Critical Analysis of DNA Replication in Bacteria

DNA replication is a biological process that occurs in all living organisms and copies their DNA; it is the basis for natural inheritance. The process starts when one double-stranded DNA molecule produces two identical copies of the molecule. The cell cycle (mitosis) also pertains to the DNA replication/reproduction process. DNA replication, in eukaryotes, is controlled… View Article
