Medical Microbiology And Virology Quiz - Quiz

The study of microscopic life is Microbiology and the study of viruses is Virology. So, if you're having an exam on this topic this quiz might be helpful for you to score better. So,without wasting any time let's enroll into the following quiz!

Questions and Answers

1.

What encodes Nucleic acid genome?
- A.
  
  Lipid
- B.
  
  Capsid
- C.
  
  Frious
- D.
  
  Pepsin
Correct Answer
B. Capsid

Explanation
The correct answer is Capsid. Capsid is a protein coat that encloses the nucleic acid genome of a virus. It provides protection to the genetic material and helps in the transmission of the virus to host cells. Lipids are not directly involved in encoding nucleic acid genomes. Frious and Pepsin are not relevant to the encoding of nucleic acid genomes.

Defeilivirus Causes Infection.
- A.
  
  True
- B.
  
  False
- C.
  
  Maybe
- D.
  
  Inconclusive
Correct Answer
A. True

Explanation
The given statement "Defeilivirus Causes Infection" is true. This means that Defeilivirus is a type of virus that can cause an infection in individuals.

Envelope contains lipid.
- A.
  
  True
- B.
  
  False
- C.
  
  Maybe
- D.
  
  Sometimes
Correct Answer
A. True

Explanation
Lipids are a class of organic compounds that are insoluble in water but soluble in organic solvents. They are commonly found in cell membranes and play a crucial role in various biological processes. Since the statement mentions that the envelope contains lipid, it implies that lipids are present in the envelope. Therefore, the correct answer is True.

What type of agent is Virus?
- A.
  
  Microscopic
- B.
  
  Dangerous
- C.
  
  Helpful
- D.
  
  All of the above
Correct Answer
D. All of the above

Explanation
The correct answer is "All of the above" because a virus can be classified as microscopic as it cannot be seen with the naked eye. It is also considered dangerous as it can cause various diseases and infections in living organisms. Additionally, some viruses can be helpful in certain situations, such as in genetic engineering or medical research. Therefore, all three options accurately describe the nature of a virus.

What links envelope?
- A.
  
  Matrix Protein
- B.
  
  Mercury
- C.
  
  Minute
- D.
  
  Sometimes
Correct Answer
A. Matrix Protein

Explanation
Matrix protein is the correct answer because it is a term used in biology to describe a type of protein that is found in the matrix or extracellular space of cells. This protein plays a role in various cellular processes and functions, such as cell adhesion, signaling, and structural support. It is called "matrix protein" because it is found in the extracellular matrix, which is the non-cellular component that surrounds cells in tissues. The other options, such as Mercury, Minute, and Sometimes, do not have a direct or logical link to the concept of envelope or biology.

How many faces does capsid symmetry have?
- A.
  
  50
- B.
  
  40
- C.
  
  30
- D.
  
  20
Correct Answer
D. 20

Explanation
The correct answer is 20 because capsid symmetry refers to the arrangement of protein subunits that make up the outer shell of a virus. The number of faces in capsid symmetry corresponds to the number of subunits that come together to form the shell. In this case, there are 20 faces, indicating that 20 protein subunits make up the capsid symmetry.

What has equilateral triangle?
- A.
  
  Lipid
- B.
  
  Capsid
- C.
  
  Capitol
- D.
  
  Cartel
Correct Answer
B. Capsid

Explanation
The correct answer is "Capsid" because a capsid is a protein coat that surrounds and protects the genetic material of a virus. An equilateral triangle has three sides of equal length, which is unrelated to the other options provided. Lipid refers to a type of molecule, Capitol refers to a building where a legislative body meets, and Cartel refers to a group of businesses that collude to control and manipulate a market.

Rate this question:
8.

What releases virus?
- A.
  
  Showtel
- B.
  
  Cell lysis
- C.
  
  Cartal
- D.
  
  Carpool
Correct Answer
B. Cell lysis

Explanation
Cell lysis is the process by which a cell ruptures, releasing its contents including any viruses it may contain. This can occur naturally as a result of cell death or damage, or it can be induced in a laboratory setting for the purpose of studying viruses or extracting viral components. When a cell undergoes lysis, any viruses within it are released into the surrounding environment, where they can then infect other cells and continue their replication cycle. Therefore, cell lysis is the correct answer to the question of what releases viruses.

What does interaction mean?
- A.
  
  Combustion
- B.
  
  Recombination
- C.
  
  Rewire
- D.
  
  Reprieve
Correct Answer
B. Recombination

Explanation
Interaction refers to the action or process of two or more things acting upon or influencing each other. In the given options, "recombination" best represents this concept as it refers to the process of combining or rejoining separate elements or entities to form a new whole. This implies a mutual influence or interaction between the elements being combined or recombined.

What is viral persistence?
- A.
  
  Strong virus
- B.
  
  Unending occurrence
- C.
  
  Constant occurrence
- D.
  
  All of the above
Correct Answer
C. Constant occurrence

Explanation
Viral persistence refers to the continuous or constant occurrence of a virus within a host or population. It means that the virus remains present and active over a prolonged period, often without causing immediate symptoms or being completely eliminated by the immune system. This can lead to chronic infections or recurrent outbreaks, as the virus persists and replicates within the host or spreads among individuals. The term "constant occurrence" accurately reflects this concept of viral persistence.
