Which of these features is unique to retroviruses?
A
Replication in the host cell's cytoplasm
B
Use of ribosomes for protein synthesis
C
Reverse transcription of RNA into DNA
D
Presence of a double-stranded DNA genome
Verified step by step guidance1
Understand the basic definition of a retrovirus: Retroviruses are a type of virus that have RNA as their genetic material and are known for their unique replication process.
Identify the unique feature of retroviruses: Retroviruses are characterized by their ability to reverse transcribe their RNA genome into DNA once inside a host cell.
Explain reverse transcription: This process involves the enzyme reverse transcriptase, which synthesizes complementary DNA (cDNA) from an RNA template, a hallmark of retroviral replication.
Differentiate from other features: While other viruses may replicate in the cytoplasm or use ribosomes for protein synthesis, the reverse transcription of RNA into DNA is specific to retroviruses.
Conclude with the significance: This reverse transcription process allows the viral DNA to integrate into the host's genome, which is crucial for the viral replication cycle and persistence in the host.
