Jun 8, 2025 · During this stage, sister chromatids are pulled to opposite ends of the cell. The spindle fibres contract, breaking the chromatids at the centromere and moving them to opposite poles of the …

May 11, 2006 · In anaphase, the paired chromosomes (sister chromatids) separate and begin moving to opposite ends (poles) of the cell. Spindle fibers not connected to chromatids lengthen and elongate …

DNA condenses into chromosomes made up of two sister chromatids connected at the centromere -- spindle fibers form and spread from centrioles -- nuclear envelope break down and the centrioles will …

In metaphase, chromosomes are lined up and each sister chromatid is attached to a spindle fiber. In anaphase, sister chromatids (now called chromosomes) are pulled toward opposite poles.

In particular, the image shows the cell in a part of cell division called anaphase, where the DNA is being pulled to opposite ends of the cell. Normally, DNA is located in the nucleus of most human cells.

Their DNA becomes tightly coiled up and the replicated chromosomes become visible as separate units. The chromosomes shorten and thicken and can now be seen as pairs of chromatids .

Jan 1, 2026 · These separate chromosomes are pulled apart by shortening spindle fibers, and pulled toward the centrosomes to which they are attached. At the end of anaphase the spindle fibers degrade.

The centromere links a pair of sister chromatids together during cell division. This constricted region of chromosome connects the sister chromatids, creating a short arm (p) and a long arm (q) on the …

Oct 11, 2024 · Chromosome Separation: During anaphase, spindle fibers pull sister chromatids apart toward opposite poles of the cell. Ensuring Even Distribution: By organizing the spindle, centrioles …

4 days ago · It is a specific kind of repetitive DNA, called "alpha satellite." The alpha satellite DNA is where the proteins that the centromere needs to attach to the spindle fibers come together. A …
