Meiosis is also called ___ cell division.Cell divisionCell division is the process through which cells give origin to other cells. Cell division is perhaps the most defining characteristic of life: a cell under division will not only give origin to two new cells, but it will also preserve...
What is the parent cell in meiosis? Cell Undergoing Meiosis In order for cells to undergo meiosis the DNA must first be replicated. This allows the DNA to exchange genes in a process called crossing over. When this is combined with the independent assortment of the chromosomes in metaphase I...
Cell division is the process that cells use to duplicate themselves. There are two main types of cell division: mitosis andmeiosis. Mitosis is the process that cells use to duplicate themselves for growth and repair. Meiosis is the process that cells use to create gametes, such as sperm and ...
Course 4.2Kviews Four Stages of Mitosis Mitosis contains four stages that each have a specific role to perform. Prophase Prophaseis when the parent cell prepares for division. Because the cell needs to divide into two identical cells, each of the parent cell's duplicated organelles need to be...
Meiosis is similar to mitosis in many ways, but there are a couple of important differences. First of all, even though meiosis starts with a diploid cell (a primary oocyte or primary spermatocyte), its end products are 4 haploid daughter cells, each with 23 chromosomes. Instead of being ...

The G1, S and G2phases are collectively termed interphase. The rest of the cell cycle is concerned with cell division – mitosis in somatic cells, meiosis in the specialized cells of gonads. The stages of mitosis and meiosis are collectively called the M phase, potentially introducing confusion...
Mammalian cells have evolved specialized mechanisms to sense and repair double-strand breaks (DSBs) to maintain genomic stability. However, in certain cases, the activity of these pathways can lead to aberrant DNA repair, genomic instability and tumorigenesis. One such case is DNA repair at the na...
References 99 and 100 use quantitative mass spectrometry to examine the kinetics of histone methylation mark restoration after replication in HeLa cells, which shows that these marks are not fully restored until after mitosis. PubMed PubMed Central Google Scholar Petruk, S. et al. TrxG and ...
Mitosis involves a single cell division that results in two identical daughter cells, while meiosis consists of two successive divisions, producing four genetically distinct gametes.
