  2. DNA condensation - Wikipedia

    en.wikipedia.org/wiki/DNA_condensation

    Condensation of long double-helical DNAs is a sharp phase transition, which takes place within a narrow interval of condensing agent concentrations.[ref] Since the double helices come very closely to each other in the condensed phase, this leads to the restructuring of water molecules, which gives rise to the so-called hydration forces.[ref] To ...

  3. DNA replication - Wikipedia

    en.wikipedia.org/wiki/DNA_replication

    DNA replication is an all-or-none process; once replication begins, it proceeds to completion. Once replication is complete, it does not occur again in the same cell cycle. This is made possible by the division of initiation of the pre-replication complex. [citation needed]

  4. Prophase - Wikipedia

    en.wikipedia.org/wiki/Prophase

    DNA that was replicated in interphase is condensed from DNA strands with lengths reaching 0.7 μm down to 0.2-0.3 μm. [3] This process employs the condensin complex. [11] Condensed chromosomes consist of two sister chromatids joined at the centromere. [12]

  5. Replication timing - Wikipedia

    en.wikipedia.org/wiki/Replication_timing

    The red horizontal line represents time in S-phase, from early (top) to late (bottom). Grey data points each represent a different DNA sequence position along the length of chromosome 2 as indicated on the x axis, with more positive values on the y-axis indicating earlier replication.

  6. Biomolecular condensate - Wikipedia

    en.wikipedia.org/wiki/Biomolecular_condensate

    In biology the term 'condensation' is used much more broadly and can also refer to liquid–liquid phase separation to form colloidal emulsions or liquid crystals within cells, and liquid–solid phase separation to form gels, [1] sols, or suspensions within cells as well as liquid-to-solid phase transitions such as DNA condensation during ...

  7. G2 phase - Wikipedia

    en.wikipedia.org/wiki/G2_phase

    G 2 phase, Gap 2 phase, or Growth 2 phase, is the third subphase of interphase in the cell cycle directly preceding mitosis. It follows the successful completion of S phase, during which the cell’s DNA is replicated. G 2 phase ends with the onset of prophase, the first phase of mitosis in which the cell’s chromatin condenses into chromosomes.

  8. Interphase - Wikipedia

    en.wikipedia.org/wiki/Interphase

    Interphase is the phase of the cell cycle in which a typical cell spends most of its life. Interphase is the "daily living" or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, replicates its DNA in preparation for mitosis, and conducts other "normal" cell functions. [1]

  9. 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.
