Cohen and Boyer are known for which of the following discoveries?

If you transform a cell with an alien piece of DNA only, What is the possibility?

1.      This alien piece becomes a part of the host genome.

2.      It doesn't become a part of the host's genome but keeps on replicating

3.      The cloning of genes won't get affected in the absence of Origin of replication.

4.     Multiple identical copies of an alien piece of DNA can be formed irrespective of its integration into the host's genome.

The cutting of DNA at specific locations became possible with the discovery of 

(1) restriction enzymes

(2) probes

(3) selectable markets

(4) ligases

In 1960’s two enzymes were discovered in bacteria that were responsible for providing immunity against bacteriophages. One was Restriction Endonuclease and the other was

1. Methylase

2. Exonuclease

3. Aminotransferase

4. Terminal Transferase
