pairs of homologous chromosomes move to the equator of the cell
during metaphase 0_______0
Both cyclin A and Cdk remain undegraded
Metaphase 1 looks like a group of bivalents. This is because the spindle fibers get aligned and arranged via a bipolar attraction. They end up along the equatorial line.
Metaphase is the phase of cell division where chromosomes line up on the equator of the cell just prior to splitting to the poles at anaphase. During mitosis identical chromosomes pair up on the equator, wheras during meiosis the homologous pairs line up together during meiosis 1 and then homologous chromatids line up together in meiosis 2.
There is no stage between metaphase and anaphase. Mitosis has four stages, first its prophase then metaphase then anaphase then telophase.
This is when the chromosomes become new ones.
This happens during metaphase. I remember this phase because it is the move phaseof mitosis. The m from move matches the m from metaphase.In mitosis, it happens during metaphase.In meiosis, it happens twice and occurs in metaphase 1 and metaphase 2.
Metaphase
Metaphase
Anaphase
meiosis (anaphase II)
1. In metaphase 1 spindle formation is completed In metaphase 2 spindle formation take place 2. Bivalent are involved in metaphase 1 Bivalents are not involved in metsphase 2
Chromosomes align along equator, or metaphase pate of cell.
Metaphase 1 The chromosomes line up on the equatorial (metaphase) plate. Metaphase 2 Kinetochores of the paired chromatids.
Metaphase 1
the cell becomes haploid
It is during the anaphase of meiosis that the replicated homologous chromosomes line up next to each other at the cell's equator.
