Human immunodeficiency virus (HIV), the virus that causes AIDS, is unique because its main genetic instructions are in the form of RNA instead of DNA. Because of this, it’s called a(n) (A) . When a person is infected with HIV, the immune system mounts a normal response, but soon the adaptive immune response cannot keep up with the billion new viruses being built each day inside of (B) cells.

Question

Human immunodeficiency virus (HIV), the virus that causes AIDS, is unique because its main genetic instructions are in the form of RNA instead of DNA. Because of this, it’s called a(n) (A) . When a person is infected with HIV, the immune system mounts a normal response, but soon the adaptive immune response cannot keep up with the billion new viruses being built each day inside of (B) cells.

(A)
Retrovirus
(B)

Need help on the last part of this problem

Answer 1

(B) T cells

Answer 2

To complete the last part of the problem, we need to determine the specific type of cells in which the billion new viruses are being built each day.

HIV primarily infects and replicates within immune cells called CD4+ T cells. Upon entry into the body, HIV targets these cells, enters them, and integrates its genetic material (RNA) into the DNA of the infected cell. From there, the virus uses the cellular machinery to replicate and produce more HIV particles.

Therefore, the correct answer for (B) is CD4+ T cells. These are important cells of the immune system that play a crucial role in coordinating the immune response against pathogens. When HIV infects and destroys CD4+ T cells, it weakens the immune system, making the individual more susceptible to infections and diseases.
