Which of the following is NOT a structural component of a typical enveloped virus particle?
A
Capsid
B
Ribosome
C
Viral genome
D
Envelope
Verified step by step guidance1
Step 1: Understand the structure of a typical enveloped virus. It generally consists of a viral genome, a capsid (protein coat), and an envelope derived from the host cell membrane.
Step 2: Identify the role of each component: the viral genome contains the genetic material; the capsid protects the genome; the envelope surrounds the capsid and helps in host cell entry.
Step 3: Recognize that ribosomes are cellular organelles responsible for protein synthesis and are not part of the virus particle structure.
Step 4: Compare each option to the known virus structure components: capsid, viral genome, and envelope are all structural parts, while ribosomes are not.
Step 5: Conclude that ribosomes are NOT a structural component of a typical enveloped virus particle.
