B. Recall: (15 minutes)
To recall the previous topic, the teacher will ask the following questions:
1.
Who are the people behind the discovery of DNA Structure?
2.
What are the 3 compositions of a nucleotides?
3.
What are the nitrogenous bases of DNA? RNA?
4.
What are the enzymes involved in the DNA replication?
C. Motivation: (15 minutes)
Find the pairs of each word on the flip box.

 ANALYSIS (20 minutes)
1. What is protein synthesis?
-it is a process in which cells make proteins
2. What are the 2 stages or steps of protein synthesis?
-Stage 1: Transcription, Stage 2: Translation
3. Where do transcription process happens? How about translation process?
-Transcription: Nucleus, Translation: Cytoplasm (Ribosomes)
4. What are the 3 types of RNA involved protein synthesis? What are their roles?
-mRNA (messenger RNA): carries genetic code from DNA in a nucleus to ribosome
-rRNA (ribosomal RNA): form the core of a cell's ribosomes. The site of protein-making process.
-tRNA (transfer RNA): it matches an mRNA codon with the amino acid it codes for.
5. What is a Codon? Anticodon?
- A codon is a trinucleotide sequence of DNA or RNA nucleotides that corresponds with a specific
amino acid while anticodon is also a trinucleotide sequence complementary to a corresponding
codon in mRNA.
 ABSTRACTION (25 minutes)
Game Activity: Label the Protein synthesis diagram

 APPLICATION (5 minutes)
Why our body need proteins?
Every cell in the human body contains protein. The basic structure of protein is a chain of amino
acids. You need protein in your diet to help your body repair cells and make new ones. Protein is
also important for growth and development in children, teens, and pregnant women.
What will happen in our body if we lack protein?
Serious protein deficiency can cause swelling, fatty liver, skin degeneration, increase the severity
of infections and stunt growth in children. Kwashiorkor, also known as “edematous
malnutrition” because of its association with edema (fluid retention), is a nutritional disorder
most often seen in regions experiencing famine. It is a form of malnutrition caused by a lack of
protein in the diet.
