Question

11. Enveloped viruses such as HIV and influenza leave the cell by a process called A. Reverse transcription B. de-integration C.reverse Osmosis D. budding E. endocytosis 12. Microbe X is easily ingested by phagocytes while Microbe Y is not. What might you assume about Microbe X? A. Xis motile B.X makes spores C. X has LPS D. X lacks a capsule

Answer 1

11. Some viruses have envelopes which is a layer that protects their genetic material in host body. Viruses such as HIV and influenza leave the cell by a process called Budding. Nucleocapsid helps form a membrane which forms a bud and is pinched off in the extracellular space.

12. Microbe X which is easily ingested by phagocytes may lack a capsule. Capsule helps in making the bacterial surface slippery and inhibits its attachment to molecular patern recognition receptors on phagocytes. Hence, if the bacteria is missing a capsule, it will be more vulnerable to Phagocytes.
