Cell Essay Cells, the building blocks of the human body, contain genetic information (DNA) that is passed on from parent cell to daughter cell through the cell reproduction process called cell division. When a cell divides the genetic information contained in DNA copies itself and transmits to a daughter cell through a series of processes. There are two types of cells: eukaryotic and prokaryotic and these two cell types reproduce or divide in two main ways, either Mitosis or Meiosis. Cell division can also be broken down into two reproductive categories: asexual (Mitosis) and sexual (Meiosis). (Solomon et al 2002). Every cell contains DNA, which is in fact the vital information (genetic code) needed to construct and maneuver a human body. DNA is structured into units called genes. An eukaryotic cell nucleus contains a lot of DNA and protein that get together to form a chromosome. Therefore, the chromosome is the major carrier of genetic information. All species have different numbers of chromosomes and different types of genetic codes inside these chromosomes. Human beings usually have 46 different chromosomes; other species can have as little as 2 chromosomes or as many as 200. Most species contain between 10 and 50 chromosomes.
