The replicator dynamic

Chromatin is a highly dynamic structure that plays an essential role in regulating all nuclear processes that utilize the DNA template including DNA repair, replication, transcription and recombination. Thus, the mechanisms by which chromatin structures are assembled and modified are questions of broad interest. This minireview will focus on two groups of proteins: (a) histone chaperones and (b) ATPdependent chromatin remodeling machines, that co-operate to assemble DNA and histone proteins into chromatin....

During DNA replication, transcription and DNA repair in eukaryotes, the cellular machineries performing these tasks need to gain access to the DNA that is packaged into chromatin in the nucleus.Chromatin is a dynamic structure thatmodulates the access of regulatory factors to the genetic material.A precise coordination and organization of events in opening and closing of the chromatin is crucial to ensure that the correct spatial and temporal epigenetic code is maintained within the eukaryotic genome....

Papillomaviruses are small DNA tumor viruses that infect mammalian hosts, with consequences from benign to cancerous lesions. The Early pro-tein 2 is the master regulator for the virus life cycle, participating in gene transcription, DNA replication, and viral episome migration.
