Which part of mitosis shows the sister chromatids lined up in the middle?

Sister chromatids line up at the metaphase plate. The kinetochore becomes attached to the mitotic spindle.

Which phase of mitosis has sister chromatids lining up?

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 meiosis are sister chromatids lined up in the middle of the cell?

During prophase II, sister chromatids align at the center of the cell in singular chromosome structures. These sister chromatids are separated during anaphase II, resulting in a total of four haploid cells.

What is interphase mitosis?

Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells. The prefix inter- means between, so interphase takes place between one mitotic (M) phase and the next.

Do sister chromatids separate in mitosis or meiosis?

The two sister chromatids are separated from each other into two different cells during mitosis or during the second division of meiosis. Compare sister chromatids to homologous chromosomes, which are the two different copies of a chromosome that diploid organisms (like humans) inherit, one from each parent.

During which phase of mitosis do chromosomes line up at the spindle equator quizlet?

Spindle fibers attach to the paired homologous chromosomes. The paired chromosomes line up along the equator of the cell. This occurs only in metaphase I. In metaphase of mitosis and meiosis II, it is sister chromatids that line up along the equator of the cell.

What happens during mitosis?

During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. … Then, at a critical point during interphase (called the S phase), the cell duplicates its chromosomes and ensures its systems are ready for cell division.

What happens during metaphase II?

During metaphase II, the centromeres of the paired chromatids align along the equatorial plate in both cells. Then in anaphase II, the chromosomes separate at the centromeres. The spindle fibers pull the separated chromosomes toward each pole of the cell. … Cytokinesis follows, dividing the cytoplasm of the two cells.

What is the middle stage of interphase?

Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth). At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.

What is prophase in mitosis?

Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses.

How do sister chromatids move through mitosis?

Anaphase. During anaphase, sister chromatids separate and move to the spindle poles (Figures 2 and 3). Anaphase consists of two phases, anaphase A and B.

How are the sister chromatids separated from each other?

The sister chromatids are pairs of identical copies of DNA joined at a point called the centromere. … The sister chromatids are separated simultaneously at their centromeres. The separated chromosomes are then pulled by the spindle to opposite poles of the cell.
