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 else can I help you with?
The nuclear envelope disintegrates during .?
Cellular Division.
Why telophase sometimes described as reverse prophase?
Telophase is often described as a "reverse prophase" because it involves the re-establishment of the nuclear envelope and the uncoiling of chromatin, processes that occur in the opposite order during prophase. In prophase, the chromatin condenses into distinct chromosomes and the nuclear envelope breaks down, while telophase marks the end of cell division where chromosomes decondense and the nuclear envelope reforms around each set of chromosomes. This reversal of cellular structures highlights the cyclical nature of the cell cycle.
The events of prophase seem to be opposite of those that occur during what phase?
The events of prophase in mitosis, such as condensation of chromosomes and breakdown of the nuclear envelope, are opposite to those that occur during telophase, where chromosomes decondense, and the nuclear envelope reforms.
What stage centrioles separate?
Prophase- during prophase, chromatids shorten and thicken, nucleoli disappears, spindle fibers form and centrioles in animal cells move to opposite ends.
What structures are becoming visable as distinct bodies within the nucleus during prophase?
Chromosomes
The nuclear envelope disintegrates during .?
Cellular Division.
In which phase do moving the pairs of centrioles to opposite poles?
Moving the pairs of centrioles to opposite poles occurs during the prophase stage of mitosis. This process helps to form the mitotic spindle, which is essential for ensuring accurate chromosome segregation during cell division.

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 stage centrioles separate?
Prophase- during prophase, chromatids shorten and thicken, nucleoli disappears, spindle fibers form and centrioles in animal cells move to opposite ends.
What structures are becoming visable as distinct bodies within the nucleus during prophase?
Chromosomes
What stage of mitosis do the centrioles move to opposite ends of the cell?
The centrioles move to opposite ends of the cell during the prophase stage of mitosis. This movement is essential for the formation of the mitotic spindle, which helps separate the duplicated chromosomes during cell division.
What part of the cell takes up opposite sides of the nucleus during prophase?
CENTRIOLES
What two structures disappear during prophase?
During prophase, the nuclear membrane and the nucleolus dissolve and disappear.
The phase during mitosis in which DNA separates into pairs of chromosomes is?
The phase during mitosis in which DNA separates into pairs of chromosomes is called prophase. During prophase, the chromosomes condense and become visible as distinct structures before the actual separation occurs during later stages of mitosis.
What is the DNA called during prophase?
During prophase, DNA is condensed and tightly coiled into structures called chromosomes. These chromosomes are made up of DNA and proteins and are visible under a microscope.
