When any cell divides, it must first replicate itself including its DNA. If the DNA was not an exact copy, then the cell couldn't function right.

When cells divide, the new cells produced must have a full set of genes in order to function correctly. Genes are made of DNA so it is necessary to replicate (copy) the DNA before the cell divides. Cell division occurs during growth, develo...

DNA replication - Wikipedia, the free encyclopedia
DNA replication , the basis for biological inheritance, is a fundamental process occurring in all living organisms to copy their DNA. This process is "semiconservative" in that each strand of the ori...

How does DNA replicate itself? ... How does DNA replicate itself? ... Cells need to copy their DNA when they divide. This process is called DNA replication. To understand how DNA is copied, we first need to understand the structure of DNA. DNA is made of two long strands that wrap around each other to make the famous double helix.

Therefore it need to replicate some of it - that is where replication come to play. To begin, an enzyme called a restriction enzyme binds itself to a specific part of the DNA that needs to be replicated.

DNA could have evolved gradually from a simpler replicator; RNA is a likely candidate, since it can catalyze its own duplication (Jeffares et al. 1998; Leipe et al. ... DNA needs certain proteins in order to replicate. Proteins need DNA to form. Neither could have formed naturally without the other already in existence.
