Slalom is an alpine skiing and alpine snowboarding discipline, involving skiing between poles or gates. These are spaced more closely than those in giant slalom, super giant slalom and downhill, necessitating quicker and shorter turns. Internationally, the sport is contested at the FIS Alpine World Ski Championships, and at the Olympic Winter ...
S phase. Asymmetry in the synthesis of leading and lagging strands. S phase (Synthesis phase) is the phase of the cell cycle in which DNA is replicated, occurring between G 1 phase and G 2 phase. [1] Since accurate duplication of the genome is critical to successful cell division, the processes that occur during S-phase are tightly regulated ...
The eukaryotic cell cycle consists of four distinct phases: G 1 phase, S phase (synthesis), G 2 phase (collectively known as interphase) and M phase (mitosis and cytokinesis). M phase is itself composed of two tightly coupled processes: mitosis, in which the cell's nucleus divides, and cytokinesis, in which the cell's cytoplasm and cell membrane divides forming two daughter cells.
The G1/S transition is highly regulated by transcription factor p53 in order to halt the cell cycle when DNA is damaged. [5] It is a "point of no return" beyond which the cell is committed to dividing; in yeast this is called the Start point, and in multicellular eukaryotes it is termed the restriction point (R-Point). [2][6] If a cell passes ...
Water skiers performing at Sea World on the Gold Coast, Queensland, Australia. Water skiing (also waterskiing or water-skiing) is a surface water sport in which an individual is pulled behind a boat or a cable ski installation over a body of water, skimming the surface on two skis or one ski.
Cell cycle checkpoints are control mechanisms in the eukaryotic cell cycle which ensure its proper progression. Each checkpoint serves as a potential termination point along the cell cycle, during which the conditions of the cell are assessed, with progression through the various phases of the cell cycle occurring only when favorable conditions ...
Harris moved notably leftward in her 2020 bid for president, seeing it as the best path to the Democratic nomination. But the move failed to reflect Harris' true self, which is more center-left.
A high-speed switchable device on one path, composed of a high-voltage switch, a Pockels cell, and a Glan–Thompson prism, makes it possible to divert that path away from its ordinary destination so that path effectively comes to a dead end. With the detour in operation, nothing can reach either detector by way of that path, so there can be no ...
