Which of the following is a parameter used in the Baltimore classification model for viruses?
A
Host cell type (prokaryotic or eukaryotic)
B
Presence of a lipid envelope
C
Type of nucleic acid (DNA or RNA)
D
Shape of the capsid
Verified step by step guidance1
Understand that the Baltimore classification system categorizes viruses based on their genetic material and replication strategy.
Identify that the key parameter in this system is the type of nucleic acid the virus contains, which can be DNA or RNA, and whether it is single-stranded or double-stranded.
Recognize that other options like host cell type, presence of a lipid envelope, and capsid shape are important for virus characterization but are not used in the Baltimore classification.
Recall that the Baltimore classification divides viruses into seven groups based on their genome type and how they produce mRNA.
Conclude that the correct parameter used in the Baltimore classification is the 'Type of nucleic acid (DNA or RNA)'.
