Question

1. DNA Replication (10 Pts.)

Create your own strand of dsDNA being sure to indicate 3’ and 5’ ends. Tell me how DNA is replicated including how bases pair. Show me DNA replication using your strand (this can be hand drawn). What enzymes are used to actually make the new DNA? How is the DNA primed for replication? What enzyme is responsible for this? What enzyme removes the primer and fills in the gap with DNA? What enzyme covalently bonds the DNA pieces together? What is the term that describes how DNA is replicated? Hint: One new and one old strand. Be sure to indicate the original (old) and replicated (new) strands.

plz see the image for better understanding about DNA replication by Semiconservative type.
