A) Which statement best describes viral reproduction? (1 point)
Viral nucleic acid is inserted into a host cell where it may replicate immediately or become dormant until a later time.
The lysogenic phase of viral replication causes cell death while the lytic phase of viral replication results in prophage formation.
Viruses may contain DNA or RNA.
Viruses reproduce independent of cell based organisms.
The statement "Viral nucleic acid is inserted into a host cell where it may replicate immediately or become dormant until a later time" best describes viral reproduction.
The correct statement that best describes viral reproduction is: "Viral nucleic acid is inserted into a host cell where it may replicate immediately or become dormant until a later time."
To determine which statement best describes viral reproduction, we need to evaluate each option.
A) Viral nucleic acid is inserted into a host cell where it may replicate immediately or become dormant until a later time.
This statement describes the process of viral replication called the lysogenic cycle. During this phase, the viral nucleic acid (DNA or RNA) is integrated into the host cell's DNA and can remain dormant for an extended period before triggering replication.
B) The lysogenic phase of viral replication causes cell death while the lytic phase of viral replication results in prophage formation.
This statement is incorrect. The lysogenic phase is a period of viral replication where the viral DNA integrates into the host cell's DNA without causing immediate cell death. The lytic phase, on the other hand, is when the virus replicates within the host cell, causing it to burst and release new viral particles.
C) Viruses may contain DNA or RNA.
This statement is true. Viruses can contain either DNA or RNA as their genetic material, but not both.
D) Viruses reproduce independent of cell-based organisms.
This statement correctly describes viral reproduction. Unlike cell-based organisms, viruses cannot reproduce on their own. They require a host cell to provide the necessary cellular machinery and resources for replication.
Based on the explanations provided, the correct answer is D) Viruses reproduce independent of cell-based organisms.
