DNA ReplicationDuring replication, the molecule splits into two strands

Each half serves as a template to make a new, whole molecule

When we make a new strand, we call it the complimentary strand!

Step 1DNA Helicase (an ENZYME!) “unzips” DNA

down the middle

Step 2New bases are laid down according to the

patter on each side of the split DNA strand. The job of DNA Polymerase is to add new

nucleotides to the DNA!

Step 3Each new strand of DNA is “zipped” back up.

You now have two strands of DNA, each containing one piece of the old DNA and one piece of the new DNA
