Cell replication relates to how cells reproduce and how they replicate their DNA.

Binary Fission

In binary fission the bacteria increase the cell mass slightly, replicate DNA and several other cell components.  Each cell divides equally into two cells .  This process takes place every five to ten minutes.

Conjugation

Two cells meet, form a bridge, and exchange pieces of DNA  this creates a new cell.

Mitosis

This is a continuous process that replicates chromosomes and form two nuclei.  The stages of mitosis include prophase, metaphase, anaphase, and telephase.

The last phase of mitosis

Meiosis

In Meiosis the number of chromosomes are reduced by half.  Each daughter cell is haploid.  Meiosis is the replication process used for human sexual reproduction.
