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 does 400m look like?
400 meters is 1/4 mile.
What event occurs during metaphase?
The chromosomes attach to a spindle fiber across the equator of the cell.
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
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.
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.
Bivalents align at metaphase plate?
Metaphase 1
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.
Which letter represent metaphase 1?
The letter "D" represents metaphase 1 in meiosis. During metaphase 1, homologous chromosome pairs line up at the cell's equator.
What phase of meiosis do tetrads line up in the middle?
Metaphase 1
What is the correct order for the sequence of meiosis?
Interphase Prophase 1 Metaphase 1 Anaphase 1 Telophase 1 Cytokinesis 1 Prophase 2 Metaphase 2 Anaphase 2 Telophase 2 Cytokinesis 2
Does diploid occur during metaphase 1?
Yes, ths chromosomes remain diploid in metaphase I.
What is the activity of chromosomes in metaphase 1 of meiosis?
In Mitosis during Metaphase, the chromosomes line up on the metaphase plate, but without their homologues. In Meiosis during Metaphase I, the tetrads line up on the metaphase plate. Then it's back to double-stranded chromosomes lining up in Metaphase II. I
What are the 9 stages of meiosis?
Prophase 1 , Metaphase 1 , Anaphase 1 , Telophase 1 & Cytokinesis, Prophase 2, Metaphase 2, Anaphase 2, Telophase 2 & Cytokinesis
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
