True
A student draws a model of the Rhinovirus which is responsible for causing the common cold. The student states that the capsid has a similar function to the nuclear membrane found in animal cells.
According to the student's illustration, which viral structure would be responsible for this function?
Which of the following is a characteristic of viruses that distinguishes them from bacteria?
Viruses require a host cell to replicate
Viruses have a nucleus
Viruses can reproduce independently
Viruses have a cell wall
What is the primary function of a vaccine in relation to viral infections?
To kill the virus directly
To stimulate the immune system to recognize and fight the virus
To provide nutrients to the body
To act as an antibiotic
Which of the following is a common method by which viruses are transmitted between hosts?
Inhalation of clean air
Exposure to ultraviolet light
Consumption of contaminated food
Direct contact with infected individuals
Place the steps of the Lytic Cycle in the correct sequential order
Attachment
Penetration
Replication
(Synthesis)
Assembly
Release
(Lysis)
Which type of nucleic acid is NOT typically found in viruses?
Double-stranded RNA
Single-stranded DNA
Triple-stranded DNA
Double-stranded DNA
A person infected with the human immunodeficiency virus (HIV) may not have any symptoms for a period of time. During this period the virus affects the body by doing which of the following?
The virus produces toxins that weaken immune cells and prevent them from reproducing.
The virus damages immune cells while using their machinery to produce copies of itself.
The virus uses nutrients meant for immune cells to fuel its own cellular respiration.
The virus changes the identity of the nucleotides of immune cells to prevent the immune system from functioning normally.
Viruses are not organisms, instead what are they ?
pathogens
diseases
bacteria
Infectious Particles
A table comparing the characteristics of four samples is shown. Which sample most likely contains viruses?
How does the lysogenic cycle differ from the lytic cycle?
The lysogenic cycle involves integration and dormancy before synthesis, while the lytic cycle results in almost immediate viral replication and quicker cell destruction.
