Although restriction enzymes are quite efficient at digestion of foreign DNA, they are prevented from acting on the DNA of host

cells by: The inability of host cell DNA to be bound to the active site of the enzyme. The presence of competitive inhibitors which prevent the enzymes from binding to the host DNA. The methylation of bases in recognition sequences in host cell DNA. The inaccessibility of host cell DNA for the enzymes.

Answer:

Restriction enzymes are quite efficient at digestion of foreign DNA, they are prevented from acting on the DNA of host cells by the methylation of bases in recognition sequences in host cell DNA - Option C.

Explanation:

A bacterial cell that produces a restriction enzyme does not have its own DNA, although , due to restriction modification system, it contains diverse restriction sites for the recognition enzyme.

The modification system includes the modification enzyme - DNA methylase, which recognizes the modification site and modifies the site by the addition of a methyl group to one or two bases.

Some of the drugs used to treat hiv patients are competitive inhibitors of the hiv reverse transcriptase enzyme. unfortunately,
REY [17]
Such changes would occur mostly likely near or in the active binding site of the enzyme.
Because the drugs used are competitive inhibitors of the <span>HIV reverse transcriptase enzyme, it means that they connect directly to the active binding site of this enzyme not allowing it to preform its function. If the mutations impede this drugs to work, it is probably because they alter the active binding site of the enzyme, not allowing the drug to bind and have its competitive behaviour permitting the enzyme to work normally. </span><span /><span>
