some cells
All viruses are different, but what are two parts that a virus must have?
Genetic Information (DNA or RNA)
a lipid membrane
a nucleus
a protein coat
Which statement is true?
A virus has a nucleus, but no other organelles.
A virus has a nucleus and ribosomes.
A virus has no organelles, because it has no cells, and it is non-living.
Once a virus gets into a cell, it
Releases its DNA or RNA into the cell.
It begins to create DNA or RNA in the cell.
It destroys its own DNA and RNA in the cell.
What happens after the virus has been taken up by the cell?
it begins making protein
it divides, or replicates
it inserts into the host DNA
it switches to infectious mode
Why do viruses need a host cell?
because they aren't living
because they need to reproduce
because they can't live without a host cell
What is the outside, protein coat on a virus called?
genetic material
capsid
envelope
tail fibers
The more classification levels that two organisms share,
the closer together on earth they live.
the easier it is to tell them apart.
the more related they become because of many shared characteristics.
the more distance is between them due to lack of shared characteristics.
