What else can I help you with?
How many chromosomes are in metaphase?
Metaphase I or Metaphase II? In metaphase I it would have 24. In metaphase II it would have 6.
What stage of mitosis is when sister chromatids separate into individual chromosomes?
Anaphase is the stage of mitosis when sister chromatids separate into individual chromosomes. During this stage, the sister chromatids are pulled apart towards opposite poles of the cell by the spindle fibers.
What do you call the imaginary line that chromosomes line up at during meta phase?
The imaginary line that chromosomes line up at during metaphase of cell division is called the metaphase plate. This is where the sister chromatids align before being separated during anaphase.
If the chromosomes number for a chimp is 48 how many dyads will it have in a somatic cell in metaphase?
A chimpanzee with 48 chromosomes will have 24 dyads in a somatic cell during metaphase. In metaphase, each chromosome consists of two sister chromatids, which are referred to as dyads.
Where does the sister chromatids line up on the equator of the cell?
Sister chromatids line up at the equatorial plane of the cell during metaphase of mitosis. This alignment occurs at what is known as the metaphase plate, where spindle fibers attach to the centromeres of the chromatids. This precise arrangement ensures that each daughter cell receives an identical set of chromosomes during cell division.
During which phase of mitosis do the sister chromatids line up in the center 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.
How many chromosomes are in metaphase?
Metaphase I or Metaphase II? In metaphase I it would have 24. In metaphase II it would have 6.
When during mitosis are sister chromatids visible?
Sister chromatids are visible during metaphase of mitosis, where they align along the metaphase plate in the center of the cell. This is when the chromosomes are most condensed and easily visible under a microscope.
What stage of mitosis is when sister chromatids separate into individual chromosomes?
Anaphase is the stage of mitosis when sister chromatids separate into individual chromosomes. During this stage, the sister chromatids are pulled apart towards opposite poles of the cell by the spindle fibers.
What do you call the imaginary line that chromosomes line up at during meta phase?
The imaginary line that chromosomes line up at during metaphase of cell division is called the metaphase plate. This is where the sister chromatids align before being separated during anaphase.
Which event occurs during metaphase?
During metaphase, the chromosomes align at the metaphase plate in the center of the cell. The spindle fibers attach to the centromeres of the sister chromatids, preparing to separate them during anaphase. Metaphase is a critical step in mitosis in ensuring accurate chromosome segregation.
If the chromosomes number for a chimp is 48 how many dyads will it have in a somatic cell in metaphase?
A chimpanzee with 48 chromosomes will have 24 dyads in a somatic cell during metaphase. In metaphase, each chromosome consists of two sister chromatids, which are referred to as dyads.
Description of metaphase?
the chromosomes will move in the equatorial plane
What is the difference between sister and non sister chromatids?
Sister chromatids are those replicated from the same chromosome whereas non-sister chromatids may be found in meiosis (particularly metaphase II) where paternal and maternal chromatids line up and eventually separate at the metaphase plate.
What happens in metaphase 2?
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.
What phase of mitosis do sister chromatids line up in the center of the cell?
This phase is called the metaphase. Remember' M' for middle and 'M' for metaphase. In the next phase (anaphase) the chromosomes move away from each other: remember 'A' for away. Telophase is the last or 'terminal' phase: remember 'T' for terminal. Prophase occurs prior to (ie before) the other phases: remember 'P' for prior. Interphase is in between cells divisions: remember 'I' for in between. Clear answer is metaphase.
Homologous chromosomes pair and undergo crossing over during?
prophase I of meiosis. This process involves the exchange of genetic material between non-sister chromatids, resulting in genetic variation among gametes.
