#1
Which of the following is NOT a step in the viral replication cycle?
Translation
ExplanationTranslation is not a step in the viral replication cycle.
#2
Which enzyme is responsible for converting RNA to DNA during retroviral replication?
Reverse transcriptase
ExplanationReverse transcriptase converts RNA to DNA in retroviral replication.
#3
Which cellular organelle is often hijacked by viruses for their replication?
Nucleus
ExplanationViruses often hijack the nucleus for replication.
#4
Which of the following is NOT a method of viral entry into host cells?
Transcription
ExplanationTranscription is not a method of viral entry into host cells.
#5
Which viral replication cycle involves the integration of viral DNA into the host cell's genome?
Lysogenic cycle
ExplanationThe lysogenic cycle involves integration of viral DNA into the host cell's genome.
#6
Which viral genome type consists of single-stranded RNA that acts as a template for mRNA synthesis?
Positive-sense RNA
ExplanationPositive-sense RNA serves as a template for mRNA synthesis.
#7
Which type of virus has a viral envelope derived from the host cell membrane?
Enveloped virus
ExplanationEnveloped viruses have an envelope derived from the host cell membrane.
#8
Which viral protein is responsible for cleaving precursor viral proteins into functional components?
Protease
ExplanationProtease cleaves precursor viral proteins into functional components.
#9
Which of the following is NOT a mechanism by which viruses evade the host immune response?
Enhancing host immune response
ExplanationEnhancing host immune response is not a mechanism of viral immune evasion.
