Embryonic Expression Of Pre-Initiation Dna Replication Factors In Xenopus Laevis, Brian Walter, Jonathan Henry
Embryonic Expression Of Pre-Initiation Dna Replication Factors In Xenopus Laevis, Brian Walter, Jonathan Henry
Brian Walter
We examined the expression of various DNA replication factors, including: cdc45, the factors of the GINS heterotetramer (Sld5, Psf1, Psf2, Psf3), and PCNA, in Xenopus laevis during embryonic development via whole mount in situ hybridization. For the most part, these factors were expressed in similar patterns, with some subtle variations, throughout development within the anterior CNS, pharyngeal arches, and various placodes. More significant variations were also observed, including expression of only Psf1 and Psf2 in the pronephros and unique Psf2 expression in the somitic mesoderm. Overall, these results suggest that common regulatory mechanisms are involved in the transcriptional deployment of …

Peace & Well Being For All, Emmanuel Ohene Afoakwa
Professor Emmanuel Ohene Afoakwa
Peace is not only the absence of armed conflict, it is also a dynamic set of relationships of coexistence and co-operation among and within peoples, characterized by respect for human values and concern to provide the greatest possible well-being for all.

This is only possible in a world in which the observance of international law …
