3.24 b Mitosis

Key Points:
1. Covering the basics, mitosis is the process in which a cell divides into two cells, which have identical properties such as sets of chromosomes.
2. This requires that the first cell has to copy its chromosomes. This process is known as DNA replication. In the process, each chromosome undergoes a copy process to produce a replica of it with the same genes and alleles and they are held together by a structure called the central mere.
3. While the chromosomes are held together, they are referred to as a pair of chromatids.
4. The process of DNA replication takes place inside the nucleus, while its still intact. Its not visible. This is known as the inter phase.
