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

1		In the attachment step of phage replication
			A)	attachment is nonspecific
			B)	carbohydrate receptors in the phage tail attach to specific receptors on the bacterial cell wall
			C)	protein fibers in the phage tail attach to specific receptors on the bacterial cell wall
			D)	phage DNA exits the protein coat and attaches to receptors on the bacterium
2		In phage replication
			A)	only the phage nucleic acid enters the bacterial cell
			B)	the whole phage particle enters the cell and the protein outer coat is removed
			C)	multiple phage particles enter the same host bacterial cell at the same time
			D)	only the phage protein enters the bacterial cell
3		The correct order of the stages for phage replication are 1= assembly 2 = attachment 3 = transcription/replication 4 = release 5 = penetration
			A)	5, 2, 3, 1, 4
			B)	2, 5, 3, 1, 4
			C)	2, 5, 1, 3, 4
			D)	5, 2, 1, 3, 4
4		Viral lysozyme digests the host cell wall, releasing the newly made phage, and lysing the host cell in the release step.
			A)	True
			B)	False
5		Viral nucleic acid is made inside the bacterium and is combined with viral protein coat already present outside.
			A)	True
			B)	False
