What is the purpose of DNA helicase? DNA Replication: DNA replication is the process of making two identical copies of DNA from one parent molecule. DNA replication is important because it creates the new DNA needed for cell division.
What is the purpose of DNA sequencing? What is the importance of DNA methylation? What is the importance of DNA structure in genetic engineering? Why do we do DNA sequencing? Why is the sequence of dna important? What is the importance of DNA polymerase?
