is made using
information from
DNA;

10. ONJECTIVES
1. Identify the steps of DNA
replication.
2. Simulate DNA
replication.
3. Show importance of DNA
replication.

11. PRESENTATION
Students are group into 3,
and base on the materials
given, let them perform the
task given by following the
instruction given.

12. PRESENTATION Steps of DNA replication
1. Unzipping
2. Base Pairing
3. Joining

13. PRESENTATION Steps of DNA replication
1. Unzipping- is the separation of the
two DNA strands that make up the helix
that forms letterY.
2. Base Pairing- match the
complementary base pair to the expose
the DNA strand.
3. Joining- connect the
complementary base pair and seal it.

14. EVALUATION Group Activity
Each group is task to draw a
ray diagram showing image
formed in a concave mirror and
describe the image formed.
After 10 minutes the group will
post their work on the board
and describe the image formed.

18. GENERALIZATION Importance of DNA replication
•It ensure that all body cell must carry
the same genetic material and that
instructions are copied exactly for the
next generation.
•Occurs the S phase or synthesis stage
of the interphase,
