In bacteria, the restriction enzyme plays an important role in defence against viral infection by chopping foreign DNA into pieses, but it does not cut its own DNA because of

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

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

What is the role of restriction enzymes in bacteria ? How do they protect their own DNA being cut by the restriction enzymes?

How does bacterial DNA is protected against restriction enzymes?

When a typical restriction enzyme cuts a DNA moleule, the cuts are uneven so that the DNA fragments have single-stranded ends . These ends are useful in recombinant DNA work because :

When a typical restriction enzyme cuts a DNA molecule, the cuts are uneven, so that the DNA fragments have single-stranded ends. These ends are useful in recombinant DNA work because

A: DNA ligase plays an important role in recombinant DNA technology. R: The linking of antibiotic resistance gene with plasmid vector became possible by enzyme DNA ligase
