Answer:

The main purpose of lab is to perform different experiments and importance of topic is that it supports essay's thesis statement.

Explanation:

In scientific research, lab plays a vital role because they have all the materials and equipment for experimentation. lab has a control environment where infestation of harmful organisms is minimum. On the other hand, topic is an argument which is made by the writer with the reasoning.

If you were to repeat the Meselson Stahl experiments, but rather than use N15 and N14, you use P32 and P31, how would the result
bonufazy [111]

Answer:

The correct answer will be option-C

Explanation:

The CsCl gradient centrifugation in Meselson Stahl experiments is done to separate the bands of the DNA containing isotopes on the basis of difference in the density.

In the experiment, bacterial cultures were grown in the medium of 15N and 14N but if we repeat the experiment with P32 and P31 instead of 15N and 14N and centrifugation is performed then the banding pattern will be the same as of the previous experiment as the method of the replication is same that is semi-conservative.

Thus, Option-C is the correct answer.

coat color in mice involves the interaction of multiple genes if a mouse has two recessive alleles for coat colorit is always al
AleksAgata [21]

Answer:

Epistasis

Explanation:

In epistasis, the interaction between genes is inimical, such that one gene masks or interferes with the expression of another. “Epistasis” is a word coined of Greek roots that mean “standing upon.” The alleles that are being masked or silenced are said to be hypostatic to the epistatic alleles that are doing the masking. The cause of the biochemical basis of epistasis is a genetic pathway in which the expression of one gene is dependent on the function of a gene that precedes or follows it in the pathway.

The example of epistasis given is the pigmentation of mice. we were told that "if a mouse has two recessive alleles for coat color,  it is always albino no matter what the genotype of other genes involved in coat color"

Let say recessive allele (rr), it is always albino irrespective of other type of other genes, this is true in the stance that epistasis can be reciprocal such that either gene, when present in the dominant (or recessive) form, expresses the same genotype.
