IV. PROCEDURES
Elicit: It’s s Bingo time!
Let the learners group into four. Each group will provide a
representative to get the bingo card material from the teacher.
The winning group will be asked to connect the bingo game
activity to the next topic.
A. Review/Presenting new
lesson (5 minutes)
Engage: Watch and Learn!
Let the learners watch a video of DNA simulation and allow them
to incorporate to the central dogma of molecular biology.
Video link; https://www.youtube.com/watch?v=gG7uCskUOrA
B. Establishing a purpose
of lesson (5 minutes)
Guide questions:
1. How is DNA made out of a DNA template?
2. How does the 3 enzymes, DNA helicase, polymerase and
ligase works for DNA replication?
Engage: PPT presentation!
Let the learners be familiar with the process of DNA replication
and allow them to discover the roles and function of the three
enzymes in DNA replication.
C. Presenting instances of
the new lesson (8 minutes)
D. Discussing new concepts
and practicing new skills #1
Explore: Let’s play the role!
From the learners initial group of 4, they will be tasked to execute
the function or role of the following through a role playing.

I. Evaluation (5 minutes)
Evaluate:
In a ¼ sheet of paper
Directions: Read each statement carefully and choose the letter
of the correct answer. Write the letter only.
1. Which of the products of semiconservative DNA replication?
A. Two single- stranded molecules of DNA, containing half of the
DNA of the original DNA molecule
B. Two double-stranded molecules of DNA that are identical to
each other and to the original DNA molecule
C. Four single-stranded molecules of DNA that are identical to
each other and to the original DNA molecule
D. Four double-stranded molecules of DNA that are all
genetically unique
2. When errors in DNA replication occur, the newly formed
strand can be proofread and be recognized as not being
complementary to the original strand. Which enzyme is
responsible for correcting these errors during replication?
A. DNA ligase
B. DNA polymerase
C. DNase
D. DNA helicase
3. In the process of DNA replication, what is the primary role of
DNA helicase?
A. DNA helicase detects and repairs any errors that are made by
incorrect base pairings during DNA replication.
B. DNA helicase forms phospholipids bonds between nucleotides
to form a strand of DNA
C. DNA helicase adds nucleotides to a growing DNA chain,
synthesizing a strand of DNA complementary to the template
strand
D. DNA helicase breaks the hydrogen bonds between base pairs,
separating the two strands of DNA.
4. A single strand of DNA has the following sequence:
5’- ATTGGCCATATA-3’
Reading from the 3’ - 5’ direction, state the sequence of bases
that will form on the complimentary strand.
A. CGGTTTAACGCGC
B. ATTGGGCCATATA
C. TAACCCGGTATAT
D. TCCAAAGGTCTCT
5. In DNA replication what is the primary role of DNA
polymerase?
A. DNA polymerase adds nucleotides to a growing DNA chain to
synthesize a strand of DNA complementary to the template
strand
B. DNA polymerase catalyzes the breaking of phosphodiester
bonds in the sugar- phosphate backbone; so the DNA can be
split into fragments that are ready for replication
C. DNA polymerase breaks the hydrogen bonds between base
pairs, separating the two strands of DNA that are ready for
replication
D. DNA polymerase joins RNA primers to the 5’ end of a single
strand of DNA to indicate where replication should begin
