Viruses are composed of a, proteins, rna and ribosomes.
00:06
B, single -stranded dna.
00:09
C, double -stranded dna and rna.
00:12
D, single -stranded rna.
00:14
E, rna or dna, never both.
00:17
And a protein coat.
00:18
So correct answer here is e.
00:20
So a virus has two components, but all of them have.
00:24
Nuclear acid and a protein capsid.
00:28
So this is their genetic material.
00:30
It can be rna or dna.
00:32
It can be single -stranded or double -stranded of either, but it's never a mixture of dna and rna.
00:39
So it's one or the other.
00:40
And they have a protein capsid...
