Mature mammalian red blood cells lack nuclei, mitochondria and rough endoplasmic reticulum, they do not contain DNA and consequently, cannot divide. They also cannot synthesise RNA nor synthesise any new proteins, and consequently, have a limited lifespan. Mature red blood cells circulate for about 100–120 days in the body before they are removed by the spleen.

The enzyme known as DNA polymerase is responsible for creating DNA from nucleotide monomers. The enzyme's functions are indicated by its name, DNA polymerase. The term "DNA" refers to the fact that it generates DNA utilising nucleotides. "Polymer" signifies that the enzyme is converting monomeric nucleotides into a polymer molecule. Lastly, "ase" refers to an enzyme.
<h3>What role does DNA polymerase play ?</h3>
The primary role of DNA polymerases is to preserve the genome and guarantee that the genetic code is reliably transmitted from one generation to the next.
- The essential enzyme for replication in eukaryotes is DNA polymerase. Additional DNA polymerases are used for primer removal, repair, and proofreading.
