Frequent question: During which phase chromosomes are arranged at the poles?

What Happens during Telophase? During telophase, the chromosomes arrive at the cell poles, the mitotic spindle disassembles, and the vesicles that contain fragments of the original nuclear membrane assemble around the two sets of chromosomes.

How are chromosome arranged during this phase?

During metaphase chromosomes are arranged on a plane which is known as an equatorial plate. Metaphase is a stage in which the eukaryotic cell division takes place resulting in the alignment of chromosomes in the middle of the cell. The stages that take place before metaphase are prophase and prometaphase.

During which phase chromosomes are arranged on the equatorial plate?

Chromosomes in metaphase get arranged at the equatorial plate (see Fig. 1).

Which stage of mitosis chromosomes are present in equatorial pole?

In metaphase, the centromeres of the chromosomes convene themselves on the metaphase plate (or equatorial plate), an imaginary line that is equidistant from the two centrosome poles.

During which stage do the daughter chromosomes arrive at the poles?

Anaphase: Spindle fibers shorten, the kinetochores separate, and the chromatids (daughter chromosomes) are pulled apart and begin moving to the cell poles. Telophase: The daughter chromosomes arrive at the poles and the spindle fibers that have pulled them apart disappear.

How are the chromosomes arranged in the cell during metaphase?

During metaphase I, the homologous chromosomes are arranged in the center of the cell with the kinetochores facing opposite poles. The homologous pairs orient themselves randomly at the equator.

Which phase comes between G1 and G2?

Complete answer:

Sl.No S phase
1. S phase or synthesis phase is the second sub-phase of interphase.
2. It occurs in between the G1 (Gap 1) phase and G2 (Gap 2) phase.
3. It is the phase of the cell cycle in which DNA replication takes place.

Which protein is formed in G2 phase?

Answer: Live-cell imaging confirms that cycloheximide blocks entry into mitosis. Early studies on fixed cells showed that the protein synthesis inhibitors puromycin and cycloheximide cause cells to arrest in G2 phase (1, 2).

During which phase of the cell cycle do the chromosomes exist in double state?

In the eukaryotic cell cycle, chromosome duplication occurs during “S phase” (the phase of DNA synthesis) and chromosome segregation occurs during “M phase” (the mitosis phase).

What happens during metaphase stage?

Metaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes. These chromosomes then become visible. During this stage, the nucleus disappears and the chromosomes appear in the cytoplasm of the cell.

What is interphase G2?

G2 is the shortest phase of interphase. It is when organelles and proteins necessary for cell division are produced. The cell requires a bunch of proteins and other stuff to separate the chromosomes and divide the cell in half. All of these materials are produced during G2.

What are the stages 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.
