Best answer: What are distinguishing characteristics of prophase?

The main events of prophase are: the condensation of chromosomes, the movement of the centrosomes, the formation of the mitotic spindle, and the beginning of nucleoli break down.

What is the distinguishing feature of prophase?

During prophase, the nuclear envelope disperses, replicated chromosomes condense, and the two sister chromatids become attached at a site called the centromere. At metaphase, duplicated chromosomes become aligned in a single plane. At anaphase A, the sister chromatids separate and begin to migrate to the poles.

What is a distinguishing visible feature of prophase in mitosis?

Prophase. The chromosomes are visible, and the parent cell chromosomes were duplicated during the S phase then condense and become thousands of times more compact during prophase than they were during interphase.

What are distinguishing characteristics of interphase?

Interphase Characteristics

The most commonly known interphase characteristic is the lack of visibility of the chromosome. Chromosomes are not visible under light microscopy because their nuclear DNA is loosely arranged in chromatin fibers.

What are some distinguishing features of a cell in metaphase?

Metaphase. Chromosomes line up at the metaphase plate, under tension from the mitotic spindle. The two sister chromatids of each chromosome are captured by microtubules from opposite spindle poles. In metaphase, the spindle has captured all the chromosomes and lined them up at the middle of the cell, ready to divide.

What is a distinguishing visible feature of telophase?

What is a key distinguishing visible feature of each stage of mitosis? telophase – two nuclei visible, cell splits. Once active cell division ends, the cells will enter interphase. Explain why it is incorrect to say that these cells are “resting”.

What are the main characteristics of prophase in mitosis?

mitosis. Mitosis begins at prophase with the thickening and coiling of the chromosomes. The nucleolus, a rounded structure, shrinks and disappears. The end of prophase is marked by the beginning of the organization of a group of fibres to form a spindle and the disintegration of the nuclear membrane.

How do prophase and telophase differ?

How do prophase and telophase differ? prophase condense into tightly coiled chromosomes and telophase begin to uncoil and the spindle fibers fall apart. … They differ because binary fission starts when the bacterial chromosomes is copied.

What is the most distinguishing feature of the metaphase?

Metaphase is one of the stages of mitosis. During this stage, the chromosomes align in a specific manner that is very distinguishable from all of the other stages in mitosis.

How does cytokinesis differ in plant and animal cells?

The key difference between plant and animal cytokinesis is that in plant cells, cytokinesis occurs through the formation of a cell plate while in animal cells cytokinesis occurs through the formation of a cleavage furrow.

What is occurring within a cell that is in prophase that causes the difference in its appearance?

During prophase, the parent cell chromosomes — which were duplicated during S phase — condense and become thousands of times more compact than they were during interphase.

What are the stages of mitosis give distinguishing characteristics for each stage?

1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres 2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell) 3) Anaphase: sister chromatids are pulled to opposite poles of the cell 4) Telophase: nuclear envelope …

What is the main characteristic of telophase?

The main events of telophase include a reappearance and enlargement of the nucleolus, enlargement of the daughter nuclei to their interphase size, decondensation of the chromatin resulting in a brighter appearance of the nuclei with phase-contrast optics, and a period of rapid, postmitotic nuclear migration during …
