00:09
So all viruses contain nucleic acid, either dna or rna, but not both, and a protein coat which encases the nucleic acid.
00:31
Some viruses are also enclosed by an envelope of fat, and protein molecules in this its infective form outside the cell a virus particle is known as viran viruses do not have any nuclei or organelles or cytoplasm like cells too so the answer of this question is cytoplasm so it is not a part of virus now move to the next part of this question.

In this we need to find out the correct option regarding a tiny circular known coding rna that are able to replicate and systematically infect plants and this is known as virus.
01:52
The smallest known pathogenic virus have been proposed to represent survivors from the rna world are more likely preceded the cellular world currently dominating the life on earth.
02:16
So the answer of this question is virus.
02:26
Now move to the next part of this question.
02:29
In this question we need to find out the correct option regarding archibacteria.
02:37
So our archaeopacteria are believed to have originated at a time when there were extreme conditions in the biosphere...
