Frequent question: What comes first prophase or prometaphase?

What are the 5 stages of mitosis in order?

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.

Is prometaphase part of prophase or metaphase?

It takes place after prophase and preceding metaphase of a dividing eukaryotic cell. However, prometaphase is sometimes considered as part of the prophase, particularly towards the end and prior to metaphase. During this stage, the nuclear membrane breaks down and forms numerous membrane vesicles.

What happens in prometaphase of mitosis?

Prometaphase is the second 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 prometaphase, the physical barrier that encloses the nucleus, called the nuclear envelope, breaks down.

What is the 1st phase of mitosis?

Prophase is the first stage in mitosis, occurring after the conclusion of the G2 portion of interphase. 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.

Which of the following events occur during prophase of mitosis?

The correct answer is (c) synapsis and crossing over. During prophase I of meiosis, synapsis and crossing over take place.

What are the 4 stages of mitosis and what happens in each?

There are four stages of mitosis: prophase, metaphase, anaphase and telophase.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 …
