Difference Between Metaphase 1 and 2

Metaphase 1: Microtubules of one pole are attached to kinetochores of one of the two chromosomes facing to the same pole. Metaphase 2: Microtubules are attached to the kinetochores of the centromere on either side of a single chromosome.

What is the difference between metaphase and metaphase 2?

Describe the main difference between Metaphase 1 and Metaphase 2. In Metaphase 1, paired homologous chromosomes line up along the equator of the cell. However, in mitosis and Metaphase 2, it is sister chromatids that line up along the equator of the cell. ... At the end four cells are formed.

What is the difference between metaphase in mitosis and metaphase 2 in meiosis?

Hint: Meta means second and phase means stage, hence metaphase is the second stage of meiosis and mitosis.
...
Distinguish between metaphase of mitosis and metaphase I of meiosis.

Which statements describe differences between metaphase I and metaphase II?

The difference between metaphase 1 and metaphase 2 is that in metaphase 2 the chromosomes are arranged on a metaphase plate while in metaphase 1 the pairs of chromosomes are arranged in metaphase plate. Two centromeres where each homologous chromosome are attached to in metaphase 1.

How is metaphase 1 different from metaphase of mitosis?

During metaphase of mitosis chromosomes lie at equator with one chromatid of each chromosome connected to spindle fibers from one pole and sister chromatid connected to the opposite pole. Single metaphase plate is formed. During metaphase I homologous chromosomes lie in two parallel metaphase plates at equator.

What is metaphase II?

Metaphase II is the second stage in meiosis II. ... The cell is in metaphase II when the chromosomes align themselves along the metaphase plate through the facilitation of the spindle fibers. The spindle fibers are now attached to the two kinetochores contained in the centromere of each chromosome.

What happens during metaphase?

During metaphase, the cell's chromosomes align themselves in the middle of the cell through a type of cellular "tug of war." The chromosomes, which have been replicated and remain joined at a central point called the centromere, are called sister chromatids.

What happens in metaphase 1 in meiosis?

In metaphase I, the homologous pairs of chromosomes align on either side of the equatorial plate. Then, in anaphase I, the spindle fibers contract and pull the homologous pairs, each with two chromatids, away from each other and toward each pole of the cell. During telophase I, the chromosomes are enclosed in nuclei.

How many chromosomes are in metaphase?

A chromosome can consist of either one or two chromatids. During metaphase, there are 46 chromosomes composed of two sister chromatids each that align at the metaphase plate. Then, during anaphase, these chromatids are separated and pulled to opposite poles of the cell.

Where we can observe mitosis?

Observe the cells in the zone of cell division. Locate cells in the following phases of the cell cycle: interphase, prophase, prometaphase, metaphase, anaphase, and telophase. Note: All phases of mitosis may not be present within a single field of view.

Which are steps of mitosis select 4 options?

Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase).

What's the difference between anaphase 1 and anaphase 2?

Anaphase 1 and anaphase 2 are two phases in the meiotic division of cells which produces gametes during the sexual reproduction. The main difference between anaphase 1 and 2 is that homologous chromosomes are separated during anaphase 1 whereas sister chromatids are separated during anaphase 2.

Is the DNA replicated after meiosis I Why or why not?

Meiosis, divided into meiosis I and meiosis II, is a process in which a diploid cell divides itself into four haploid cells. Note that meiosis II immediately follows meiosis I; DNA replication does not occur after meiosis I.
