Lab 4: Virus GENEration
INTENDED LEARNING COMPETENCIES:
At the end of the lesson, you are expected to:
 Build a tangible model of a specific virus.
INTRODUCTION
In this activity, you will build a model (tangible) virus based upon genetic information
provided to them in the lab directions. Group yourselves into 5 members. Student teams
record facts information of chosen virus and then construct the virus using inexpensive,
readily available materials.
VIRUS INFORMATION SHEET
Virus sizes and shapes
What’s a nanometer?
Viruses are so small that they are measured in nanometers, the smallest unit of
measurement in the metric system. There are 10 million nanometers in a centimeter. To
get some sense of how small nanometers are, refer to the scale below.
1,000 nanometers = 1 micrometer
1,000 micrometers = 1 millimeter
10 millimeters = 1 centimeter
10,000,000 nanometers = 1 centimeter
Some common viruses
Poliomyelitis (20-27nm)
Yellow fever (22nm-30nm)
Bacteriophage (60nm x 90nm)

Influenza (100nm) Mumps (100 nm) HIV (110 nm)
Viruses come in many shapes and sizes—all so small they are measured in nanometers
(nm). Many viruses, such as the polio virus, are shaped like an isohedron, a polyhedron
that has 20 triangular faces. Rod-shaped viruses, such as the tobacco mosaic virus, have
spiral strands of nucleic acids that run through a spiral-shaped protein coat. In this
activity, you’ll create a larger-than-life virus model.
Use the link below for your chosen virus:
Infectious Diseases - A to Z List: Department of Health (ri.gov)
List of 20 Diseases Caused By Bacteria And Viruses in Humans (healthcheckup.com)
QUESTION: What is the structure of a virus?
MATERIALS: art supplies pipe stem cleaner clay transparent tape construction paper
Virus Information Sheet drinking straws wood dowels foam balls
PROCEDURE:
1. Look over the Virus Information Sheet to review the sizes and shapes of viruses. Use
the link above or internet and library resources to find more examples of viruses.
2. Choose 1 of the viruses listed in the link to make 3-dimensional models.
3. Use the scale below to determine the relative size of your model (the virus’ overall size
and the size of its components).
1 mm = 1 nm
4. Use the clay, pipe cleaners, and other art supplies to build your models.
5. Compare your finished virus model with those created by your classmates.

Possible Procedure with the materials above mention:
Building the Virus
The virus should be constructed in such a way as to follow the general virus body plan as closely
as possible. Remember to construct your virus based on the phenotype information, NOT the
genotype. Attach hands/cillia and legs/flagella to the middle body section of the virus: the thorax

Lab 5: Recessive and Dominant Genetic Ddisorder
INTENDED LEARNING COMPETENCIES:
At the end of the lesson, you are expected to:
 Determine the genotypes, phenotypes, and percentages of
parents and children with certain traits.
INTRODUCTION
Sometimes genetic disorders are caused by mutations to normal genes. When the
mutation has been in the population for a long enough amount of time, there is a
greater chance that someone can be born with the disease.
In this activity, students will use Punnett Squares to determine the genotypes,
phenotypes, and percentages of parents and children with certain traits. Students
will learn about 2 genetic disorders determine which parents are more likely to have
a child with the disease.
Procedure: Dominant Genetic Disorder
1. Huntington’s disease is a genetic disorder that is caused by a defective DOMINANT
gene. If a person has 1 or 2 dominant genes, they have the disorder. If a person has 2
recessive genes, they are normal.
2. What letters will be used for the genotypes of Huntington’s disease?

Lab 3: Introduction to Experimental Genetics
INTENDED LEARNING COMPETENCIES:
At the end of the lesson, you are expected to:
 Culture Drosophila sp. In the traditional way.
Knowing Drosophila sp.
Drosophila spp. or the commonly known fruit flies are by far the most commonly
used animals for genetic studies. It is almost ideal from a genetic standpoint.
Q1. Give 5 reasons why fruit flies are the best animal models for genetics.
PROCEDURE: Culturing Drosophila sp.
In one clean big-mouthed transparent container, place an overly ripened banana or
any fruit that you know with high carbohydrate (readily available) content. Allow the
container to seat on an open place. After a day or so, fruit flies will be teeming on your
containers. Prepare a cloth bigger than the mouth of your container (not too big!) and
quickly cover the container. Typically, the students may use the cloth of old stockings
(they are thin and can still allow good air circulation to the setup). Use a rubber band to
seal the container. You now have your raw culture of drosophila!

Genetics
Bump the base of the container with the raw culture to collect the fruit flies below.
Remove the cover and replace it with your palm. After bumping the container and
knowing that most fruit flies are already collected below, quickly replace your palm with
another clean big-mouthed container that matches the other container. The fruit flies will
begin transferring to the other container. After which, cover the lids again quickly and
seal.
To demobilize the fruit flies for observation, refrigerate the new container with
transferred fruit flies for 5 minutes until the fruit flies are no longer moving. Pick one fruit
fly or so and observe under a stereo or dissecting microscope. Remember to close the fruit
flies and be fast in observing them. They may mobilize again after achieving homeostasis!
Q2. What are the characteristics of a male and a female fruit fly?
Q3. Segregate one male and one female and place it in a small plastic. Label it with
your names (by group from the lab 1) and submit.
Q4. Draw one male and one female fruit fly.

Shalom Class!
You are done with the Subject General Biochemistry Lab Activities 1-6.
Hoping you are able to acknowledge how great, wonderful, amazing,
marvelous, and miraculous our Lord Jesus Christ in which all the covered
lessons we had in our reading materials and learning activity sheets are
presently existing and living in our outside and inside human body; from the
smallest molecule, atom, enzymes, elements, genes, inheritance, to bigger
system, etc……. of his creation.
The set deadline for these is on May 5, 2022 but still you can submit your
outputs beyond that date. Submit your outputs thru messenger WELLAH
REYTAS as file documents or do screenshots send as photos.
Thank you for your time in reading the reading materials and working your
learning activity sheets. Keep up the good work! 
