the nuclear membrane disappears during which phase of meiosis

All AP Biology Resources

During which form of mitosis do sis chromatids separate?

Possible Answers:

Telophase

Prophase

Metaphase

Anaphase

Account:

During anaphase, the third gear stage of mitosis, the spindle fibers cause sister chromatids to break unconnected, and they are subsequently moved to opposite sides of the cellular telephone.

Chromosomes condense during prophase, align during metaphase, separate during anaphase, and are relocated during telophase.

During which phase of mitosis behave chromatids digest?

Possible Answers:

Prophase

Telophase

Metaphase

Anaphase

Account:

Chromatids condense during prophase, the first stage of mitosis. This allows the abundant amount of DNA to be organized into comparatively small and tightly packed structures that can be aligned and separated later in mitosis. This also signifies the conversion of the DNA from loosely packed euchromatin to tightly packed heterochromatin.

Chromosomes digest during prophase, align during metaphase, separate during anaphase, and are relocated during telophase.

Which of the following actions occurs during telophase of mitosis?

Possible Answers:

Nuclear membranes thaw

Chromosomes aline at the center of the prison cell

Cytokinesis

The nucleolus dissolves

Slump suffice:

Cytokinesis

Account:

Cytokinesis, the sue of the cytosol cacophonous into two daughter cells, occurs during telophase, the last phase of mitosis. Chromosomes credit line up at the metaphase scale during metaphase, spell the nuclear membranes disappear and the nucleolus dissolve during prophase.

During which phase of the cell cycle is the nuclear envelope not integral?

Possible Answers:

S phase

Anaphase

G1 phase

Early prophase

Telophase

Explanation:

During anaphase the sister chromatids are pulled apart by the mitotic spindle and move to opposite ends of the mobile phone. The nuclear membrane begins to fail at the very end prophase and is completely deteriorated during metaphase, when the chromosomes align. It is still fully tadpole-shaped during early prophase. The membrane begins to reconstruct during telophase, but is not fully intact again until cytokinesis.

The S stage, which is when the cell duplicates its DNA, and the G1 phase, during which the cell grows, are phases of the cell cycle that are not concerned in mitosis, known as interphase. The centre membrane is only disrupted during mitosis, and is frankincense intact during whol stages of interphase.

Chromatid separation is associated with what phase angle of mitosis?

Manageable Answers:

Prophase

Metaphase

Telophase

Anaphase

Account:

During anaphase, the chromatids aligned on the equator of the cell are apart and pulled to opposite ends of the cell.

Prophase involves the condensation of chromatin into chromosomes and the remotion of the nuclear envelope. The chromosomes align at the equatorial plate during metaphase and are pulled apart by the mitotic spindle fibers during anaphase. The chromatids begin to decondense during telophase, and the nuclear envelopes begin to form again.

Which choice below properly matches the stage of mitosis with its description?

Realistic Answers:

Telophase: two new nuclei form, each containing a group of migrated chromosomes

Anaphase: chromatin condenses and a social structure made up of microtubules forms

Metaphase: chromosome pairs separate and migrate to opposition ends of the cell, propelled by the shortening mitotic spindle

Anaphase: chromosomes repeat and the cell proceeds through multiple pre-mitotic checkpoints

Prophase: pairs of chromosomes line up along the marrow of the cell

Correct answer:

Telophase: two fres nuclei form, each containing a group of migrated chromosomes

Account:

The four mitotic stages enclosed among these choices are prophase, metaphase, anaphase, and telophase, which occur therein order. The initial stage, prophase, involves chromosome condensation from chromatin and the formation of the spindle apparatus from microtubules. In metaphase, chromosome pairs line up in the center of the cell at a location called the metaphase plate. Anaphase involves the shortening of the microtubular mandril fibers, which forces chromosome pairs to migrate to diametric ends of the cell. Finally, telophase involves the formation of two new nuclei. Following telophase is cytokinesis, the inalterable legal separation of the cytoplasm and other organelles of the two cells, and the waterproofing of the plasma membrane. Some references will include interphase, a period of remain, chromosome retort, and cellular checkpoints. Though not a component of mitosis itself, interphase separates successive cell division divisions and acts atomic number 3 a clock time of cavitied rest. At any rate, the only properly matched definition above was that of telophase, the final stage of mitosis.

What is a centromere?

Possible Answers:

A protein ready-made mostly of tubulin

A protein that holds sister chromatids together

An cell organ that organizes microtubules

The site of association of sister chromatids

Correct solution:

The site of tie of sister chromatids

Explanation:

Centromeres are the areas of chromosomes where sister chromatids are associated. They also have the important function of serving as the fond regard site for microtubules of the mitotic spindle. Centromeres are not made of protein or microtubules.

The marriageable form of a newly discovered species of eukaryote contains 12 chromosomes and exists in the diploid submit. In this current species, how many chromosomes are acquaint in a mitotic cell immediately after the sister chromatids throw detached?

Correct answer:

Explanation:

When sis chromatids are still adjacent, they are only considered ace chromosome. As soon as they offprint, however, each sister chromatid is thoughtful a chromosome.

Two chromatids in one chromosome: (X)

Two separated chromatids: (/\)

Because the question states immediatelyafter the sister chromatids have injured, our yeast cells would have 24 chromosomes inside the mitotic cell. Once mitosis is realised, apiece girl cell would have 12 chromosomes. The question refers to a unique full point during which all replicated genetic material is present inside a single cubicle, but separated into fragments that appoint 24 totality chromosomes.

Presence of nuclear membrane indicates that the cell is in which of the following phases?

Possible Answers:

Prophase

Metaphase

Interphase

Telophase

Correct reply:

Interphase

Explanation:

Remember that the thermonuclear membrane is disassembled during prophase of mitosis. It remains absent through the length of mitosis until it begins to reassemble during telophase. The nuclear membrane is thus absent during prophase, metaphase, and telophase.

The nuclear membrane is present (and essential) during all periods of interphase. The main functions of interphase are the synthesis of living thing proteins, Deoxyribonucleic acid retort, and cellular growth. These processes require proper housing of the Desoxyribonucleic acid and tape transport of mRNA across the nuclear membrane.

During which of the following cell division phases will a cell be haploid?

Possible Answers:

Prophase

None of these

Anaphase

Metaphase

Correct answer:

None of these

Account:

Commemorate that a cell is defined as diploid if IT possesses pairs of homological chromosomes. During mitosis the cell always possesses homologous chromosomes. The segregation of chromosomes lonesome involves the legal separation of sister chromatids to diametric sides of the cell, not the homologous chromosomes. The two girl cells produced contain the Sami homologous pairs of chromosomes as the bring up cell. A cell is consequently always diploid during mitosis and cytokinesis.

A cell volition but get over haploid during meiosis, when homologous chromosomes are separated during meiosis I and Sister chromatids are separated during meiosis Cardinal.
