Question
Virus capsids are made from subunits called O envelopes O spikes O capsomeres o prophages o peplomers. QUESTION 12 All of the following is correct about treating viral diseases except O viruses are killed by the same antibiotics that kill bacteria. O many antiviral drugs block viral replication. O many antiviral drugs cause severe side effects O interferons show potential for treating and preventing viral infections. All of the choices are correct QUESTION 13 Host cells of viruses include O human and other animals. O plants and fungi. O bacteria. O protozoa and algae. O All of the choices are correct. QUESTION 14 T-even phages O include the poxviruses. O infect Escherichia coli cells O enter host cells by engulfment. O have helical capsids O All of the choices are correct QUESTION 15 All of the following are characteristics of viruses except they can be crystallized. 0 they often have a geometric capsid 0 they have a viscous fluid inside their capsids. o they can cause fatal diseases they can cause mild diseases QUESTION 16Explanation / Answer
11. capsomere are subunits of capsid which is a proteinaceous covering of nucleic acid of the virus.
12. viruses are not killed by antibiotics which kill bacteria because it acts only on bacterial metabolism not virus.
13. all of the choices are correct. there are many known viruses of humans, animals, bacteria, and plants. also, fungi, protozoans, and algae are affected by viral pathogens.
14. T even phages are also called E coli phage, thus option B is correct.
15. virus do not have viscous fluid inside capsid.
