Summary Introduction
To propose a hypothesis: To identify ways to block the molecular pathway to fight HIV infection.
Concept introduction: HIV is a retrovirus having RNA as a genetic material. HIV mainly attacks the immune cells, especially CD4 cells. CD4 cells play an essential role by protecting the body from any infection. Antiretroviral therapy is a method of suppressing or preventing HIV infection using drugs, e.g., Tenofovir, Zidovudine.

PART C: CALCULATING THE DIAMETER OF THE FIELD OF VIEW (FOV)_
The field of view (FOV) is the circular area you can see when you look through the microscope. The
diameter of the field of view is different depending on which objective lens you are using. For example,
you are using the medium-power objective lens, then the area you can see is actually smaller than if you
were using the low-power objective lens. Knowing The diameter of the field of view can help you estimate
actual size of objects / cells seen through the microscope.
When the revolving nose piece is turned to the low power objective lens, a dear plastic ruler can be placed on the microscope stage (see figure 1).
Then, the coarse adjustment knob can be used to focus on the millimeter marks of the ruler making sure that one of the milimeter marks is at the left
edge of the field of view (see figure 2).
NOTE:
