Answer 1

naked

-just has a capsid

Question 2

the capsid together with the nucleic acids of a virus

Answer 2

nucleocapsid

Question 3

Which is more infectious?

naked or enveloped viruses? Why?

Answer 3

naked viruses

immune system cannot detect it as easily (more hidden)

Question 4

Difference between positive and negative sense RNA?

Answer 4

positive can act as a template right away,

positive comprises viral mRNA, which can be translated into proteins directly.
