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 original double-stranded DNA molecule serves as template for the reproduction of the complementary strand. Hence, following DNA replication, two identical DNA molecules have been produced from a single double-stranded DNA molecule. Cellular proofreading and error-checking mechanisms ensure near perfect fidelity for DNA replication.
Although antibiotics are known to save lives, their use also supports the evolution and spread of antibiotic-resistant strains.
DNA is a genetic material that continues to survive only through replication, either naturally or synthetically. Humans require reproduction of DNA to replace damaged or old cells, but the potential to replicate DNA in a laboratory setting can allow scientists understand the disease mechanisms or the platform to develop treatments.
