The two cell division processes that use DNA replication are mitosis and meiosis. Mitosis is the process of cell division that makes new body cells. ... Learn more about this topic: DNA Replication | How, When & Why? from Chapter 4/ Lesson 2 78K Understand how DNA is replicated. Learn ...

During which phase of mitosis do the chromatids become chromosomes? How can somatic cell mutations affect offspring? In which phase of Meiosis 1 does tetrad occur? How often do mutations occur? What happens to a somatic cell when its DNA replicates? Does DNA rep...
In mitosis, by contrast, homologous chromosome pairs never or very rarely interact. Each mitotic chromosome duplicates, forming two sister chromatids, and then these two identical sister chromatids separate to opposite poles. While mitosis is specialized to produce entirely identical progeny, meiosis ...
Replication of DNA Before a cell can divide by mitosis or meiosis, it must first make a copy of its chromosomes. The DNA in the chromosomes is copied. DNA Replication What is replication? When does replication occur? Why do we need replication?
How selection pressures affect genome-wide DNA methylation levels in natural plant populations have been reported inArabidopsis thaliana. Apart from genetic factors, variations in DNA methylation can arise either by altered methylation marks during mitosis or meiosis by chance, or in response to environm...
Centromere alterations such as the appearance of neocentromeres and dicentric chromosomes generated by chromosome rearrangements are also found in disease and most of the time, once formed, are remarkably stable during both mitosis and meiosis. While more is known about how dicentric chromosomes form ...

(i.e., in G2/mitosis). Although the results of such an experiment cannotprovide evidence of the nature of the observed L1-linked DNA synthesis by reversetranscription (a potential synthesis of extragenomic L1 DNA copies cannot be ruledout), this approach could be a good starting point to ...
