Interphase, when they duplicate
Prophrase
During prophase, the first stage of mitosis, the chromosomes become visible as distinct structures. The nuclear envelope also now breaks down, and a spindle forms.
The phase of mitosis where the chromatin fibers duplicate and condense into visible chromosomes is Interphase. Interphase is the first stage of the cell cycle.
prophase
The first stage of mitosis when chromosomes start becoming visible in the microscope is called prophase.
Interphase and Telophase
Prophrase
During prophase, the first stage of mitosis, the chromosomes become visible as distinct structures. The nuclear envelope also now breaks down, and a spindle forms.
The phase of mitosis where the chromatin fibers duplicate and condense into visible chromosomes is Interphase. Interphase is the first stage of the cell cycle.
prophase
The first stage of mitosis when chromosomes start becoming visible in the microscope is called prophase.
During Interphase the DNA is not in the form of chromosomes. It is not until Prophase that it condenses and chromosomes become visible.
mitosis particularly prophase
The chromosomes coil up and condense during prophase
Yes duplication of chromosomes occurs during the first stage of meiosis or during prophase.
It actally spelt prophase...1. The first stage of mitosis, during which the chromosomes condense and become visible, the nuclear membrane breaks down, and the spindle apparatus forms at opposite poles of the cell.2. The first stage of meiosis, constituted by a series of events that include the thickening and coiling of the chromosomes, synapsis of homologous chromosomes, tetrad formation, and crossing over.
You can see a chromosone at all times, however they are most easily visible during mitosis, when the cell is dividing. During this process the chromosomes condense, making them more easily visible.
