Pol V directly interacts with RecA * at the 3'tip of the nucleoprotein filament; this is the site of the nascent DNA strand where Pol V restarts DNA synthesis.

The most widespread deoxyribonucleoproteins are nucleosomes, in which the component is nuclear DNA . The proteins are combined with DNA are histone ] s and protamines; resulting nucleoproteins are located in chromosomes.
43.
Like its role in DNA replication, this keeps ssDNA from binding to itself ( self-complementizing ) so that the resulting nucleoprotein filament can then be bound by Rad51 and its cofactors.

"' Influenza virus nucleoprotein ( NP ) "'is a structural protein which encapsidates the negative strand viral RNA . NP is one of the main determinants of species specificity.
45.
Initially this occurs with the formation of a positive-sense RNA ( intermediate step necessary for producing progeny ) and finally negative-sense RNA is formed which is then associated with the nucleoprotein.
46.
Professor Tao led a team of researchers to be the first to map the structure of the influenza A virus nucleoprotein to an atomic level, a feat which circulated widely in the popular press.
47.
However, nearly all plant viruses ( such as tobacco mosaic virus ) can also move directly from cell to cell, in the form of single-stranded nucleoprotein complexes, through pores called plasmodesmata.
48.
It has been discovered that the Influenza A virus accesses this host machinery via a NLS like sequence toward the N-terminus of the viral nucleoprotein that can be recognized by importin ? class proteins.
49.
This sequence occurs within the first 20 amino acid positions of the viral nucleoprotein and contains clusters of basic amino acids, much like those found in host NLS sequences and the importin ? IBB domain.
50.
The " RNA viruses " include the " negative-sense ssRNA viruses " which include the Family " Orthomyxoviridae " which contains five genera, classified by variations in nucleoprotein ( NP and M ) antigens.
