Frequent question: During which phase of mitosis do the chromosomes line up on the equator equidistant from the two spindle poles?

In metaphase, the centromeres of the chromosomes convene themselves on the metaphase plate (or equatorial plate), an imaginary line that is equidistant from the two centrosome poles.

During which phase of mitosis do the chromosomes line up on a plane equidistant from the two spindle?

During metaphase phase of mitosis the chromosomes line up on a plane equidistant from the two spindle poles. Metaphase is the third phase of mitosis, the type of cell division which takes place in the somatic cells where a parent cell divides into two diploid daughter cells.

Which cell is in the first phase of mitosis?

Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses.

What can happen if cells do not duplicate correctly?

Answer: If the cell has not properly copied its chromosomes, an enzyme called cyclin dependent kinase, or CDK, will not activate the cyclin, and the cell cycle will not proceed to the next phase. The cell will undergo cell death.

What phases of mitosis are chromosomes visible?

Mitosis has four sequential stages: prophase, metaphase, anaphase, and telophase. In prophase, each chromosome becomes condensed and more visible, and there is the breakdown of the nuclear membrane and appearance of spindle fibers. In the next phase, metaphase, the chromosomes line up along the metaphasic plate.

During which phase of mitosis do the chromosomes become distinctly visible in the microscope?

During prophase the nucleoli disappear and the chromatin fibers thicken and shorten to form discrete chromosomes visible with the light microscope. Each replicated chromosome appears as two identical chromatids joined at the centromere.

What are the phases of mitosis called?

These phases are prophase, prometaphase, metaphase, anaphase, and telophase. Cytokinesis is the final physical cell division that follows telophase, and is therefore sometimes considered a sixth phase of mitosis.

In which phase of mitosis are two new cells created?

Cytokinesis, the division of the cytoplasm to form two new cells, overlaps with the final stages of mitosis. It may start in either anaphase or telophase, depending on the cell, and finishes shortly after telophase.

Which cell is in the first phase of mitosis quizlet?

Prophase is the first phase of mitosis. It begins with the division of the centriole. 4. During which stage of mitosis do nucleoli reappear?
