What to Focus On
- Recombinant DNA technology is another name for genetic engineering.
- It involves direct manipulation of DNA or genome.
- Gene cloning means isolation and propagation of a desired gene to obtain its product in large quantity.
- Biotechnology was first named in 1917.
- DNA was established as genetic material in 1944.
- Plasmids were discovered in 1952.
- Restriction enzymes cut DNA at specific sites.
- Ligase joins DNA fragments.
- Type I and Type II restriction enzymes are different.
Common Mistakes to Avoid
Restriction enzymes and ligase do the same job in recombinant DNA technology.
Stanley Cohen and Herbert Boyer had the same expertise before developing recombinant DNA technology.
Type I and Type II restriction enzymes are the same discovery and can be used as one category.
