Found Centromere 19 times.

Displaying results 1 to 10.

1. Acentric
This term refers to a chromosome or chromatid that lacks a centromere ; this condition can result during crossing over in which the normal, centromere-containing segment is replaced by an inverted segment that lacks a centromere.

2. Acrocentric
A chromosome or chromatids with a non-centrally-located centromere , producing chromosome arms with unequal lengths.

3. Acrocentric
An acrocentric chromosome has its centromere closer to one end than to the other, resulting in unequal chromosome arms.

4. Anaphase
The stage in mitosis following metaphase . The paired chromatid s are separated from each other and moved to opposite ends of the cell . The stage begins as soon as the centromere s connecting each chromatid to its pair break and ends when the two new sets of chromosome s arrive at opposite ends of the cell.

5. Anaphase II
The stage in the second meiotic division of meiosis that follows metaphase II . In each cell produced during the first meiotic division , the paired chromatid s are separated from each other and moved to opposite ends of the cell. The stage begins as soon as the centromere s connecting each chromatid to its pair break and ends when the two new sets of chromosome s arrive at opposite ends of each cell.

6. Aster
A star-shaped structure, composed of microtubule s, which surrounds the centriole s during mitosis in animals. The aster forms during prophase . The spindle fiber s arise gradually between the two asters (at opposite ends of the cell ) until they attach to the kinetochore s of the centromere s of each chromosome. Asters are not found in vascular plant cells.

7. C banding
A lab technique to stain the repeated DNA sequences (called satellite DNA ) which occur near the centromere on a chromosome .

8. Centromere
A specialized chromosome region to which spindle fibers attach during cell division ( mitosis ).

9. Centromere
A specialized region on each chromatid to which kinetochores and sister chromatids attach.

10. Chromatid
One of two daughter chromosome s after duplication but before separation from the other daughter chromosome (they can also be called "sister chromatids"). The pair of chromatids are joined together with a centromere , and can be seen during the earlier stages of mitosis and meiosis before the pair is separated and pulled to opposite ends of the nucleus .
