What structures are becoming visable as distinct bodies within the nucleus during prophase?
Chromosomes
What structure are becoming visible as distinct bodies within the nucleus during prophase?
chromosomes
What phase do chromosomes condense and form?
Chromosomes condense and form during the prophase stage of mitosis. This is when the chromatin fibers in the nucleus tighten and become visible as distinct structures through a microscope.
What is broken down during prophase?
The nucleus.
During which stage of mitosis does the nucleus break down?
The breakdown of the nucleus occurs in the prophase stage of mitosis. This is when the nuclear envelope disintegrates, allowing the chromosomes to be released into the cytoplasm for subsequent division.
In which step of mitosis is a nucleus visible?
Prophase and cytokinesis
What cellular structures move to opposite ends of the cell during prophase?
It's the CENTRIOLES and their star-like radiating structures, called asters.This is Stage 1 in Mitosis:Chromatin in the nucleus condenses to form chromosomes. The pairs of centrioles move to the opposite sides of the nucleus. Spindle fibers form a bridge between the ends of the cell. The nuclear envelope breaks down.
What phase do spindle fibers appear next to nucleus?
Prophase
The two small structures that separate and take up positions on opposite sides of the nucleus during prophase are the?
The centrosomes, which contain the centrioles in animal cells, not plant cells.
What phase of mitosis does the nuclear envelope and the nucleus disappear and a spindle forms?
The phase of mitosis where the nuclear envelope and nucleus disappear is called prophase. During prophase, the chromatin condenses into discrete chromosomes, and the spindle apparatus begins to form, facilitating the movement of chromosomes during cell division.
In what phase does chromosomes condense and become visible?
The chromosomes in a cell's nucleus are only visible during the part of the cell cycle known as prophase. Prophase is the stage of mitosis in which chromatin condensation occurs.
What structure within the nucleus disappears during prophase?
The nuclear envelope.
