BIOLOGICAL FUNCTION OF SEX? "Why is sexuality (and meiosis) so common? This is one of the important unanswered questions in biology and has been the focus of much research beginning in the latter half of the twentieth century." https://lnkd.in/exK5mn7 View in LinkedIn

LOADED OOCYTES. "In other cases, asymmetrical meiosis in females results in a large oocyte full of resources, which may favour the production of a single cell rather than four." http://biorxiv.org/content/biorxiv/early/2016/04/28/050831.full.pdf View in LinkedIn

DOMINANT QUESTION. "The mysteries of meiosis call for new developments of evolutionary theory. Overall, all these mysteries tend to have been overshadowed by the famous question of the maintenance of sex." http://biorxiv.org/content/biorxiv/early/2016/04/28/050831.full.pdf View in LinkedIn

SO ENDS this summary of Professor Denis Nobel’s thinking, as outlined in his book Dance to the Tune of Life. The central dogma of molecular biology was formulated by Francis Crick in 1958. Often stated as “DNA makes RNA and RNA makes protein”, in essence it states that once information gets into protein, it cannot get out again, and is unidirectional in flow, and information cannot flow from protein to protein or from protein to nucleic acid. Well, in the sixty years since this proposition, we have learned a lot, and the dogma has been modified. https://lnkd.in/eQDmUtj View in LinkedIn

NORMAL WITH EXCEPTIONS, of course. "Although meiosis is highly conserved in eukaryotes, deviations from the norm are ubiquitous and may provide important insights into its evolution." https://lnkd.in/e2tp_G5 View in LinkedIn

"A RECURRENT THEME in most meiosis mysteries is the impact of genetic conflicts and selfish genetic elements. As for many genomic features, their impact is probably central, but in many cases, they remain hypothetical and difficult to study directly." https://lnkd.in/e2tp_G5 View in LinkedIn

HOTSPOTS. "The localisation of recombination events differs between species. In many species, recombination occurs in localised regions known as “recombination hotspots” of around 1-2kb in length, although some species (e.g., C. elegans and Drosophila) lack well-defined hotspots." http://biorxiv.org/content/biorxiv/early/2016/04/28/050831.full.pdf View in LinkedIn
