• Depends on host cell of

reproduction

Multiple Choice

WHICH SAMPLE MOST LIKELY CONTAINS VIRUSES?

• SAMPLE 1

• SAMPLE 2

• SAMPLE 3

• SAMPLE 4

Multiple Choice

Where do viruses reproduce?

• Outside of a cell

• Inside of a cell

• They do not reproduce

Multiple Choice

What do viruses need to reproduce?

• they need genetic material

• They need a host cell

• They need  bacteria

• They need insulin

Viruses consist of two basic components: nucleic acid (single- or double-stranded RNA or DNA) and a protein coat, the capsid, which functions as a shell to protect the viral genome from nucleases and which during infection attaches the virion to specific receptors exposed on the prospective host cell.
