DNA Replication
Name_________________________
I Can:

Describe how DNA makes a copy of itself with the 3 stages: unwinding, base pairing, and joining.

Explain how the enzymes DNA helicase and DNA polymerase are involved in DNA replication.
Identify the 3 parts of a nucleotide and circle a nucleotide in
the digram:
1
2
3
Describe Chargaff’s bonding rule for nitrogenous bases:
In the diagram, label the parts of the DNA molecule including
dioxyribose (sugar), phosphate, and A/T/C/G (nitrogenous
bases).
The structure of DNA looks like a twisted ladder…what is the
term for this structure?__________________________________________
DNA is found where in the cell?_________________________________
What is the purpose of DNA replication?
Where in the cell does replication take place?________________
What is the function of helicase in DNA replication?
What is the function of DNA polymerase in DNA replication?
What is the end result of DNA replication?
Show the complimentary base pairing that would occur in the replication of the short DNA molecule
below. Use two different colored pencils (or different pens, markers, etc.) to show which strands are the
original and which are newly synthesized.
