Metaphase I or Metaphase II? In metaphase I it would have 24. In metaphase II it would have 6.
metaphase.
A human body cell has 46 chromosomes. Before mitosis, the DNA/chromosomes replicate, resulting in 92 chromosomes which will be divided into two genetically identical daughter cells during mitosis.
The chromosome pairs are lined up in the center of the cell, parts of the cytoskeleton have formed the mitotic spindle and are preparing to pull the pairs apart.
In Metaphase the chromatids line up at the equator/midplane of the cell.
Chromosomes are composed of two chromatids during the prophase and metaphase of mitosis. The chromosomes of formed in prophase and line up in metaphase.
Metaphase I or Metaphase II? In metaphase I it would have 24. In metaphase II it would have 6.
during the metaphase. and they are called sister chromatids, not double chromosomes
metaphase.
A human body cell has 46 chromosomes. Before mitosis, the DNA/chromosomes replicate, resulting in 92 chromosomes which will be divided into two genetically identical daughter cells during mitosis.
the chromosomes will move in the equatorial plane
Yes. Sister chromatids separate and become individual chromosomes during anaphase.
During metaphase of meiosis 2, or metaphase II, there are 3 major points. 1st is the chromosomes are positioned on the metaphase plate as in mitosis. 2nd is, because of the crossing over in meiosis I, the two sister chromatids of each chromosome are not genetically identical. 3rd is the kinetochores of sister chromatids are attached to microtubules extending from opposite poles.
The sister chromatids first appear in the S phase of the cell cycle.
The chromosome pairs are lined up in the center of the cell, parts of the cytoskeleton have formed the mitotic spindle and are preparing to pull the pairs apart.
They pull the sister chromatids apart.
During metaphase they line up along the cell's equatorial plane as pairs of sister chromatids, and during anaphase the sister chromatids separate (now called chromosomes) and are pulled to opposite poles of the cell.
