In order to answer this question, let's talk about viruses.
00:03
It says in viruses, all of the following are associated with reproduction except option a says each virus forms a protein, a protein code using its own genetic machinery.
00:14
And this is false.
00:16
Okay, because remember that viruses are not considered living organisms.
00:21
And this is why because they cannot, they are not able to reproduce if they are not, or if they don't use another cells or a cell, organelles to replicate or to get produced.
00:35
So practically, a virus is practically made of only dna or rna and protein.
00:41
So they don't have organelles.
00:42
They don't have a gybozoom.
00:43
They don't have a nucleus.
00:44
They don't have any organelles.
00:46
So they cannot divide by themselves.
00:48
This is why they have to infect cells in order to use those cells to replicate their genome and hence produce multiple more viruses.
00:58
So in this case, option a says, each virus forms a protein code using its own genetic machinery, and this is false, okay? because once they infect a cell, they are going to use the cells go offendergalyptychulum, the cells, the cells ribosomes in order to produce the viral proteins that they have to use and that they are going to have.
01:21
Okay, so option a is false.
01:23
Option b says a virus binds to a host cell.
01:27
This is true.
01:28
The cell that is going to be infected by the virus is called the host cell...
