberate changing of DNA
gene trasfer
movement of genetic information between organisms
transormation
living cells incorporating naked DNA
log (secrets a protein called competence factor)
transduction
uses a virus to transfer genes
bacteriaphage
virus which infects bacteria
lytic cycle
viral nucleic acid becomes part of cellular DNA, takes over cell & has cell produce new viruses, then rupture
lysogenic cycle
viral nucleic acid becomes part of cellular DNA & then becomes dormant. may or may not enter lytic cycle in the future
conjugation
uses direct contact with pili to tranfer plasmids
Resistance plasmids
carry genes that provide resistance to specific toxins or antibiotics
transpoosons plasmids
transposable element that contains the genes for moving and one or more genes as well
bacteriocin plasmids
proteins that inhibit growth. directs the productions of them
