During late maturation, production of these steroids decreased markedly, and synthesis of 20b-hydroxypregnenone (20b-P) 20b-P were induced. P was metabolized to androstenedione and T during the early stage; during final 5/5(3).
Migratory birds fly with an intensity that is twice the maximum aerobic capacity of a running animal. Dr. Christopher Guglielmo at the University of Western Ontario will use an Early Researcher Award to investigate how birds and bats store and use body fat during demanding, long-distance flights. This page intentionally left blank Genetic Analysis There is a paradox lying at the heart of the study of heredity. To understand the ways in which features are passed on from one generation to the next, we have to dig deeper and deeper into the ultimate nature of things – from organisms, to genes, to molecules.
Discussions for such a book took initial form on the coattails of the outstanding 69th Cold Spring Harbor Symposium on Epigenetics in the summer of , but were seeded in early and formally commissioned by CSHL Press through Alex Gann and other colleagues. BIOLOGICAL OVERVIEW. The Drosophila piwi gene is required for the asymmetric division of germ-line stem cells (GSCs) that takes place during the process of gametogenesis. GSCs are the source of gametes during gametogenesis. The process may be likened to an assembly line one can follow, from the raw material of the GSCs to the egg and sperm 'finished product'.

Common to these stages is their low water content and high survivability during harsh conditions. Upon rehydration, organisms need to reactivate metabolism and protein synthesis. Plant seeds contain many mRNAs that are transcribed Cited by: 3. INTRODUCTION The changes in the activities of single s or of entire metabolic pathways which occur during of embryonic tissues have attracted the curiosity of embryologists and biochemists for many decades.

Volume V deals with the problems of turnover in the nervous system. "Turnover" is defined in different ways, and the term is used in different contexts.

Recent molecular and embryological experiments suggest that peptide growth factors and homeobox genes interact to specify cell fates and pattern during early development of this vertebrate. The division of one cell into two requires the coordination of multiple components.
We describe a gene, car-1, whose product may provide a link between disparate cellular tion of car-1 expression in Caenorhabditis elegans embryos causes late cytokinesis failures: cleavage furrows ingress but subsequently regress and the spindle.

AA Dordrecht. Although RNA metabolism has not been so intensively studied in plants the indications are that precursors to 5s RNA, tRNA and mRNA do occur.
When considering the question of the regulation of RNA metabolism, therefore, it is necessary to take account of post-transcriptional modifications as possible control points. Comparative phylogenetic analysis against vertebrate TR sequences revealed that the purple sea urchin TR contains vertebrate-like template-pseudoknot and H/ACA domains.
While lacking a vertebrate-like CR4/5 domain, sea urchin TR has a unique.
