What else can I help you with?
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 directly after metaphase?
Anaphase
What happens after pro-phase?
Metaphase
Describes what happens during metaphase?
Chromosomes align along equator, or metaphase pate of cell.
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 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 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?
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.
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?
Mitosis for sure has metaphase. Scientists are guessing that meiosis has it too, but they combine it and make it "prometaphase," because prophase and metaphase happens so fast in meiosis.
What happens directly after prophase?
Metaphase
What metaphase does nondisjunction occur in Metaphase 1 or metaphase 2?
Non-disjunction is the failure of a pair of chromosomes or chromatids to separate. Since this happens in both metaphase I and II, non-disjunction can occur in either stage.In metaphase I it is the failure of the two homologous chromosomes in the pair to separate. In this case all of the gametes will be affected.In metaphase II it is the failure of the two sister chromatids to separate. In this case only half of the gametes are affected.Non-disjunction is the cause of a number of genetic conditions eg Down syndrome, Triple-X syndrome.See http://en.wikipedia.org/wiki/Nondisjunction
