3. Review

In the previous lesson, you have learned about
DNA replication which is the process of DNA
duplication from an existing DNA. The replication
of DNA is important for the growth repair and
reproduction of cells of an organism. The major key
players in DNA replication are the enzymes (Students listen)
helicase, primase, DNA polymerase and ligase.
Helicase is the unzipping enzyme and unzips the
two strands of DNA in the double helix through the
hydrogen bond that holds the two base pairs
together. Primase will initialize the process and
directs the DNA polymerase for it to figure out
where it gets to start. This primer is the starting
point for DNA synthesis. The primers are made of
RNA (Ribonucleic Acid).
B. Motivation
Group the students into two small groups and let
them do the activity.
Instruction:
Look closely at the structure of DNA and RNA.
Make a table for the summary of the similarities and
differences of DNA and RNA.
5 (minutes)
C. Lesson proper
The next lesson will help you understand how a
DNA is transcribed into RNA. RNA (Ribonucleic
Acid), unlike the double stranded DNA, is a nucleic (Students listen)
acid polymer with a single strand. It is composed of
the four nucleotides adenine, uracil, guanine and
cytosine which are represented by their first letter
A, U, G, C.
“What nucleotide is replaced by uracil in RNA”
“Verry good!”
Below is a short summary of the difference
between DNA and RNA.

“Okay, so after DNA Replication, the next step in
protein synthesis would be the transcription of DNA
to form an RNA.
Transcription in protein synthesis is the process
where RNA is made from the DNA by copying the
“Thymine Maam”
base sequence of the double stranded DNA into a
piece of a single stranded nucleic acid. This
transcription process is catalyzed by the enzyme
RNA Polymerase.
RNA falls into three major categories:
Messenger RNA (mRNA), Transfer RNA
(tRNA) and Ribosomal RNA (rRNA).
1-mRNA copies the genetic code from the
DNA into a form that can be read and used to
make proteins. mRNA transmits genetic
information from the nucleus to the
cell’s cytoplasm.
“Where do you think does trancription happens?”
“Very Good!”
“In the Nucleus Maam”
Transcription of DNA to form RNA takes place in
the cell’s nucleus.
“Why do you think Transcription is important ?”
“It is important for proper
RNA is the first intermediate in converting the cellular function.”
information from the DNA into proteins which is
important for proper cellular function.
2- rRNA is situated in the cytoplasm of a cell,
where we can find the ribosomes. rRNA leads
the translation of mRNA into proteins.
3- tRNA transfers amino acids to the ribosome
that matches to each three-nucleotide codon of
rRNA.
The amino acids then can be combined
together and processed to make polypeptides
and proteins.
