Protein Synthesis, DNA Replication

Protein Synthesis, DNA Replication DNA replication is the process of copying a double-stranded DNA molecule to form two double-stranded molecules.[1][2] The process of DNA replication is a fundamental process used by all living organisms as it is the basis for biological inheritance. As each DNA strand holds the same genetic information, both strands can serve as templates for the reproduction of the opposite strand. The template strand is preserved in its entirety and the new strand is assembled from nucleotides — this process is called “semiconservative replication”. The resulting double-stranded DNA molecules are identical; proofreading and error-checking mechanisms exist to ensure near perfect fidelity.
