T. brucei has a single flagellum that is present throughout the parasite and its life cycle. The flagellum has conserved and unique features. It emerges from a membrane invagination at the posterior end of the cell and remains attached to the cell body for most of its length. The flagellum...
The regions locate at the exactly start or end of chromosomes are shown in black, while the others are shown in gray. All the density tracks are calculated by the base coverage in continuous 100 kb windows. The density ranges for repeat sequences and genes are both 0 to 1, those for...
‘Causa latet, vis est notissima’ [The cause is hidden, the result is very evident], Ovidius, Metamorphoses, IV. 287. 1. Introduction Biomedical science's courses comprise studies on the reproductive systems in which gonads in all animals, including humans, are included. The male testes ...
11. For instance, the formation of clonal gametes may result from several distinct mechanisms. Clonality may be achieved by achiasmatic meiosis, as observed in hybridPoecilia formosa, which maintains oogonia ploidy
As I explained earlier, this is because, unlike animals, which have their own cognitive abilities and can suffer from physical pain, yeast does not possess any of these qualities. Furthermore, yeast isn’t killed during the fermentation process in which it’s commonly used. It actually feeds ...
further with the limited genetic knowledge acquired by 1926 and the lack of understanding of meiosis in potatoes. He also worked on the breeding of one extremely important trait that was not present in the cultivars being grown in Great Britain, nor in other European countries and North America...

The lamins are the major architectural proteins of the animal cell nucleus. Lamins line the inside of the nuclear membrane, where they provide a platform for the binding of proteins and chromatin and confer mechanical stability. They have been implicated
Although it is becoming increasingly evident that maternal starvation during pregnancy can have permanent effects on a range of physiological processes in the offspring, scant information is available about the consequence of such condition for oogenesis
Nuclear calcium is an important mediator of activity-dependent gene expression in the nervous system. It serves as a signalling end point in synapse-to-nucleus communication and activates gene programmes needed for the long-term implementation of many neuroadaptations, including memory consolidation, acq...
