WebIn genetics, a chiasma (pl. chiasmata) is the point of contact, the physical link, between two (non-sister) chromatids belonging to homologous chromosomes. At a given chiasma, an exchange of genetic material can occur between both chromatids, what is called a chromosomal crossover, but this is much more frequent during meiosis than mitosis.

WebMeiosis I. Meiosis I is preceded by an interphase consisting of the G 1, S, and G 2 phases, which are very similar to the phases preceding mitosis. The G 1 phase is focused on cell growth. The S phase is when the DNA of the chromosomes is replicated. Finally, the G 2 phase is the third and final phase of interphase where the cell undergoes its ... WebJul 7, 2024 · The G1 phase is the first gap phase. S phase: The period during which DNA is synthesized. In most cells, there is a narrow window of time during which DNA is synthesized. The S stands for synthesis. G2 phase: The period after DNA synthesis has occurred but prior to the start of prophase. The cell synthesizes proteins and continues to …
WebHighlights. Non-thermal phase transition from BCC-W to HCP-W occurs at a threshold (15500 ± 500 K) of electronic temperatures. Non-thermal phase transition in tungsten is driven by the irradiation-induced change of density of states at the Fermi level. A broad peak in kinetic energy curve appears during the period of non-thermal phase transition.
