Viruses Flashcards
Is their a viable virus in the eclipse period of the the biosynthesis phase?
No
What are the four steps in biosynthesis
Eclipse period
Early products
nucleic acid production
Late products
What are the early products of biosynthesis?
Enzymes
Assembly of new viruses or virions
Maturation
Describe the process of maturation
Combining of capsids and viral nucleic acids
The host cell ruptures releasing the newly formed viruses or the newly formed viruses push through the cell membrane
release phase
describe burst time
Attachment until lysis
Describe burst size
of new viruses released
What cycle is termed by the action of the virus integrating into the host genome
Lysogenic cycle
Where does lysogenic viruses typically integrate
same site
What kind of protein prevents the expression of viral genes?
repressor proteins
