What are the steps in viral replication?
|
Attachment, Entry, uncoating, replication, assembly, release
|
|
|
What is required for infection?
|
Adhesion is required for infection and is mediated by cell receptor virion binding molecules.
|
|
|
Can a cell be susceptable but not permissive?
|
Yes, a cell can have receptors to bind a virion but not have the intracellular machinery to allow the virus to replicate. So that cell would be susceptable but not permissive.
|
|
|
Regarding replication, dsDNA and ssDNA viruses both use DNA-dep DNA pol, but how do their replication cycles differ?
|
Since only dsDNA can be read by DNA polymerase, ssDNA must first be converted to double stranded DNA before the DNA polymerase can work.
|
|
|
Explain the replication strategy of gapped dsDNA.
|
Gapped DNA repaired
dsDNA transcribed to mRNA by DNA dep RNA pol mRNA uses REVERSE TRANSCRIPTASE to make DNA with gaps some mRNA is packaged |
