Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Restriction endonuclease with same sequence specificity and cut site
A
Isoshizomer
B
Neoschizomer
C
Isocaudomer
Explanation: 

Detailed explanation-1: -Isoschizomers and neoschizomers: An isoschizomer is a restriction enzyme that recognizes the same sequence as another.

Detailed explanation-2: -Isoschizomers are two restriction enzymes that share the same recognition sequence although they do not necessarily cut at precisely the same place.

Detailed explanation-3: -In these instances, the first enzyme found to recognize a particular sequence is known as the prototype, while others that cleave the same sequence are called isoschizomers. Some isoschizomers cleave at different positions from the prototype and these are called neoschizomers (5).
