Lysis

Answer 18

The physical rupture or deterioration of a cell

Prions

Answer 28

A concocted Word to denote “ Proteinaceous infectious agent”

Question 29

Prophage

Answer 29

A lysogenized bacterial phase; a phase that is latentlyly incorporated into the host chromosome instead of undergoing viral replication and license

Question 30

Release

Spikes

Answer 31

A receptor on the surface of certain envelope viruses that facilitate specific attachment to the host cell

Syncytia

Answer 32

A multi nucleated protoplasmamic mass formed by consolidation of individual cells

Question 33

Synthesis

Question 34

Temperate phages

Answer 34

A bacterial phage that enters into a less virulent state by becoming incorporated into the host genome as a prophage instead of in the vegetative or lytic form that eventually destroys the cell
