This is because there might not be one restriction site bordering the gene to be cloned and the identical restriction site in the plasmid. Since these two restriction enzymes make compatible sticky ends, the insert has a chance of combining with the plasmid. To ensure efficient digestion, the two recognition sites should be more than 10 base pairs apart. If one of the enzymes is a poor cutter or if the sites are separated 10 base pairs or less, the digestions <span>should be performed sequentially</span>
"A gene pool consists of all genes, including all the different alleles that are present in a population. Number of times an allele occurs in a gene pool compared with the number of times other alleles occur. In genetic terms, evolution is any change in the relative frequency of alleles in a population."
The answer is gene mutation.
Albinism is a congenital disorder characterized by a complete or partial absent of pigment in skin, eyes or hair. It is a recessive disorder, which means that parents must not have the disorder. But if both of them carry a recessive allele, and offspring inherit the recessive alleles from mother and father, the offspring will have albinism. Anyway, it is pretty rare, since it is the recessive trait, and most of the offspring will have normal coloring.
The main benefit of nonrenewable energy is that they're abundant and affordable.<span />
<em><u>Answer:</u></em>
They generate chemical energy in the form of ATP.
<u><em>Explanation:</em></u>
Mitochondria are the powerhouses of the cell because they "burn" or break the chemical bonds of glucose to release energy to do work in a cell. This releases energy (ATP) for the cell. The more active a cell (such as a muscle cell), the more mitochondria it will have.
