What chromosomes align on the spindle equator?

What chromosomes align on the spindle equator?

The correct answer: The phase of cell division in which chromosomes align on the spindle equator halfway between the spindle poles is A. metaphase.

During what phase do the chromosomes line up on the equator of the spindle?

Metaphase
Metaphase follows prophase. During metaphase, the chromosomes align in the center of the cell at the equatorial plate and the spindle fibers attach to the centromeres of the chromosomes.

During which phase of mitosis do the chromosomes align at the equator of the cell?

metaphase
As prometaphase ends and metaphase begins, the chromosomes align along the cell equator. Every chromosome has at least two microtubules extending from its kinetochore — with at least one microtubule connected to each pole.

During which stage of mitosis do chromosomes line up at the equator of the spindle apparatus group of answer choices?

The spindle fibers will move the chromosomes until they are lined up at the spindle equator. Metaphase: During metaphase, each of the 46 chromosomes line up along the center of the cell at the metaphase plate.

How do chromosomes align at the equator?

During metaphase, the kinetochore microtubules pull the sister chromatids back and forth until they align along the equator of the cell, called the equatorial plane. There is an important checkpoint in the middle of mitosis, called the metaphase checkpoint, during which the cell ensures that it is ready to divide.

What is the spindle equator?

Spindle fibers form a protein structure that divides the genetic material in a cell. During the cell division phase called metaphase, the microtubules pull the chromosomes back and forth until they align in a plane along the equator of the cell, which is called the equatorial plane.

Which stage of mitosis where the chromosomes are aligned at the center of the cell?

Metaphase. Chromosomes line up at the metaphase plate, under tension from the mitotic spindle. The two sister chromatids of each chromosome are captured by microtubules from opposite spindle poles. In metaphase, the spindle has captured all the chromosomes and lined them up at the middle of the cell, ready to divide.

During which stage of mitosis do the chromosomes become attached to the spindle at their kinetochores?

Mitosis: In Summary In prometaphase, kinetochores appear at the centromeres and mitotic spindle microtubules attach to kinetochores. In metaphase, chromosomes are lined up and each sister chromatid is attached to a spindle fiber.

Why is chromosome alignment at the spindle equator important?

The maintenance of chromosome alignment at the spindle equator during metaphase is an important step in precise chromosome segregation1,2.

How is the number of possible chromosomal orientations equal to?

T/F: The number of possible chromosomal orientations during metaphase I is equal to the number of chromosome pairs raised to the 2nd power. T/F: Each orientation of chromosomes produces gametes with the same genetic information from each parent.

When do chromosomes move to the opposite poles?

The chromatids detach from one another and become visibly separated chromosomes during Anaphase The chromosomes are moving to opposite poles during Anaphase The chromosomes have arrived at opposite poles during Anaphase The nuclear membrane reforms during Telophase

Where does separation of chromosomes occur in meiosis?

D. Separation of ________ occurs in anaphase II of meiosis. D. four haploid cells, with each chromosome consisting of a single chromatid. T/F: Replication of chromosomes occurs between meiosis I and meiosis II. In animal cells, cell division is accomplished by the formation of a cleavage furrow.
