DNA Replication

DNA replication is a process in which DNA is synthesized.   This process is necessary because every cell in living organisms must contain DNA in order to create its components and remain recognizable to the organism.  When a cell within an organism wants to reproduce, through a process known as mitosis, the cell must also be able to carry on its DNA.  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. It snips the DNA an pulls apart the double helix you guys need to mention the structure somewhere)  Once the DNA has been sniped, proteins read the cut DNA in a  specific direction and produce the compliment to the first strand.  Therefore we say the second strand is complimentary to the first. Or that the second strand will match the second in bonding pairs. Once the enzymes have finished, another enzyme DNA Ligase will re-helix the DNA and make it back into what is was before.  Now there are two sets of DNA helices  (4 DNA strands).  One of the sets will remain in the cell while the other set migrates to the new cell that is being reproduced from the original cell.
