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.
