Which of the following best describes the structure of a viral capsid in organic chemistry?
A
A nucleic acid sequence that forms the viral genome
B
A lipid bilayer that surrounds the viral genome
C
A protein shell that encases the viral genome
D
A carbohydrate matrix that protects the viral genome
Verified step by step guidance1
Understand the role of a viral capsid: In virology, the capsid is the protein shell that encases and protects the viral genome, which can be either DNA or RNA.
Differentiate between the options: A nucleic acid sequence refers to the genetic material itself, not the protective structure. A lipid bilayer is typically associated with viral envelopes, not capsids. A carbohydrate matrix is not a common structural component of viruses.
Recognize the composition of a capsid: Capsids are primarily composed of protein subunits called capsomeres, which assemble to form the protective shell around the viral genome.
Consider the function of the capsid: The capsid not only protects the viral genetic material but also plays a role in the attachment and entry of the virus into host cells.
Conclude with the correct description: Based on the structure and function, the best description of a viral capsid is 'A protein shell that encases the viral genome.'
