Explanation:
The answer is 8 (anaphase 1), 8 (anaphase 2), 4 (metaphase 2).
Meiosis is a cell division which results in a reduction of the number of chromosomes in half and it consists of meiosis I and meiosis II.
Before meiosis I begins, the cell is diploid (2n) and there are 8 chromosomes. In anaphase I<span>, the sister chromatids separate from each other to the opposite sides of the cells, and after that, there are 8 chromosomes and 16 chromatids. After telophase I, there are, however, <u>4 chromosomes that enter meiosis II</u>.

Meiosis II is similar to mitosis. So, in metaphase II there is the same number of chromosomes - 4 chromosomes. But, the chromosome number must double so in anaphase II there will be in total 8 chromosomes - 4 chromosomes at the one side of the cell and the 4 on the other side. After telophase II, there are 4 chromosomes.
Answer:
Cell division is the process in which one cell, called the parent cell, divides to form two new cells, referred to as daughter cells. How this happens depends on whether the cell is prokaryotic or eukaryotic. Cell division is simpler in prokaryotes than eukaryotes because prokaryotic cells themselves are simpler.

Explanation:
The DNA could be dried -through the process of lyophilization- or stored, as a precipitate of ethanol, in liquid nitrogen (temperatures below -80 degrees Celsius). The aim is to reduce water in the stored samples as much as possible because the water can be involved in natural hydrolytic reactions (depurination, depyrimidination, deamination, and hydrolytic cleavage) that could degrade the nucleic acids of the DNA.
If the DNA is stored while being used regularly it is not advisable to store it as a precipitate of ethanol. It should be stored in aqueous form but in a slightly alkaline pH of about 8.5 to prevent acid-catalysed degradation processes.
