Double branded DNA viruses select only one answer all insert
Solution
The double-stranded DNA viruses are unique pathogens which require a DNA intermediate for replication of new viral particles using reverse transcriptase enzyme. These viruses are particularly shown to be highly active pathogens for human and higher vertebrate infections from primitive times. They are less common than RNA viruses. However, like other RNA/DNA viruses, they too possess high mutation rates owing to faulty replication and lack of proof-reading by polymeraes. Importantly, as a mode of infection, all of these viruses do insert their genome or a part of it in the host cell\'s genome to promotes its transcription and translation. This is why double-stranded DNA viruses are difficult to eradicate from human/vertebrate hosts because they very easily modulate their molecular functions according to the host machinery. Some examples of diseases caused by such viruses are small pox, herpes infection etc.
Thus, the above explanations states that choice 1 is most correct.
