    • G0-Phase

    It is the first phase of the cell cycle, recognized by the growth period where the chromosome gets duplicated as the cell prepares for division. Interphase happens between one cell division or mitotic (M) phase and the next. It is the longest part of the cell cycle involving three sub-phases. The typical duration of this phase is 23 hours. 1. G1-ph...

    This period is also known as the cell division phase and occurs just after the G2-phase. Here, the cell divides its genetic material (DNA) and cytoplasmto form two new cells. The M-phase involves two different critical processes that unfold in the following order: a) Mitosis or Karyokinesis It is the nuclear division period and consists of four pha...

    Some cells do not immediately enter another round of preparatory phase or interphase following the division or mitosis. Instead, they exit the G1 growth phase and enter a resting stage called G0-phase. Thus, G0 is also called the alternative phase of the cell cycle. Some cells enter the G0-phase temporarily until an outside signal triggers the onse...

  7. May 16, 2017 · Carbon Cycle Definition. The carbon cycle is the cycle by which carbon moves through our Earth’s various systems. The carbon cycle is influenced by living things, atmospheric changes, ocean chemistry, and geologic activity are all part of this cycle. The levels of carbon are at an all-time high, largely due to human activities.
