SQUAMATION AND ECOLOGY OF THELODONTS.

Squamation and ecology of thelodonts.

Thelodonts are an enigmatic group of Paleozoic jawless vertebrates that have been well studied from taxonomical, biostratigraphic and paleogeographic points of view, although our knowledge of their ecology and mode of life is still scant.Their bodies were covered by micrometric scales whose morphology, histology and the developmental process are ex

Probing the HIV-1 genomic RNA trafficking pathway and dimerization by genetic recombination and single virion analyses.

Once transcribed, the nascent full-length RNA of HIV-1 must travel to the appropriate host cell sites to be translated or to find a partner RNA for copackaging to form newly generated viruses.In this report, we sought to delineate the location where HIV-1 RNA initiates dimerization and the influence of the RNA transport pathway used by guerlain ide
