What type of mutation occurs when a nucleotide is added to the DNA?

Yanka [14]

Answer:

A frameshift mutation.

Explanation:

A frameshift mutation is when one adds an extra nucleotide to a series of nucleotides. This will mess up the order of the nucleotide, thus when it forms the codons, and eventually, the amino acids; all of the codons are wrong, thus all of the amino acids are wrong.

In this situation, an extra nucleotide is added to a sequence of DNA, this results in all of the other nucleotides getting pushed over by (1). Thus, all of the nucleotides form the wrong codons and the wrong amino acids. Therefore, a frameshift mutation has occured.

A cell undergoing cell division identifies a chromosomal misalignment. How does this normally affect the progress of the cell cy

telo118 [61]

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.
