Questions and Answers
- 1.
A virus is constructed to two components which are genome and _____________?
Explanation
A virus is composed of two main components, its genome and proteins. The genome contains the genetic material of the virus, which can be either DNA or RNA. The proteins, on the other hand, play various roles in the virus's life cycle, such as facilitating entry into host cells, replicating the viral genome, and assembling new viral particles. Therefore, protein is the correct answer to complete the given statement.Rate this question:

Viruses that infect only bacteria are called?
Correct Answer
bacteriophagesExplanation
Bacteriophages are viruses that specifically infect bacteria. They are composed of a protein coat that encapsulates their genetic material. Bacteriophages attach to the surface of bacteria and inject their genetic material into the host cell. Once inside, the phage takes control of the bacterial machinery to replicate its own genetic material and produce more phages. Eventually, the host cell is destroyed, releasing new phages to infect other bacteria. Bacteriophages have been extensively studied and have shown potential in various applications, such as bacterial control in medical and industrial settings.Rate this question:

Viruses that infect only fungi are called?
Correct Answer
mycophagesExplanation
Mycophages are viruses that specifically infect fungi. The term "myco" refers to fungi, while "phages" means to eat or devour. Therefore, mycophages are viruses that "devour" or infect fungi. This term is used to distinguish these viruses from other types of viruses that infect different organisms.Rate this question:

An intact infectious virus particle is called a?
Correct Answer
virionExplanation
A complete and infectious virus particle is referred to as a "virion." A virion consists of the virus's genetic material, either DNA or RNA, enclosed within a protein coat called a capsid. It is the fully formed and functional form of a virus that is capable of infecting host cells and replicating itself. The term "virion" is often used to distinguish the complete infectious particle from other forms of the virus, such as viral components or particles that are not capable of causing infection on their own.Rate this question:
- 7.
The single protein subunits that form a viral capsid is called?
Correct Answer
capsomeresExplanation
Capsomeres are the individual protein subunits that come together to form the viral capsid. The capsid is the outer protein coat of a virus that protects the genetic material inside. Each capsomere is made up of multiple protein molecules that assemble in a precise pattern to create the overall structure of the capsid. These capsomeres can vary in size and shape depending on the type of virus. Understanding the composition and arrangement of capsomeres is important in studying the structure and function of viruses.Rate this question:
- 8.
Enveloped viruses get their envelopes from hot cell membranes by budding?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Enveloped viruses acquire their envelopes by budding from the host cell membranes. During the budding process, the newly formed virus particles push through the host cell membrane, obtaining a portion of it as their envelope. This envelope is derived from the host cell's lipid bilayer, which surrounds and protects the viral genetic material. Therefore, it is correct to say that enveloped viruses get their envelopes from host cell membranes through the budding mechanism.Rate this question:

Mumps is transmitted through airborne droplets from the coughs and sneezes of infected people?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Mumps is indeed transmitted through airborne droplets from the coughs and sneezes of infected people. When an infected person coughs or sneezes, tiny droplets containing the mumps virus are released into the air. These droplets can then be inhaled by others nearby, leading to the spread of the virus. Therefore, it is important to take precautions such as covering the mouth and nose when coughing or sneezing, and practicing good hygiene to prevent the transmission of mumps.Rate this question:
