Lecture 5: Bacteria, Viruses, Parasites
-
GENOMES
Viruses
RNA coat - HIV, Coronavirus, influenza
-
-
-
Microbrial DNA transfer
-
Horizontal transfer
Conjugation
-
-
Steps
Initial steps
- Pilus tip of F+ cell binds to receptor on surface of F- cell
- Retraction of pilus brings F+ and F- cells close together
- Formation of the conjugative bridge, an opening between the cytoplasm of the two cells
DNA transfer steps
- . One strand of DNA is nicked at the oriT site
(only one of the two DNA strands is cleaved)
- One DNA strand is pushed through the
conjugation bridge
-
- F- recipient uses incoming DNA as a template
for DNA synthesis
- DNA transfer/synthesis completed and cells
separate

Microprojectiles enter the cells, transgenes
may incorporate into chromosomal DNA
