Replication
A part of procreation and growth is the ability to pass on and duplicate genetic material. The process of mitosis and meiosis all happen in the nucleus. Animal and bacterial cells do this process differently. Bacterial cells divide be binary fission, and pass on plasmids which is circular chromosomal DNA. There are three different types of plasmids that have different functions.
Animal’s cells go through many phases when replicating DNA. One is called mitosis, which is a long complex cell cycle. In the end linear chromosomes divide and make copies of themselves with the use of various proteins and processes. The replicated strand called sister chromatids are pulled apart and then the cell divides into two with the original DNA in one and the sister chromatin and the other. Defects in mitosis can lead to many problems such as cancerous cells that continue to replicate.

During reproduction the cell also divides, but undergoes two separate divisions called meiosis. By the end of the cycle, 4 haploid cells are created. Haploid cells contain a single set of chromosomes, such as sperm and egg cells. This is where variation among all animals comes from.
