What are phages?
Viruses that infect bacteria
What are the two main types of phage infection cycles?
Lytic and lysogenic
How is plasmid DNA isolation different from isolation of total bacterial DNA?

In what conformation do plasmids exist?
Circular
What enzymes are used in DNA manipulation?
Polymerases, ligases, and nucleases
What is gene cloning?
The process of inserting a DNA fragment into a vector and propagating the recombinant DNA in a host organism to produce clones
Study Notes
- Gene cloning involves inserting a DNA fragment into a vector and propagating the recombinant DNA in a host organism to produce clones.
- PCR can also be used to isolate genes, but has limitations.
- Cloning vectors, such as plasmids and bacteriophage chromosomes, are used to construct recombinant DNA molecules.
- Plasmids are circular DNA molecules found in bacteria and other organisms, and can carry genes for useful characteristics.
- Different types of plasmids include resistance, fertility, virulence, col, and degradative plasmids.
- Phages are viruses that infect bacteria and have a simple structure consisting of DNA surrounded by a capsid.
- Phages have two main types of infection cycles: lytic and lysogenic.
- Isolation of plasmid DNA involves the same general procedure as isolation of total bacterial DNA.
- Plasmids exist as supercoiled molecules and can be separated based on conformation.
- Enzymes such as nucleases, ligases, polymerases, and DNA modifying enzymes are used in DNA manipulation.
