So this question is about naked animal viruses.
00:09
So naked animal viruses means the type of viruses which do not have lipid layer, lipid envelope around the capsid.
00:22
So you can write it as no lipid envelope around the capsid.
00:37
To understand that, let's understand the general structure of a virus.
00:44
The viruses have genetic material, nucleic acid, wrapped in a protein covering called capsid.
00:50
So, the viral capsid is made up of capsomeres and it surrounds the nucleic acid.
00:55
And thus, the capsid and the genetic material contains collectively known as the nucleocapsid.
01:03
Now, outside the capsid is a viral envelope that is made up of lipid proteins.
01:09
A lipid -pilear viral envelope can be derived from the host cell membrane as the virus butts off to the cell.
01:21
It will look something like this...
