PLASMID
Plasmid is a double DNA molecule in a ring shape that only exists
in bacteria. In genetic manipulation activity, plasmid functions as vector
(vehicle) used to transfer and duplicate foreign genes.

Plasmid, a bacteria cell part that has important roles in genetic manipulation activity
ENZYME
The two kinds of enzyme involved in genetic manipulation process are as follows.
- Restriction endonuclease enzyme functions to cut DNA chain, so that it is called biology scissors. This enzyme has abilities to recognize and cut specific nucleotide series in DNA. !
- Ligase enzyme functions to adhere DNA fragments. Look above Picture
Mechanism in the enzyme's work. Nucleotide series known as restriction enzyme, sticky end' motecule of ecombinant DNA

Propofol is a short-acting, intravenously administered hypnotic/amnestic agent. Its uses include the induction and maintenance of general anesthesia, sedation for mechanically ventilated adults, and procedural sedation. Propofol is also commonly used in veterinary medicine. It is approved for use in more than 50 countries, and generic versions are available.
