What happens in metaphase 1?
pairs of homologous chromosomes move to the equator of the cell
What is the stage between metaphase and anaphase in mitosis?
There is no stage between metaphase and anaphase. Mitosis has four stages, first its prophase then metaphase then anaphase then telophase.
What happens during metaphase in the cell division?
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.
What event occurs during metaphase?
The chromosomes attach to a spindle fiber across the equator of the cell.
During which stage of meiosis are the bivalents arranged along the equator?
During the metaphase I meiosis are the bivalents are arranged along the equator. During the prophase I of meiosis I the crossing over occurs.
What happens after pro-phase?
Metaphase
What. Happens directly after metaphase?
Anaphase
Describes what happens during metaphase?
Chromosomes align along equator, or metaphase pate of cell.
What would you expect to happen if the anaphase-promoting complex failed to ubiquitinate securin?
The cohesin complex will be destroyed, and the cell will remain in metaphase.
What happens in annaphase?
after metaphase the chromosomes rip or break in the middle after they have lined up in metaphase and start to drift to opposite sides of the nucleus
What is a metaphase?
A metaphase cell is a stage in the cell cycle. It happens when a chromosome is most highly condensed and hence it is easiest to distinguish and to study the cell.
During what phase do the chromosomes move to the center of the cell aligned on the spindle apparatus?
During metaphase of mitosis, the chromosomes move to the center of the cell and align along the metaphase plate, which is located at the midpoint between the two poles of the cell. This alignment is crucial for ensuring that each daughter cell receives an equal number of chromosomes during cell division.
What happens in metaphase 1?
pairs of homologous chromosomes move to the equator of the cell
What happens during division?
prophase, metaphase, anaphase, telophase (including cytokinesis)
Do meisosis and mitosis have metaphase?
Yes, both mitosis and meiosis have a metaphase stage. During metaphase, the chromosomes line up along the equatorial plane of the cell before dividing in mitosis or meiosis. This stage allows for equal distribution of genetic material to daughter cells.
What happens directly after prophase?
Metaphase
What metaphase does nondisjunction occur in Metaphase 1 or metaphase 2?
Nondisjunction can occur in both Metaphase 1 and Metaphase 2 of meiosis. In Metaphase 1, it results in the incorrect separation of homologous chromosomes, leading to aneuploidy in the daughter cells. In Metaphase 2, it can lead to the incorrect separation of sister chromatids, also resulting in aneuploidy.
