Front 4

Single-stranded RNA viruses, that have multipartite genomes:

Back 4

1-orthomyxoviruses (6,7,8)

2-bunyaviruses (3 segments)

3-arenaviruses (2 segments)

Front 5

Viral genomic RNA, if it is ofthe same sense as mRNA , & it can direct synthesis of protein it said to be _

Back 5

Positive sense

Front 6

Viral genomic RNA, if the genomic nucleotide sequence is complementary to that mRNA , it said to be _

Back 6

Negative sense

Front 7

Ambisense:

Back 7

part of the RNA segment positive sense , & part negative sense

Ex:

1-arenaviruses

2-bunyaviruses

Front 8

Structural virus :

Back 8

Used to construct the capsid & other components of the virion

Ex:

1-capsid

2-capsomere

3-matrix

4-enveloped protein

Front 9

Nonstructural virus :

Back 9

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

Front 10

Viral proteins:

Back 10

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
