More than 900 restriction enzymes have been isolated from

Assertion : Besides HindII, today we know more than 900 restriction enzymes that have been isolated from over 230 strains of bacteria Reason :Each restriction enzyme recognises different recognition sequence

Restriction enzymes are :

Correct statement about restriction endonuclease. (I) It is the enzyme which cuts DNA at a particular point. (II) The first restriction endonuclease was Hindll. (III) Overall,900 restriction enzymes have been isolated from about 200 strains. (IV) Each restriction endonuclease recognizes a specific palindromic sequence.

Approximately how many restriction enzymes have been isolated from the different (over 230) strains of bacteria:

Select the correct option regarding restriction endonuclease P. 900 restriction enzyme have been isolated from over 200 strains. Q. The first restriction exonuclease was Hind II. R. Each restriction endonuclease recognises same palindromic sequence .

Recombinant DNA technology become possible only after the discovery of enzyme restriciton endonuclesase till now how many restriction enzymes have been isolated .
