Genome Organi­sation

Genome Organisation

Genome Organi­sation

Terminal Regions
Has ITRs with secondary hairpin loop structures that connect two DNA strands and contains the variable genes that are respon­sible for host cell intera­ctions
Central Regions
Conserved genes respon­sible for replic­ation and morpho­genesis

Protein

Early Gene Proteins
Inducing prolif­eration of neighb­ouring cells
 
Counte­racting host immune defences
 
Some proteins can induce a second uncoating reaction thereby releasing the viral genome from the core
 
Mediating replic­ation of the genome
 
Protiens In Replic­ation
Viral DNA polymerase
 
Helica­se-­primase
 
Uracil DNA glycos­ylase
 
Single­-st­randed DNA-bi­nding protein
 
DNA ligase
 
Holliday junction resolvase
 
Proteins In Transc­ription
RNA polymerase
 
ETF
 
Capping enzyme
 
VITF-3
 
VLTF-1, VLTF-2, VLTF-3, VLTF-4
 
Release factor Elongation factor
