Question: Which of the following best describes what happens during mitosis?

What best describes what happens during mitosis?

Mitosis is a process where a single cell divides into two identical daughter cells (cell division). During mitosis one cell? divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.

What mainly happens during mitosis?

During mitosis, the chromosomes, which have already duplicated, condense and attach to spindle fibers that pull one copy of each chromosome to opposite sides of the cell. The result is two genetically identical daughter nuclei. … Mitosis occurs only in eukaryotic cells.

What happens in each step of mitosis?

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 happens during anaphase of mitosis?

During anaphase, each pair of chromosomes is separated into two identical, independent chromosomes. The chromosomes are separated by a structure called the mitotic spindle. … The separated chromosomes are then pulled by the spindle to opposite poles of the cell.

IT IS SURPRISING:  What triggers the completion of meiosis 2?

During which process does only mitosis occur?

Through a process known as cytokinesis, the single cell breaks apart into two identical cells, completing the reproduction.

In what type of cell would mitosis occur?

Mitosis happens in all eukaryotic cells (plants, animals, and fungi). It is the process of cell renewal and growth in a plant, animal or fungus.

What happens during anaphase quizlet?

What happens during Anaphase? The spindle fibers SPLIT APART the sister chromatids and move them to opposite ends of the cell, equally dividing the genetic material. … A new nuclear membrane forms around each new set of chromosomes, each with the same number of chromosomes as the original cell.

What is being separated during anaphase of mitosis quizlet?

Anaphase is characterized by the separation of sister chromatids.

What happens during anaphase 1 and anaphase 2?

Generally, anaphase I involve separating the chromosomes from each sister chromatid to the opposite poles still attached to the microtubules of the cell while anaphase 2 involves the actual split of the sister chromatids into single chromatids.
