|
Exaples of non-structural protein: |
1-protease 2-integrase 3-reverse transcriptase |
|
Single-stranded RNA viruses - that have (monopartite )genomes : |
1-retroviruses 2-paramyxoviruses 3-rhabdoviruses 4-filoviruses 5-coronaviruses 6-arteriviruses 7-picornavieuses 8-togaviruses 9-flaviviruses |
|
Single-stranded RNA viruses, that have multipartite genomes: |
1-orthomyxoviruses (6,7,8) 2-bunyaviruses (3 segments) 3-arenaviruses (2 segments) |
|
Viral genomic RNA, if it is ofthe same sense as mRNA , & it can direct synthesis of protein it said to be _ |
Positive sense |
|
Viral genomic RNA, if the genomic nucleotide sequence is complementary to that mRNA , it said to be _ |
Negative sense |
|
Ambisense: |
part of the RNA segment positive sense , & part negative sense Ex: 1-arenaviruses 2-bunyaviruses |
|
Structural virus : |
Used to construct the capsid & other components of the virion Ex: 1-capsid 2-capsomere 3-matrix 4-enveloped protein |
|
Nonstructural virus : |
Some of these not part of mature virion , it involved in virion assembly whereas others involved in various aspects of viral replication process Ex: -replication -transcription -translation |
|
Viral proteins: |
1-replicases (e.g , DNA-dependent DNA replicases) 2-transcriptases :transcribe mRNA from viral genomic double-stranded DNA or double-stranded RNA or negative-sense singe-stranded RNA 3-unique enzymes - involve in the intergration of the DNA product of reverse transcription into the cellular chromosomal DNA |
