BIMM 120 CH 11

What does the capsid of the T4 phage have?

linear dsDNA genome
What is the tail of the T4 phage composed of?

Sheath and internal tube
How many base pairs are in a T4 genome? Proteins?

169kbp and 289 proteins
What do the early genes of the lytic phage do?
- They are transcribed by the host RNA polymerase
- produces DNase and DNA polymerase
How are T4 genomes synthesized?

Rolling-circle replication
What do the late genes of the lytic phage do?
- capsid
- tail proteins
- lysozyme to lyse cell and release mature phages
Process of adsorption
- tail fibers contact outer membrane of host
- conformational change causes sheath to contract and inject genome
What are the three pathways for T4 assembly?
- Tail
- Head
- Tail fibers
How are phage mutations discovered?
- conditional lethal mutations
- ex. temperature sensitive mutants
