If someone have consumed a drug that block the activity of primase. state the effect of drug on the synthesis of new dna strand.
Vanyuwa [196]

Answer:

The consumption of a drug that inhibits or block the enzyme primase will have problems for the replication of DNA, since it is not possible to synthesize a new strand without this enzyme.

Explanation:

During DNA replication, the enzyme primase is responsible for synthesizing the primers, RNA fragments necessary for the DNA polymerase III to synthesize the new DNA strand.

If for any reason the action of the primase is blocked, the primer could not be synthesized and the effect of DNA polymerase III would be null, so the new DNA strand could not be synthesized.

In DNA replication, the primase contributes to the formation of small fragments of DNA, by the action of polymerase III, which are called Okazaki fragments. These fragments will require the action of another enzyme, ligase, in order to form a continuous DNA strand.

When individuals of the same species are reproductively isolated, genetic differences may accumulate in sufficient number so tha
bogdanovich [222]

Answer:

b. founder effect

Explanation:

When there is a situation when sufficient number of members of one species are reproductively isolated, and if there is an evolutionary pressure for them to start developing new advantageous traits, then a new species will gradually emerge. In this kind of scenario the genetic diversity will be minimized, as the number of individuals is much smaller, and that will result in only changes that will go in only one direction and they will also occur quicker than if there was a greater genetic diversity. This is called the founder effect, and it is easy to see why this term has been chosen, as the limited number of members of a species that have been reproductively isolated are giving the foundation for the development of a new, separate species.
