Simple Laboratory methods to measure cell proliferation using DNA synthesis property

Abstract

This is a mini-review on the techniques to measure proliferation of cells by estimation of DNA synthesis. This is not an exhaustive review of literature, but a bird’s eye view of a few selected articles which may provide the technical details to the readers.The nucleus of a cell occupies about 10-30% of the cells space, depends on the type of genetic material (DNA -DeoxyriboNucleic Acid). DNA is a long, double-stranded, helical molecule which carries the genetic information. Duplication of the DNA takes place by the phenomena of replication. One copy of double-stranded DNA molecule forms two double-stranded DNA molecules. DNA replication is the fundamental process used in all living organisms as it is the basis for biological inheritance. This process is known also as Mitosis in somatic cells. In Mitosis, the duplication process results in two genetically identical "daughter" cells from a single "parent" cell. The resulting double-stranded DNA molecules are identical; proof reading and error-checking mechanisms exist to ensure near perfect pair. Mitosis is divided into six phases: prophase, prometaphase, metaphase, anaphase, telophase, and cytokinesis.
