double chromosomes first become visible in which step of mitosis?
The chromosomes become different from each other due to crossing over which occurs during prophase I.
During metaphase of mitosis, the chromosomes become attached to the spindle fibers.
Interphase as they become decondenced
Chromosomes coil up and become visible during the prophase stage of cell division. This coiling allows the chromosomes to become more condensed and easier to separate during cell division.
During the Prophase. :)Chromosomes become highly condensed.They are visible to light microscope,not naked eye
prophase
Yes, sister chromatids separate and become individual chromosomes during mitosis. This process ensures that each daughter cell receives a complete set of chromosomes.
Centromeres divide and sister chromosomes become full-fledged chromosomes during the anaphase stage of mitosis. This is when the sister chromatids are pulled apart towards opposite poles of the cell, ultimately becoming individual chromosomes.
Spindle fibers become attached to the chromosomes during prophase in the early stages of cell division.
prophase
It is called prophase
