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.

The question is incorrect. The correct question is as follows:

The client is admitted to the telemetry unit diagnosed with acute exacerbation of congestive heart failure. Which S/S would the nurse expect to find when assessing this client? a. apical pulse rate of 110 and 4+ piting edema of feet b. thick white sputum and crackles that clear with cough c. the client sleeping with no pillow and eupnea d. radial pulse rate of 90 and capillary refill time

Answer:

Apical pulse rate of 110 and 4 pitting edema of feet.

Explanation:

Congestive heart failure may be defined as the medical condition in which the pumping ability of the heart becomes abnormal. This might occur due to the accumulation of fluids in the heart.

The most common sign and symptoms of congestive heart failure is the increase in the apical pulse rate of around 110. The individual might suffer from different heart sounds, require two pillows for sleep and deposition of body fluids.

Thus, the correct answer is option (a).

Among pea plants, we see more peas with smooth pods than with constricted pods. if a plant with constricted pods is mated with a
Novay_Z [31]
OK if we said the the allel for smooth is (S ) and it is dominant and the allel for constricted is (s) and it is recessive , so we started by mating two pure pea plant one smooth and one constricted the offspring would have a genotype of (Ss) and it'S phenotype is smooth, and if that offspring did self pollination it will produce 4 offsprings with genotype as follow: 1 (SS) : 2 (Ss ) : 1 (ss) so there would be 3 smooth and one constricted which will be the last one (ss )
