1. Replication
-The main purpose of replication is to produce more exact copies of DNA so that new cells also have DNA to function properly
-It begins when enzymes start unzipping the double helix to separate the two strands
-The separation of the DNA strands make a “replication bubble”.

2. Replication -Each strand acts as a template to form a daughter strand
-Daughter strands are
formed when enzymes
add new nucleotides to
the bases of the
nucleotides on the
parental strands
-semiconservative replication – one parental strand is conserved and joins with a new strand to form the new double helix

3. Replication
-The DNA strands continue to unwind and replicate as the replication bubble expands, and the two forks move in opposite directions
-At each fork, there is a single, continuous “leading” strand, and another “lagging” strand made of a series of short fragments that are subsequently repaired and ligated together.
