Weekly Quiz Competition

Question 1
4 / -1

The genetic material of HIV is

A
dsDNA

B
dsRNA

C
ssDNA

D
ssRNA

Solution

HIV which causes AIDS is a retrovirus that contains single stranded RNA (SSRNA) as its genome
Question 2
4 / -1

Which one of the following statements is true?

A
Dysentery, plague and diphtheria are viral diseases

B
HIV replicates in host cell with the help of reverse transcriptase enzyme

C
The disease ringworm disappears during summer and rainy season

D
Common cold could be confirmed by Widal test

Solution

When HIV enters into the body of a person,it moves into macrophages where RNA genome of the virus replicates to form viral DNA with the help of enzyme reverse transcriptase. This viral DNA gets incorporated into cethe host cell's DNA and directs the infected cells to produce more viruses. The macrophages producing viruses, thus act as HIV enters into helper T-cells where it replicates and produces other virus. this is repeated so that the number of helper T-cells decreases in the body of the infected person. Dysentery (Bacillary) plaque and diphtheria are bacterial diseases, Ringworm appears during summer and rainy season. Widal test is used for confirmation of typhoid.
Question 3
4 / -1

AIDS is characterized by

A
decrease in the number of Killer T-cell

B
decrease in the number of suppressor T-cells

C
decrease in the number of helper T-cells

D
increase in the number of helper T-cells

Solution

AIDS is caused by HIV. When HIV enters into helper T-cells, it replicates and produces other viruses that kill the helper T-cells. Thus the number of T-cells decrease in the body of the infected person and the person starts suffering from various infections.
Question 4
4 / -1

The figure given below shows mode of action of AIDS virus. Identify steps A, B, C, D and E labelled in it.

A
A -New viral DNA intruoduced into cell, B-Viral RNA produced, C-Viral DNA incorporated into host genome, D-New viral DNA, E-New viruses produced

B
A -Viral DNA incorporated into host genome, B-Viral DNA, C-New viral RNA introduced, D-Viral RNA produced, E-New viruses produced

C
A-Viral RNA introduced, B-Viral DNA, C-Viral DNA incorporated into host genome, D-New viral RNA produced, E-New viruses produced

D
A-Viral DNA introduced, B-Viral RNA, C-Viral RNA incorporated into host genome, D-New viral DNA produced, E-New viruses produced

Solution

Reverse transcription takes place during the formation of viral genomic RNA from DNA.
Question 5
4 / -1

The abbreviation AIDS stands for

A
Acquired immuno disease syndrome

B
Acquired immuno deficiency syndrome

C
Acquired immunity determining syndrome

D
Acquired immunity delay syndrome

Solution

AIDS (Acquired immuno deficiency syndrome) is human immunodeficiency syndrome, a series of diseases caused by the human immunodeficiency virus or HIV. It may also be referred to as HIV disease or HIV infection.
Question 6
4 / -1

Which of the following is not a cause of transmission of HIV?

A
Multiple sexual partners

B
Sharing infected needles

C
Mosquito bite

D
Transfusion of contaminated blood

Solution

By mosquitoes, ticks, or other insects. Through saliva, tears, or sweat. By hugging, shaking hands, sharing toilets, sharing dishes, or closed-mouth or “social” kissing with someone who has HIV. Through other sexual activities that don't involve the exchange of body fluids (for example, touching).
Question 7
4 / -1

AIDS is widely diagnosed by

A
Widal test

B
ELISA

C
PCR

D
Chromatography

Solution

AIDS is diagnosed by ELISA (Enzyme-linked Immunosorbent Assay) test.
Question 8
4 / -1

Identity A, B, C, D and E in the below diagram of HIV virus.

A
A−RNA , B−Reverse transcriptase, C−Capsule protein coat, D−Lipid membrane, E−Envelope protein coat

B
A−RNA, B− Reverse transcriptase, C−Lipid membrane, D−Envelope protein coat, E−Capsule protein coat

C
A−Reverse transcriptase, B−Lipid membrane, C−RNA, D−Capsule protein coat, E−Envelope protein coat

D
A−RNA, B-Reverse transcriptase, C-Envelope protein coat, D−Lipid membrane, E−Capsule protein coat

Solution

HIV virus consists of a protein capsid that encloses a couple of single-stranded RNA molecules and the enzyme Reverse transcriptase which would help the virus to convert to DNA in the host cell. There is an outer envelope covering the capsid which is made up of lipids in which are embedded the envelope proteins.
Question 9
4 / -1

Which of the following is celebrated as 'World AIDS Day'?

A
31st March

B
1st March

C
1st December

D
31st December

Solution

Every year, World AIDS Day is celebrated on December 1. This day is celebrated not only to spread awareness about the disease but also to remind the people and the governments that HIV has not gone away.
Question 10
4 / -1

The human immuno deficiency virus is

A
an unenveloped, RNA genome containing retrovirus

B
an enveloped, RNA genome containing retrovirus

C
an enveloped, DNA genome containing retrovirus

D
an enveloped, RNA genome containing rheovirus

Solution

AIDS is caused by the human immunodeficiency virus (HIV), a member of a group of virus called retroviruses which have an envelope enclosing RNA genome.
