When a cell undergoing cellular division identifies that a chromosome misalignment had taken place the cell cycle stops until the error it's corrected.

Option two of the question states that the cell cycle will proceed uncontrollably, this is not the case for the error at hand. Although this can be a problem for cells and leads to the appearance of cancer, it is not caused by chromosome misalignment. As is the case with options 3 and 4.

The stop or delay in the cell cycle is what normally takes place in these situations. This stoppage is done by the spindle checkpoint, which prevents duplicate chromosomes from separating.

During this time, the error it's corrected. If a cell is not able to correct the error at this time, many situations can follow. However, the most likely is that the cell will undergo a programmed cellular death.

What type of virus uses RNA , and not DNA, as its genetic material?A. Retroviruses. B. Parvoviruses. C. Adenoviruses. D. Bacteri

anyanavicka [17]

Answer:

Explanation:

When these viruses insert their genome into the host cell, they usually have a reverse transcriptase enzyme that converts the RNA to DNA before it is integrated into the host genome. This is before the host cell machinery is hijacked to replicate the viruses components.

What is a codon and where is it found

fgiga [73]

A codon is a sequence of three nucleotides in DNA or RNA that codes for either a particular amino acid or tells the cellular machinery to start or stop using the code. It isn't located anywhere specific.
