Phenomena in biology

Research purposes: To define cause-effect relationship of genetic phenomena in living organisms, to determine the structure of cognitive competence on genetic phenomena, thereby to apply cause-effect relationship on teaching genetics to develop cognitive competence on the regularity of genetic phenomena for students, contributing to improving the quality of acquiring knowledge of this subject.

In the absence of serglycin proteoglycans, connective tissue-type mast cells fail to assemble mature metachromatic secretory granules, and this is accompanied by a markedly reduced ability to store neutral proteases. However, the mechanisms behind these phenomena are not known.

One of the most obscure phenomena in modern biology is the near genome-wide displacement of histones that occurs during the postmeiotic phases of spermatogenesis in many species. Here we review the literature to show that, during spermatogenic differentiation, three major molecular mechanisms come together to ‘prepare’ the nucleosomes for facilitated disassembly and histone removal.
