Question 3

in order for viruses to reproduce they must complete these 4 steps

Answer 3

adsorption and penetration

uncoating of virus

syn and assembly of viral products and inhibition of

host cells own dna, rna, and protein synthesis

release of virions from the host cell

Question 4

absorption and penetration of virus

Answer 4

viruses are completely internalized, capsid and nuclei acid

-by endocytosis or by fusion of the virion envelope with the host cell membrane

Question 5

transcription, translation, and replication of RNA viruses

positive strand process

Answer 5

positive stranded rna viruses

• equiv to preformed messenger RNA
• as soon as invade cell they are ready for translation
• use host cell’s ribosomal proteins and enzymes to ranslate positve RNA into RNA dependent RNA polymerase, to make neg strand copies of their RNA and also more positive strands

negative stranded rna viruses: need viral rna dependent RNA polymerase to make positive strand copy
