DNA Replication PowerPoint Notes
DNA is the genetic material of living organisms and is located in the chromosomes of each cell.
If every organism must produce copies of itself in order to pass on genetic
information to its young before it dies, how is its DNA copied?
DNA
DNA functions in the
___________way for all organisms.
It unites us all, and at the same time, it
makes each of us unique. DNA replication is the process of a DNA molecule making a

Steps in DNA replication
Replication begins with the partial
