Why are chromosomes visible only on the mitosis?
Chromosomes become visible during mitosis because they condense themselves to thick, visible strands. Regularly, they are more spread out as thin strands and therefore invisible to the eye even with a microscope.
Why are chromosomes visible during this stage?
During interphase (1), chromatin is in its least condensed state and appears loosely distributed throughout the nucleus. Chromatin condensation begins during prophase (2) and chromosomes become visible. Chromosomes remain condensed throughout the various stages of mitosis (2-5).
Are chromosomes only visible during mitosis?
During most of the cell cycle, interphase, the chromosomes are somewhat less condensed and are not visible as individual objects under the light microscope. However during cell division, mitosis, the chromosomes become highly condensed and are then visible as dark distinct bodies within the nuclei of cells.
Why chromosomes are not visible during interphase?
Even though the chromosomes have been duplicated during the DNA synthesis (S) phase, individual chromatids are not visible in late interphase because the chromosomes still exist in the form of loosely packed chromatin fibers.
Why are chromosomes not condensed during all stages?
Why is cell size limited? … Why are chromosomes not condensed during all stages of the cell cycle? Because they could become entangled, or a cell could get two copies of a chromosomes and no copies of a different one (malfunctions) How does interphase prepare a cell to divide?
Do chromosomes only form during cell division?
Chromosomes, like those shown here, must form prior to cell division, to ensure that each daughter cell receives a complete set of genetic material. Essentially, each new cell receives half of each “X-shaped” chromosome.
