Quick Answer: What is the phase of cell division when the replicated chromosomes line up in single file at the equatorial plate?

The correct answer: The phase of mitosis in which the chromosomes line up on the equator of the cell is e. metaphase.

During which phase do chromosomes line up in a single file line?

That’s what happens to chromosomes during prophase: they get pressed together into tight packages. In the third step of mitosis, called metaphase, each chromosome lines up in a single file line at the center of the cell.

Which phase of mitosis do chromosomes line up in?

During metaphase, the cell’s chromosomes align themselves in the middle of the cell through a type of cellular “tug of war.” The chromosomes, which have been replicated and remain joined at a central point called the centromere, are called sister chromatids.

In what phase of mitosis will you find that the sister chromatids line up single file along the equator of cell?

In animal cells, thecentrioles near the nucleus begin to separate and move to opposite poles (sides) of the cell. As the centrioles move, a spindle starts to form between them. The spindle, shown in Figurebelow, consists of fibers made of microtubules. Spindle.

During which phase of meiosis do the chromosomes line up single file in the middle of cell?

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 happens during the G1 phase?

G1 phase. G1 is an intermediate phase occupying the time between the end of cell division in mitosis and the beginning of DNA replication during S phase. During this time, the cell grows in preparation for DNA replication, and certain intracellular components, such as the centrosomes undergo replication.

During which phase do chromosomes replicate?

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).

During which stage of cell cycle do the replicated chromosomes lineup on the equator of the cell?

The correct answer: The phase of mitosis in which the chromosomes line up on the equator of the cell is e. metaphase.

What is metaphase of mitosis?

Metaphase is a stage during the process of cell division (mitosis or meiosis). Usually, individual chromosomes cannot be observed in the cell nucleus. However, during metaphase of mitosis or meiosis the chromosomes condense and become distinguishable as they align in the center of the dividing cell.

What is mitosis write metaphase stage?

A stage of mitosis in the eukaryotic cell cycle in which chromosomes are at their second-most condensed and coiled stage is known as metaphase. Carrying genetic information, aligned in the equator of the cell before being separated into each of the two daughter cells is being done with these chromosomes.

Which are replicated during interphase?

During interphase, the cell grows and DNA is replicated. During the mitotic phase, the replicated DNA and cytoplasmic contents are separated, and the cell divides.

In which phase are the condensed chromosomes or sister chromatids attached to the spindle?

Prophase: the nuclear envelope breaks down, chromosomes condense, and spindle fibers connect to sister chromatids. Metaphase: spindle fibers pull sister chromatids to the metaphase plate at the equator of the cell. Anaphase: spindle fibers separate sister chromatids to opposite poles of the cell.

During which phase of mitosis do the sister chromatids separate?

Metaphase leads to anaphase, during which each chromosome’s sister chromatids separate and move to opposite poles of the cell. Enzymatic breakdown of cohesin — which linked the sister chromatids together during prophase — causes this separation to occur.

During which phase of mitosis are the replicated chromosome aligned in the middle of the cell quizlet?

Metaphase occurs in the middle of mitosis, when the chromosomes line up in the middle of the cell. The sister chromatids separate and begin moving toward opposite poles of the cell during which phase of mitosis? Sister chromatids separate and start their migration toward opposite poles during anaphase.

What are the 4 stages of the cell cycle?

In eukaryotes, the cell cycle consists of four discrete phases: G1, S, G2, and M. The S or synthesis phase is when DNA replication occurs, and the M or mitosis phase is when the cell actually divides. The other two phases — G1 and G2, the so-called gap phases — are less dramatic but equally important.

What are the stages of meiosis division?

In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.
