The primary DNA replication enzyme, DNA Polymerase, is highly specific and works very carefully to ensure it does not make any mistakes. It also has proofreading ability where it scans back and checks the new strand to ensure it has not made any mistakes. If an error occurs, it chews out the mistaken nucleotides and replaces them with the correct sequence. Part B) Explain how mistakes are identified by DNA polymerase so that it knows when the wrong nucleotide(s) have been put in and what needs to be replaced. This enzymes does not "know" what the DNA sequence is supposed to be, so what does it look for instead and how does it know when something is wrong.
