HAPPY FRIDAY Bellwork Bellwork: Draw and Label the viruses above using the following terms: Capsid, DNA/RNA, Envelope. THEN Bring up your bellwork so I can sign it.
KEY CONCEPT Viruses exist in a variety of shapes and sizes. Viruses differ in shape and in ways of entering host cells. Viruses have a simple structure.
Viral Replication = spreading of a virus Viruses cannot replicate or express their genes without the help of a living cell. They make the cell synthesize the ...
