TRYPANOSOMA BRUCEI ATR LINKS DNA DAMAGE SIGNALING DURING ANTIGENIC VARIATION WITH REGULATION OF RNA POLYMERASE I-TRANSCRIBED SURFACE ANTIGENS

Trypanosoma brucei ATR Links DNA Damage Signaling during Antigenic Variation with Regulation of RNA Polymerase I-Transcribed Surface Antigens

Summary: Trypanosoma brucei evades mammalian immunity by using recombination to switch its surface-expressed variant surface glycoprotein (VSG), while ensuring that only funko dab rig one of many subtelomeric multigene VSG expression sites are transcribed at a time.DNA repair activities have been implicated in the catalysis of VSG switching by reco

Benefits of extra begging fail to compensate for immunological costs in southern shrike (Lanius meridionalis) nestlings.

Theoretical models aimed at explaining the evolution of honest, informative begging signals employed by nestling birds to solicit food from their parents, require that dishonest signalers incur a net viability led cocktail smoker cost in order to prevent runaway escalation of signal intensity over evolutionary time.Previous attempts to determine su

Towards a rhetoric of cross-cultural identity

This paper explores the involvement of metaphor and allusion in the ficklewood photos discursive construction of cross-cultural identity.Cross-cultural identity is regarded as a narrative; as such it is liable to rhetorical analysis and dependent on rhetorical processes for its construction and assimilation.Metaphor is claimed to serve both as an a
