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

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

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 are the stages in mitosis?

Today, mitosis is understood to involve five phases, based on the physical state of the chromosomes and spindle. These phases are prophase, prometaphase, metaphase, anaphase, and telophase.

What are the 4 stages of the cell cycle?

In eukaryotes, the cell cycle consists of four discrete phases: G1, S, G2, and M. The S or synthesis phase is when DNA replication occurs, and the M or mitosis phase is when the cell actually divides. The other two phases — G1 and G2, the so-called gap phases — are less dramatic but equally important.

What are the 4 stages of meiosis?

In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.

What are the stages of mitosis and meiosis?

Meiosis and mitosis both have a prophase, metaphase, anaphase, telophase and cytokinesis.

What are the 3 stages of interphase?

Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth). At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.

What are the five stages of the cell cycle?

In eukaryotes, the cell cycle consists of a long preparatory period, called interphase. Interphase is divided into G1, S, and G2 phases. The mitotic phase begins with karyokinesis (mitosis), which consists of five stages: prophase, prometaphase, metaphase, anaphase, and telophase.

What happens in the G1 phase?

G1 phase. G1 is an intermediate phase occupying the time between the end of cell division in mitosis and the beginning of DNA replication during S phase. During this time, the cell grows in preparation for DNA replication, and certain intracellular components, such as the centrosomes undergo replication.

What are the 5 stages of meiosis?

Explanation: Meiosis-I has Prophase-I, Metaphase-I, Anaphase-I and Telophase-I. Prophase-I is sub-divided into Leptotene, Zygotene, Pachytene, Diplotene and Diakinesis.

What are the 6 stages of meiosis?

There are six stages within each of the divisions, namely prophase, prometaphase, metaphase, anaphase, telophase and cytokinesis.
