Question

The restriction enzymes that cut the bacteriophage DNA cannot cut the bacterial chromosomal DNA.
Explain this statement.
The bacteria can cut the viral DNA at its specific restriction site, but they cannot cut their own DNA since bacterial chromosomal DNA has altogether a different DNA sequence than the viral DNA.
The bacteria can cut the viral DNA at its specific restriction site but protect their own chromosomal DNA by modifying its bases and blocking the restriction enzyme.
The bacteria can cut the viral DNA at its specific restriction site but protect their own chromosomal DNA by

Answer 1

modifying the restriction enzyme.

Answer 2

@Somy

Answer 3

I think the first bacteria .

Answer 4

i don't really know this one @Abhisar

Answer 5

Why not A ?

Answer 6

Well why should it be a ?

Answer 7

A restriction enzyme is an enzyme that cuts DNA at or near specific recognition nucleotide sequences known as restriction sites. This means that restriction enzyme is highly specific and cuts only the DNA for whose restriction sites it recognises.

Answer 8

Bacterial DNA has a different sequence and thus different restriction sites

Answer 9

got it ?

Answer 10

So a ?

Answer 11

Yep
