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 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 does metaphase 1 look like?
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.
What happens in metaphase 1?
pairs of homologous chromosomes move to the equator of the cell
Do homologous chromosomes pair up during metaphase 2 as they do in metaphase 1?
No, homologous chromosomes do not pair up during metaphase 2 as they do in metaphase 1. In metaphase 2, individual chromosomes line up along the metaphase plate.
What is is the difference between metaphase 1 and 2?
Metaphase 1 The chromosomes line up on the equatorial (metaphase) plate. Metaphase 2 Kinetochores of the paired chromatids.
During what phase of meiosis do replicated homologous chromosomes line up next to each other at the cell's equator-?
It is during the anaphase of meiosis that the replicated homologous chromosomes line up next to each other at the cell's equator.
Bivalents align at metaphase plate?
Metaphase 1
During metaphase II, do homologous chromosomes pair up as in metaphase I?
No, during metaphase II of meiosis, homologous chromosomes do not pair up as they do in metaphase I. Instead, individual chromosomes line up along the metaphase plate.
How does metaphase in meiosis differ from metaphase in mitosis?
In metaphase of meiosis, homologous chromosomes line up in pairs, while in metaphase of mitosis, individual chromosomes line up singly.
Differences between metaphase 1 and metaphase 2?
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
Which phase is known as the organization phase in mitosis?
Metaphase!
What phase are the chromosomes lined up on the equatorial plate?
The chromosomes are lined up at the equatorial plate during metaphase of mitosis and metaphase II of meiosis. This alignment ensures that each chromosome is properly attached to the spindle fibers before they separate and move to opposite poles.
How many chromosomes are in metaphase?
Metaphase I or Metaphase II? In metaphase I it would have 24. In metaphase II it would have 6.
What phase is the chromosome are located at the equator of the cell?
Metaphase
What are the differences in the occurrence and significance of metaphase in meiosis compared to mitosis?
In meiosis, metaphase occurs twice (metaphase I and metaphase II) while in mitosis, it occurs only once. The significance of metaphase in meiosis is to ensure proper separation of homologous chromosomes in metaphase I and sister chromatids in metaphase II, leading to genetic diversity. In mitosis, metaphase ensures accurate alignment of chromosomes for equal distribution to daughter cells, maintaining genetic stability.
