Answer:
Restriction enzymes are DNA-cutting enzymes. Each enzyme recognizes one or a few target sequences and cuts DNA at or near those sequences.
Many restriction enzymes make staggered cuts, producing ends with single-stranded DNA overhangs. However, some produce blunt ends.
DNA ligase is a DNA-joining enzyme. If two pieces of DNA have matching ends, ligase can link them to form a single, unbroken molecule of DNA.
In DNA cloning, restriction enzymes and DNA ligase are used to insert genes and other pieces of DNA into plasmids.

Answer:
See the answer below
Explanation:
A DNase is also known as deoxyribonuclease and it is an enzyme that catalyzes the degradation of deoxyribonucleic acid by cleaving the phosphodiester linkage in their structures. Thus,<em> if the RNA is treated with a DNase before the plants are exposed to it, it will not make any difference. The plants will develop the same types of lesions as if they have been exposed to the mosaic virus.</em>
Unlike DNase, RNase is a ribonuclease, an enzyme that is capable of carrying out catalytic degradation of ribonucleic acids. <em>This means that if the RNA is treated with RNase before the plants are made to be exposed to it, they will not develop the lesions because the RNA would have been degraded by the enzyme.</em>
A protease is an enzyme that degrades the structure of proteins. <em>Treating a RNA with protease will thus have no effect on the structure of the RNA. Exposing the plants to the protease-treated RNA will make no difference. The plants will still come down with the lesions as if they have been exposed to the virus. </em>
