Eventually cells need to duplicate. There are two main methods of replication, mitosis and meiosis. This tutorial will talk about mitosis.
The big idea to remember is that mitosis is the simple duplication of a cell and all of its parts. It duplicates its DNA and the two new cells (daughter cells) have the same pieces and genetic code. Two identical copies come from one original. Start with one; get two that are the same.
Metaphase, in Biology, is the second phase of cell mitosis during which the chromosome align along the center of the cell (often referred to as the metaphase plate, an imaginary line that is of equal distance from the two centrosome poles) to be pulled apart during Anaphase. The word meta comes from the Greek word μετά which means "after," referring to the order of cell division stages, as metaphase takes place after prophase.
For the chromosomes to position themselves for anaphase
Metaphase is the second stage of cell division. At the metaphase plate, sister chromatids are attached to the bundle of four to eight spindle fibers.
metaphase is the longest stage . In metaphase , centrometer firmly at pore . Chromosomes line up itself at the metaphase plate with centrometer attatch to the kinetochore microtubule .
Chromosomes bind with spindle fibers. They move to the equator of cell
In the Prophase. Nuclear envelope and nucleolus disappears.
Metaphase is the third phase of mitosis, when the chromosomes line up at the equator of the cell.
During metaphase.A trick is to remember: "M for metaphase, M for the middle of the cell". This is to remind you that at metaphase the centromeres of the chromosomes are aligned in the plane of the equator.
Paired homologous chromosomes are found at the spindle equator during metaphase. During metaphase the chromosomes line up on the plate and attach to the fully formed spindle.

Metaphase!
This is the metaphase.
In the Prophase. Nuclear envelope and nucleolus disappears.
Metaphase is the third phase of mitosis, when the chromosomes line up at the equator of the cell.
During metaphase.A trick is to remember: "M for metaphase, M for the middle of the cell". This is to remind you that at metaphase the centromeres of the chromosomes are aligned in the plane of the equator.
Metaphase 1 The chromosomes line up on the equatorial (metaphase) plate. Metaphase 2 Kinetochores of the paired chromatids.
Paired homologous chromosomes are found at the spindle equator during metaphase. During metaphase the chromosomes line up on the plate and attach to the fully formed spindle.

It is during the anaphase of meiosis that the replicated homologous chromosomes line up next to each other at the cell's equator.
It organizes the microtubules in mitosis. The microtubules move the chromosomes around the cell during mitosis, most importantly lining the chromosomes up at the metaphase plate in metaphase so that they can split up into the two daughter cells.
Mitosis is the process of cell division which involves 5 different phases. These phases include prophase, prometaphase, metaphase, anaphase and telophase. Metaphase is the phase in which the chromosomes line up in the middle of the cell.
Metaphase is one of the phases in the cellcycle
