What
is
DNA?
Deoxyribonucleic Acid
DNA is the chemical name
for the molecule that carries
genetic instructions in all
living things
Double helix strand
Found in the nucleus

 What can you infer from the video?
 What are the steps in genetic engineering
shown in the video?
 How will you differentiate classical breeding
to modern genetic engineering technique?
 Can you think of different products of
classical breeding? How about genetic
engineering?

7. What is GENETIC ENGINEERING?
✗ The simple addition, deletion, or manipulation of a
single trait in an organism to create a desired change.
✗ Artificially copying a piece of DNA from one organism
and joining this copy of DNA into the DNA of another
organism
7

8. What is classical breeding
✗ Practices focus on
the mating of
organisms with
desirable qualities.

9. What is recombinant dna?

10. Steps involved in genetic engineering
✗ ISOLATION
✗ CUTTING
✗ LIGATION AND INSERTION
✗ TRANSFORMATION
✗ EXPRESSION

11. Separation of
plasmid from
a bacterial
cell

ISOLATION

12. Restriction
enzymes act as
molecular
scissors and
cut DNA at
specific sites
called restriction
sites
12
CUTTING

13. Ligation – re-
joining cut
fragments of
DNA
and forming
artificial
recombinant
molecules
13
INSERTION AND LIGATION

14. Recombinant
DNA
introduced
into bacterial
cell

TRANSFORMATION

15. Change in the
DNA of the
host
organism

EXPRESSION

17. REMINDERS
• Answer the google form version of the activity. You will be given
one chance to answer and submit the form.
• Screen shot and attach your score before submitting your work.
Your screen shot must include your name and email add which
can be seen on the screen once your form was checked.
• If you can not attach the screen shot of your score kindly submit
the copy of your score through messenger.
• If you wish to submit your written work through messenger, write
your answers on a piece of paper. Take a photo of it and pass the
photo via messenger. Make it clear and readable.

19. PERFORMANCE
TASK 1
QUARTER3: WEEK 1

20. REMINDERS
• Create a 3D model of your GMO based on the available materials at
home.
• Write a short description of your product in a clean paper/bond paper.
• Take a picture of your product and description.
• Submit your work via google classroom.

21. ✗ Directions: The next activity is hypothetical wherein
you will be acting as a biotechnologist in your
locality who was able to create a genetically
modified organism of a certain agricultural product
that is present in your locality and was given a
chance to introduce the enhanced trait of your GMO
into a biotech fair in your province this coming year.

22. What you need:
Recyclable materials, art materials, glue, scissors
What you have to do:
1. Create a 3D model of your GMO using the available materials
(recyclable) at home.
2. Write a short description of your product which contains the following;
a. Name of your GMO (combination of the source organism and the target
organism)
b. Benefits that your GMO could provide in your locality and to the society
as well. (Max. of 5 sentences)
3. Your output will be graded using the rubrics below.
