How is antaphase 2 in meiosis similar to anaphase in mitosis?
The centrioles move apart to opposite ends of the cell, the chromosomes become attached to the fiber connected to centrioles pulling the chromatids apart; when this is over all the chromatids line up.
Do chromatids separate during telophase?
chromatids separate during anaphase.anaphase is when the spindle fibers start pulling the "sister" chromatids apart
Why do chromosomes coil during mitosis?
The chromosomes line up so that the sister chromatids can get separated by the pulling action of spindle fibres. These sister chromatids are then divided into the two cells - one cell gets each. The lining up is important so that there is equal division.
How does DNA contribute to Mitosis?
During mitosis, DNA in the nucleus is copied and passed to the new cells Cell Division occurs in a series of stages, or phases. 1st Interphase: - Chromosomes are copied (#doubles) - Chromosomes appear as threadlike coils (chromatin) at the start, but each chromosome and its copy (sister chromosome) change to sister chromatids at end of this phase. 2nd Prophase: - Mitosis begins (cells begin to divide) - Centrioles (or poles) appear to begin to move to opposite ends of the cell. - Spindle fibers form between the poles. 3rd Metaphase: - Chromatids (or pairs of chromosomes) attach to the spindle fibers. 4th Anaphase: - Chromatids (or pairs of chromosomes) seperate and begin to move to opposite ends of the cell. 5th Telophase: - Two new nuclei form. - Chromosomes appear as chromatin (threads rather than rods) - Mitosis ends. 6th Cytokinesis: - Cell membrane moves inward to create two daughter cells -- each with its own nucleus with identical chromosomes.
What is the function of mircotubules during anaphase?
During anaphase, the chromatids separate and move towards the spindle poles by the shortening of the kinetochore microtubules.
What stage do the sister chromatids move to oposite ends of the cell?
SIster chromatids move to opposite poles of the cell when the spindle fibres contract, pulling them apart. This occurs during the stage in mitosis known as anaphase.

What phase of mitosis has cells pulling apart?
metaphase
Do chromatids separate during telophase?
chromatids separate during anaphase.anaphase is when the spindle fibers start pulling the "sister" chromatids apart
How might spindle microtubules assist in the process of splitting centromeres?
creating tension by pulling toward opposite poles
What is involved in cell devision in animal cells?
Well the actual process of Mitosis is involved with cell division. Interphase: DNA is replicated. Early Prophase: Nuclear membrane disintegrates. Late Prophase: Chromosomes appear in as double-chromatids. Spindles form. Metaphase: The spindles organise the chromosomes on the equator of the cell. Anaphase: Chromosomes segregate, pulling the chromatids apart. Late Anaphase: Single chromatids are drawn to the centrosomes. Telophase: Two nuclei form. The cell plate forms across the midline of the parent cell. Cytokinesis: Division of cytoplasm is complete. The two daughter cells are separate.
What is the middle of the mitotic spindle?
In the middle of mitotic spindle are the duplicated chromosomes held by kinetochores. These are protein structures are involved in pulling apart the sister chromatids.
How do you behave freely?
usually it involves pulling down your pants in public and crying.
What phase of the eukaryotic cell cycle do microtubules arrange in preparation for mitosis?
they are produced by centrosome and they bind to the centromeres of sister chromatids during metaphase pulling each sister chromatid opposite sides so each daughter cell would contain one of them. mitotic division doesnt proceeds before microtubules bind to each centromere
Why do chromosomes coil during mitosis?
The chromosomes line up so that the sister chromatids can get separated by the pulling action of spindle fibres. These sister chromatids are then divided into the two cells - one cell gets each. The lining up is important so that there is equal division.
What do two things do when there is a pair of forces pulling them together?
they do this thing that involves custard and bananas
What is the application of pulling force to hold a bone in correct alignment?
Traction involves applying a pulling force on a fracture in order to restore normal alignment.
