What is the alignment of chromosomes along the equatorial plate?
During metaphase II, the chromosomes align along the cell’s equatorial plate.
What chromosomes align at the equator of the cell?
During prophase, the nucleus disappears, spindle fibers form, and DNA condenses into chromosomes ( sister chromatids ). During metaphase, the sister chromatids align along the equator of the cell by attaching their centromeres to the spindle fibers.
What part of the chromosome is lined up on the plate?
chromosomes are lined up at the metaphase plate. each sister chromatid is attached to a spindle fiber originating from opposite poles.
Why do chromosomes align along the equator?
J. Cell Biol. https://doi.org/10.1083/jcb.201807228) show that chromosome alignment ensures mitotic fidelity by promoting interchromosomal compaction during anaphase. During mitosis, chromosomes align at the spindle equator to establish a metaphase plate.
Do chromosomes align at the equator in meiosis?
Meiosis II is a mitotic division of each of the haploid cells produced in meiosis I. … The chromosomes begin moving toward the equator of the cell. During metaphase II, the centromeres of the paired chromatids align along the equatorial plate in both cells.
When the chromosomes align themselves across the equator of the spindle fibers?
Week 3: Quiz
|The small water channels in the cell membrane are called:||aquaporins|
|A DNA molecule is characterized by all of the following except:||ribose sugar.|
|When the chromosomes align themselves across the equator of the spindle fibers, it is characteristic of which phase of mitosis?||Metaphase|
In which part of the cell cycle do chromosomes align along the equator quizlet?
During metaphase, the chromosomes align down the equator of the cell. In anaphase, the sister chromatids separate.
Are chromosomes aligned on the spindle?
During this multistep process, cell chromosomes condense and the spindle assembles. The duplicated chromosomes then attach to the spindle, align at the cell equator, and move apart as the spindle microtubules retreat toward opposite poles of the cell.
What part of the chromosome lies on the metaphase plate?
Tetrads or bivalents (a pair of chromosomes with four chromatids (2 originals, 2 copies) are pulled into line at what is known as the metaphase (or equatorial) plate. This plate does not actually exist but is an imaginary central line along which the chromosomes are positioned.
Where do the chromosomes align?
During metaphase, the cell’s chromosomes align themselves in the middle of the cell through a type of cellular “tug of war.” The chromosomes, which have been replicated and remain joined at a central point called the centromere, are called sister chromatids.
What stage of meiosis does the chromosomes line up at the metaphase plate?
In metaphase I, the homologous chromosomes line up at the metaphase plate. In anaphase I, the homologous chromosomes are pulled apart and move to opposite poles. Sister chromatids are not separated until meiosis II.
