Which of the following is not a cell but has the ability to reproduce within a living cell?
A virus
An alga
A bacterium
A yeast
Viral activity is represented in the diagram below. Invading the host cell allows the virus to -
Obtain nutrients
Increase its size
Synthesize needed oxygen
Reproduce
The structure of a virus is simpler than the structure of a cell. Typically, a virus is composed only of -
Genetic material, a protein coat, and attachment proteins
Transfer ribonucleic acid (tRNA) and enzymes
A nucleus, a Golgi apparatus, and cytoplasm
A cytoskeleton, chloroplasts, and a mitochondrion
Like cells, viruses contain-
Genetic Material
Mitochondria
Vacuoles
Chloroplasts
Why type of cycle is represented in the diagram?
Lysogenic
Mitosis
Meiosis
Lytic
Some viruses enter cells and, rather than destroy the cell, they integrate their DNA into the host cell’s chromosome, becoming a provirus. Every cell that replicates has a copy of the virus and can be activated at any time. This describes which type of viral cycle?
Lytic
Lysogenic
Bacteriophage
Retrovirus
A photograph of a virus is shown below. The projections on the surface of the virus allows the virus to?
Most inside a host cell
Control a host cell's DNA
Attach to a host cell
Signal other viruses to infect a host cell
17. During an infection some viruses remain inside cell but do not cause symptoms of disease. The graphic depicts the –
Lytic cycle and the host cell is destroyed by rapidly reproducing viral part
Lytic cycle and the viral nucleic acid inserts into the host cell chromosome
Lysogenic cycle and the viral nucleic acid inserts into the host cell
Lysogenic cycle and the viral nucleic acid inserts into the host cell
Three things are depicted below. Genetic material would best fit into which area?
W
X
Y
Z
Viruses are able to infect cells because they share a common genetic code and are to use host cell enzymes to carry out protein synthesis. There are some structures which are unique to viruses and not found in cells. These include:
I only
II only
I and II only
II and III only
People with AIDS are unable to fight multiple infections because the virus that causes AIDS –
Attacks muscle tissue
Produces anitbodies in their blood
Kills pathogens
Weakens their immune system
The virus that causes AIDS is damaging to the body because it –
Attacks specific red blood cells
Causes an abnormally high insulin level
Prevents the normal transmission of nerve impulses
Targets cells that fight invaders
HIV causes a person to develop AIDS. HIV remains active even after extensive treatment. Immunologists believe that HIV protects itself from attack by –
Mixing with the chromosomes of host cells
Consuming the nuclei of host cells
Reproducing the mitochondria of host cells
Fusing with the vacuoles of host cells
Cold sores are caused by the herpes simplex virus type 1. A company that wants to develop antiviral drugs would study what?
The mechanism used by the virus to infect cells
How closely related the virus is to cold viruses
The metabolism of the virus
Meiosis in the virus
In order to replicate itself, a virus must first –
Absorb the nucleus of the host cell
Steal the genetic material of the host cell
Penetrate the cell membrane of a host cell
Dilute the cytoplasm of a host cell
In order to replicate itself, a virus must first –
Absorb the nucleus of the host cell
Steal the genetic material of the host cell
Penetrate the cell membrane of a host cell
Dilute the cytoplasm of a host cell
