What to Focus On
- Genome means total genetic material of a cell
- Prokaryotic genome includes nucleoid DNA and plasmids
- Eukaryotic genome includes nuclear, mitochondrial, and plastid DNA
- RFLP is a restriction site based physical mapping technique
- Fragments are visualised on agarose gel
- Circular and linear DNA give different fragment numbers after cutting
- First generation sequencing used PFGE, cloning vectors, and chain termination
- Each capillary reads about 800 to 1000 bases
- A 96-capillary machine can give up to 96000 bases per run
Common Mistakes to Avoid
Genetic mapping and physical mapping are the same thing.
Decreased recombination frequency means the loci are farther apart.
RFLP is based on repeat sequence length, like SSLP.
Memory Tips
Genome definition and its parts in prokaryotes and eukaryotes
Genetic mapping uses recombination frequency
Centimorgan as the unit of genetic distance
Genetic maps are sparsely populated
