during prophase
During prophase of mitosis, DNA condenses and coils into visible chromosomes. This phase marks the beginning of the cell division process, where chromosomes pair up and become more distinguishable under a microscope.
Chromosomes first appear to be double during the S phase of the cell cycle when DNA replication occurs. This results in two identical sister chromatids joined by a centromere in preparation for cell division.
During the process of mitosis, the cell begins to split the cytoplasm and daughter cells first become visible in the phase called cytokinesis. This phase follows telophase, where the nuclear envelopes re-form around the separated sets of chromosomes. Cytokinesis involves the formation of a contractile ring that pinches the cell membrane, ultimately dividing the cell into two distinct daughter cells.
Prophase is the first and longest stage of mitosis. In this stage the chromosomes become visible and the centrioles separate and move to opposite poles of the cell. Mitosis is a four stage process that creates two identical cells from one original cell.
double chromosomes first become visible in which step of mitosis?
During the Prophase. :)Chromosomes become highly condensed.They are visible to light microscope,not naked eye
Interphase as they become decondenced
in the late prophase this phenomenon occur
Chromosomes become visible in the nucleus of a cell during cell division, specifically during the prophase stage of mitosis or meiosis when the DNA condenses and coils tightly. This allows the chromosomes to be distinguished under a microscope.
They first become visible during prophase of mitosis.
Interphase and Telophase
Rod-shaped chromosomes are first visible during prophase of mitosis. At this stage, the chromosomes condense and become visible as rod-shaped structures in preparation for cell division.
The phase of cell division when duplicated chromosomes first appear is called the prophase. In prophase, the chromatin condenses into visible chromosomes, and the nuclear envelope breaks down, allowing the chromosomes to be more clearly visible.
The first clue that mitosis has begun is the condensation of genetic material into visible chromosomes. This occurs during the prophase stage of mitosis when the chromosomes become visible under a microscope.
Spindle fibers first become visible during prophase of mitosis, when the chromosomes condense and the nuclear envelope breaks down. The spindle fibers are key structures involved in aligning and separating the chromosomes during cell division.
Chromosomes first become visible during cell division, specifically during mitosis and meiosis. As the cell prepares to divide, the DNA condenses and coils tightly to form chromosomes, which can be seen under a microscope. This helps to ensure accurate distribution of genetic material to daughter cells.
