DNA of bacterium is not cleaved by its own restriction enzymes because the recognition DNA requences are (A) Methylated (B) Deleted (C) Bound by inhibitory proteins (D) Absence of recognition sequence

How does a bacterial cell protect its own DNA from restriction enzymes?

Type-II restriction enzymes are preferred over type-I in cleaving DNA strand because they

The restriction endounclease of a cell does not cleave it's own DNA because of

Explain briefly (a) PCR (b) Restriction enzymes and DNA (c) Chitinase

The ratio of A + T/G + C is constant for a species. Restriction enzymes will cut only at a specific DNA sequence.

A restriction enzyme Eco RI from E. coli is expected to cleave DNA at following sequence:

Restriction enzymes that are used in the construction of recombinant DNA are endonucleases which cut the DNA at specific recognition sequence? What would be the disadvantage if they do not cut the DNA at specific recogniion sequence?
