DNA replication

Biological process

DNA replication is the process by which a cell makes exact copies of its DNA. This process occurs in all organisms and is essential to biological inheritance, cell division, and repair of damaged tissues. DNA replication ensures that each of the newly divided daughter cells receives its own copy of each DNA molecule. DNA most commonly occurs in double-stranded form, made up of two complementary strands held together by base pairing of the nucleotides comprising each strand.
