Restriction endonucleases are most widely used in recombinant DNA technology. They are obtained from
1 Bacteriophages
2 Bacterial cells
3 Plasmids
4 All prokaryotic cells
Explanation:
Restriction endonuclease are most widely used in recombinant DNA technology. They are obtained from bacterial cells. Restriction endonucleases is act as molecular scissor in biotechnology. Stanley Cohen and Herbert Boyer first produced a recombinant DNA in 1972 by combining an antibiotic resistant gene with the native plasmid of bacterium Salmonella typhimurium.

There is a restriction endonuclease called EcoRl. What does "co" part in it stand for?
1 coli
2 colon
3 coelom
4 coenzyme
Explanation:
Exp: EcoRI is a restriction endonuclease enzyme isolated from species Escherichia coli. The Eco part of the enzyme's name originates from the species from which it was isolated, "E" denotes generic name \& "CO" denotes species name, "Coli" which is Escherichia coli, while the $\mathrm{R}$ represents the particular strain in this case RY13, and the I denotes that it was the first enzyme isolated from this strain.

Restriction enzyme was discovered by:
1 Waksman
2 Flemming
3 Berger
4 Smith and Nathans
Explanation:
Restriction enzyme (Restriction endonuclease) is an enzyme that cuts DNA of or near specific palindrome recognition nucleotide sequences known as restriction sites. Werner Arber, Hamilton Smith, and Daniel Nathans awarded Nobel Prize (1978). In physiology and medicine for developing the smaller names for the restriction enzymes. They performed experiments proving that there are certain enzymes produced by the bacteria which help in the cleavage of the genomes of the pathogens.

In gene cloning which of the following are used as vehicles for carrying foreign DNA fragment:
1 Host cell
2 Restriction enzymes
3 Adaptor
4 Vector
Explanation:
In molecular cloning, a vector is any particle (Ex- Plasmids, Cosmids, Lambda phages) used as a vehicle to artificially carry a foreign nucleic sequence, usually DNA into another cell where it can be replicated and or expressed a vector containing foreign DNA is termed recombinant DNA.
