Question

AIDS virus contains
A) ssRNA with protein
B) dsRNA
C) ssDNA
D)dsDNA

Answer 1

Hint:AIDS stands for acquired immune deficiency syndrome is a disease caused by virus human immunodeficiency virus (HIV). HIV is a retrovirus that carries single-stranded RNA. RNS is present as the genetic material.

Complete answer:
>AIDS is the communicable disease.
>HIV transmitted by contaminated blood transfusions, hypodermic needles, and from mother to child during pregnancy, delivery, or breastfeeding.
>Three phases of HIV infection: acute infection, clinical latency, and AIDS
>Acute infection phase symptoms: Fever, large tender lymph nodes, throat inflammation, rash, headache, tiredness, sores of the mouth and genitals, opportunistic infections, gastrointestinal symptoms, peripheral neuropathy or Guillain–Barré syndrome.
clinical latency phase symptoms: fever, weight loss, gastrointestinal problems and muscle pains
>AIDS phase symptoms: pneumocystis pneumonia, cachexia, esophageal candidiasis and respiratory tract infections.
>HIV has a viral envelope, matrix proteins, and core. The envelope of viral consists of two layers of lipids which are immersed in the proteins. Matrix proteins are found in between envelope and core. The viral core consists of two single strands of RNA as genetic material for replication.

Hence the correct answer is option ‘A’.

Note:Retroviruses have the enzyme reverse transcriptase which helps the replication of RNA into DNA and use that DNA "copy" to infect human, or host, cells. HIV virus infects the cell by fuse with the host cell and then viral RNA is converted into DNA. It means the virus uses the host cell’s to replicate its genetic material during a process called reverse transcription. The new copies of HIV formed are released into the system of the host to increase the infection.
