Which statement is incorrect concerning animal viruses?
A
Animal viruses can be enveloped or non-enveloped.
B
Animal viruses can only infect specific host cells due to receptor compatibility.
C
Animal viruses can cause diseases ranging from mild to severe.
D
Animal viruses always integrate their genetic material into the host genome.
Verified step by step guidance1
Understand that animal viruses can be classified based on whether they have an envelope or not. Enveloped viruses have a lipid membrane, while non-enveloped viruses do not.
Recognize that animal viruses have specificity for host cells, which is determined by the compatibility of viral surface proteins with host cell receptors. This specificity limits the range of cells a virus can infect.
Acknowledge that animal viruses are capable of causing a wide spectrum of diseases, from mild infections to severe illnesses, depending on the virus and the host's immune response.
Consider the statement about viral integration: not all animal viruses integrate their genetic material into the host genome. This process is characteristic of certain viruses, like retroviruses, but not all viruses follow this pattern.
Conclude that the incorrect statement is the one claiming that animal viruses always integrate their genetic material into the host genome, as this is not a universal feature of all animal viruses.
