-
attachment to the host cells
adsorption
-
entry of virions into host cells
penetration
-
What are the 5 general characteristics of replication?
- 1. adsorption
- 2. penetration
- 3. synthesis
- 4. maturation
- 5. release
-
synthesis of new nucleic acid molecules, capsid proteins and other viral components via host resources
synthesis
-
assembly of new viral components into virions
maturation
-
1. lyse host's cell wall
2. virions exit host cell
release
-
viruses that infect bacterial cells
bacteriophages
-
What are the properties of bacteriophages
- - have their genetic information in the form of DS or SS RNA or DNA
- - can be simple or complex in structure
-
suspended cells on plastic layer; multiple and spread to form sheets that are one cell thick
monolayers
-
existing culture are transferred to new containers with fresh nutrient media
subculturing
-
cells that reproduce for an extended number of generations
heLa line cell
continuous cell lines
-
used by researchers all over the world
---malignant cells with capacity for rapid reproduction
HeLa line cell
