These new combinations result from the exchange of DNA between paired chromosomes ... Finally, unlike mitosis, meiosis involves two rounds of nuclear division, not just one.

the proper amount of DNA is maintained. This solution is called meiosis. Mitosis describes the process by which the nucleus of a cell divides to create two new nuclei, each containing an identical ...

So, it's very easy to see,” she said. To zoom in on changes in chromosome organization during meiosis, the researchers used nuclear membrane and DNA damage protein stains to track nuclear behavior.

During meiosis, a diploid parent cell, which has two copies of each chromosome, undergoes one round of DNA replication followed by two separate cycles of nuclear division to produce four haploid ...
