Review the animation and answer the questions that follow to test your understanding.

1		A positive (+) strand of RNA
			A)	can not function directly as mRNA
			B)	makes a minus (–) strand of RNA which can then act as mRNA
			C)	can directly act as mRNA
			D)	must be double stranded
2		In the replication of the positive (+) sense strand of lytic RNA phage, in order to make more positive (+) strands
			A)	the (+) RNA strand must code for the synthesis of RNA polymerase (replicase)
			B)	the RNA replicase uses the (+) sense RNA as a template to make (–) strand RNA
			C)	the (–) sense strand RNA is used to make more (+) strands
			D)	all of the above
3		The negative (–) sense strand of RNA
			A)	plays no role
			B)	makes RNA replicase
			C)	is used to synthesize more + strands
			D)	acts as mRNA to make viral proteins
4		A positive sense strand lytic RNA phage attaches to the cell wall of an E. coli bacterium.
			A)	True
			B)	False
5		A phage induced lysozyme lyses the host cell releasing the newly made phage.
			A)	True
			B)	False
