If the M checkpoint is not cleared, what stage of mitosis will be blocked?

Biology
1 answer:
goblinko [34]3 years ago
7 0

Answer:

Anaphase

Explanation:

The M check-point of the cell cycle regulates the cell cycle by checking if all the chromosomes are attached properly to the spindle fibers. This checkpoint also ensures that chromosomes are aligned properly at the cell's equator.

If these conditions are met, the M checkpoint allows the cells in the metaphase to progress towards the anaphase. However, any deviation from above-mentioned conditions prevents the cells in the metaphase to enter the anaphase.

How are alleles for the same gene related? A. They have different genetic sequences but are found in the same location on a chro
Dmitrij [34]

Answer:

A. They have different genetic sequences but are found in the same location on a chromosome.

Explanation:

In genetics, alleles are the variant form of a gene. According to Mendel, there are usually two alleles for most genes except for few cases where there are multiple alleles. Each allele of a pair is contributed by each parent during sexual reproduction. For example, in a gene Tt, the alleles are T for tallness and t for shortness.

Alleles of the same gene are related in such a way that they have different genetic sequences but are found in the same location on a chromosome. The different genetic sequences makes them alternative form of each other.
