  2. United Nations Staff Selection System - Wikipedia

    en.wikipedia.org/wiki/United_Nations_Staff...

    [1]: section 3.1 and 3.2 The intent of the new system is to integrate "recruitment, placement, promotion and mobility of staff within the Secretariat" up to and including D-1 and equivalent posts. [ 1 ] : section 2.1 The new system introduces a new requirement of periodic 'mobility' for promotion for "Staff in the Professional and above ...

  3. Restriction point - Wikipedia

    en.wikipedia.org/wiki/Restriction_point

    Steps of the cell cycle. The restriction point occurs between the G 1 and S phases of interphase.. The restriction point (R), also known as the Start or G 1 /S checkpoint, is a cell cycle checkpoint in the G 1 phase of the animal cell cycle at which the cell becomes "committed" to the cell cycle, and after which extracellular signals are no longer required to stimulate proliferation. [1]

  4. G1 phase - Wikipedia

    en.wikipedia.org/wiki/G1_phase

    The G 1 phase, gap 1 phase, or growth 1 phase, is the first of four phases of the cell cycle that takes place in eukaryotic cell division. In this part of interphase , the cell synthesizes mRNA and proteins in preparation for subsequent steps leading to mitosis.

  5. G1/S transition - Wikipedia

    en.wikipedia.org/wiki/G1/S_transition

    The G1/S transition is a stage in the cell cycle at the boundary between the G1 phase, in which the cell grows, and the S phase, during which DNA is replicated. [1] It is governed by cell cycle checkpoints to ensure cell cycle integrity and the subsequent S phase can pause in response to improperly or partially replicated DNA. [2]

  6. Cell cycle checkpoint - Wikipedia

    en.wikipedia.org/wiki/Cell_cycle_checkpoint

    In eukaryotes, the cell cycle consists of four main stages: G 1, during which a cell is metabolically active and continuously grows; S phase, during which DNA replication takes place; G 2, during which cell growth continues and the cell synthesizes various proteins in preparation for division; and the M phase, during which the duplicated ...

  7. Cell cycle - Wikipedia

    en.wikipedia.org/wiki/Cell_cycle

    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.

  8. S phase - Wikipedia

    en.wikipedia.org/wiki/S_phase

    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 and widely conserved.

  9. Personnel selection - Wikipedia

    en.wikipedia.org/wiki/Personnel_selection

    Personnel selection is the methodical process used to hire (or, less commonly, promote) individuals.Although the term can apply to all aspects of the process (recruitment, selection, hiring, onboarding, acculturation, etc.) the most common meaning focuses on the selection of workers.
