Chromosomes become visible during prophase. Prior to that, the chromosomes were long strands of DNA material called 'chromatin'. During Prophase, the chromatin curls up into tightly wound shapes called chromosomes.
Also, when can you see the chromosomes in a cell?
When cells are not dividing, you cannot see the chromosomes, and the nucleus looks like this photograph of a cell seen under the microscope where you can see the nuclear membrane surrounding a salmon pink area. At this stage, the chromosomes are not visible – just this mass of nuclear material called chromatin.
When the chromosomes are visible?
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).
What stage can you first see the chromosomes in mitosis?
Before mitosis starts you cannot see any chromosomes in the nucleus, however, all the DNA in the nucleus is replicated exactly. This stage is not a part of mitosis: it is called interphase (between divisions). Prophase: During prophase the chromosomes coil up.
