Metaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes. These chromosomes then become visible. During this stage, the nucleus disappears and the chromosomes appear in the cytoplasm of the cell.
At what stage during the cell cycle do individual chromosomes become visible under the light microscope?
The chromosomes become visible under a light microscope during prophase in mitosis.
Are the chromosomes visible at the interphase stage?
No , chromosomes are not visible during the Interphase of cell cycle bcoz of more water content in the nucleus. … they appear as fine thread like structures called chromatin , which condenses ( Loose water ) to form compact structures called chromosomes. Chromsomes are best visible during the Metaphase.
What three phases are individual chromosomes no longer visible?
It is during interphase, telophase, and cytokinesis that the chromosomes are no longer visible.
What are the chromosomes not visible in most cells?
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 do chromosomes become visible?
Figure 1: Chromatin condensation changes during the cell cycle. 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.
Why are chromosomes visible during 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.
When chromosomes condense and become visible they are called?
During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses. The chromatin coils and becomes increasingly compact, resulting in the formation of visible chromosomes.
Why are individual chromosomes not visible at 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.
