Which is a key feature of anaphase?

In anaphase, the sister chromatids separate from each other and are pulled towards opposite ends of the cell. The protein “glue” that holds the sister chromatids together is broken down, allowing them to separate. Each is now its own chromosome. The chromosomes of each pair are pulled towards opposite ends of the cell.

What is the key event of anaphase?

The major event of Anaphase is the sister chromatids moving to opposite poles of the cells, due to the action of the condensing spindle fibres. The chromatids only start separating when the pressure is sufficient to split the centromere. At this point, each chromatid effectively becomes a chromosome.

Which of the following is a feature of anaphase?

During anaphase, each pair of chromosomes is separated into two identical, independent chromosomes. The chromosomes are separated by a structure called the mitotic spindle. … The separated chromosomes are then pulled by the spindle to opposite poles of the cell.

What is the unique feature in anaphase?

In anaphase, the paired chromosomes separate and begins to move to opposite ends of the cell.

What is the function of anaphase?

Anaphase is a very important stage of cell division. It ensures that duplicated chromosomes, or sister chromatids, separate into two equal sets. This separation of chromosomes is called disjunction. Each set of chromosomes will become part of a new cell.

What is the key feature of telophase?

The main events of telophase include a reappearance and enlargement of the nucleolus, enlargement of the daughter nuclei to their interphase size, decondensation of the chromatin resulting in a brighter appearance of the nuclei with phase-contrast optics, and a period of rapid, postmitotic nuclear migration during …

Which of the following is the key event in anaphase quizlet?

The key event in anaphase is the removal of __ proteins from the centromeres of sister chromatids. During anaphase, two forms of movement take place simultaneously and as a result sister chromatids are pulled towards opposite poles of the cell.

Which of the following are the key features of mitosis?

Mitosis is a process where a single cell divides into two identical daughter cells (cell division).

  • During mitosis one cell? divides once to form two identical cells.
  • The major purpose of mitosis is for growth and to replace worn out cells.

What does the metaphase do?

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.

Which of the following is the feature of anaphase of mitosis?

In anaphase, the sister chromatids separate from each other and are pulled towards opposite ends of the cell. The protein “glue” that holds the sister chromatids together is broken down, allowing them to separate. Each is now its own chromosome. The chromosomes of each pair are pulled towards opposite ends of the cell.

What is the main function of centromere?

The primary function of the centromere is to provide the foundation for assembly of the kinetochore, which is a protein complex essential to proper chromosomal segregation during mitosis.

Where does anaphase usually occur?

Anaphase of Meiosis takes place in the sperm and the ovum cells whereas Anaphase of Mitosis can take place in all cells of the body. In anaphase, the spindle fibres pull homologous chromosomes that are arranged at the equatorial plate, towards opposite poles of the spindle.

What is chromosome function?

The most important function of chromosomes is to carry the basic genetic material – DNA. DNA provides genetic information for various cellular functions. … Thus, chromosomes also perform the function of protecting the genetic material (DNA) from damage during the process of cell division.

What is anaphase in meiosis?

Separation occurs simultaneously at the centromere and each separated chromosome gets pulled by the spindles to the opposite poles of the cell. The function of anaphase is to ensure that each daughter cell receives identical sets of chromosomes before the final phase of the cell cycle, which is telophase.

Which occurs in anaphase quizlet?

What happens during Anaphase? The spindle fibers SPLIT APART the sister chromatids and move them to opposite ends of the cell, equally dividing the genetic material.

What is an example of anaphase?

For example, a human somatic cell has 46 chromosomes. During anaphase when the chromatids are separated and pulled to opposite poles, the cell momentarily has 92 chromosomes, because these chromatids are classified as distinct chromosomes.
