In which stage of mitosis do the identical sets of chromosomes line up along the midline or equator of the cell?
In metaphase the condensed chromosomes align in a plane across the equator of the mitotic spindle.
What phase of mitosis is the identical?
The correct answer is C) telophase. In telophase, the chromatids assemble on opposite sides of the dividing cell.
In which stage of mitosis do the identical sets of chromosomes line up along the midline or equator of the cell quizlet?
Metaphase. During metaphase, spindle fibers attach to the centromere of each pair of sister chromatids (see Figure below). The sister chromatids line up at the equator, or center, of the cell. This is also known as the metaphase plate.
How would mitosis be affected if a cell was missing microtubules quizlet?
The mitotic spindle is formed of microtubules. Microtubules are polymers of the protein tubulin; therefore, it is the mitotic spindle that is disrupted by these drugs. Without a functional mitotic spindle, the chromosomes will not be sorted or separated during mitosis. The cell will arrest in mitosis and die.
In which stage of mitosis do the identical sets of chromosomes line up along the midline or equator of the cell prophase anaphase telophase metaphase?
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. Anaphase: During anaphase, the centromere splits, allowing the sister chromatids to separate.
What are the 4 phases of mitosis and what happens in each?
There are four stages of mitosis: prophase, metaphase, anaphase and telophase.1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres 2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell) 3) Anaphase: sister …
What is the S phase in cell cycle?
S phase is the period of wholesale DNA synthesis during which the cell replicates its genetic content; a normal diploid somatic cell with a 2N complement of DNA at the beginning of S phase acquires a 4N complement of DNA at its end.
In what phase of mitosis are the chromosomes aligned along the equator of the cell quizlet?
The chromosomes are aligned along the equator of the cell during metaphase. The purpose of lining up chromosomes along the metaphase plate is to ensure that chromosomes are evenly divided between the two daughter cells.
During what phase of cell division do chromosomes align along the midline quizlet?
Mitosis is the process of cell division, and is separated into four stages. During prophase, the chromosomes condense and the nuclear envelope dissolves. During metaphase, the chromosomes align at the center of the cell. During anaphase, the sister chromatids are separated and pulled to opposite ends of the cell.
