In this diagram of a duplicated chromosome, (2) identifies the centromere—the region that joins the two sister chromatids, or each half of the chromosome. In prophase of mitosis, specialized regions on centromeres called kinetochores attach chromosomes to spindle fibers. The centromere links a pair of sister chromatids together during cell ...

A bracket is used to connect two or more lines of music that sound simultaneously. In contemporary usage it usually connects staves of individual instruments (e.g., flute and clarinet ; two trumpets ; etc.) or multiple vocal parts, whereas the brace connects multiple parts for a single instrument (e.g., the right-hand and left-hand staves of a ...
A chromatid (Greek khrōmat- 'color' + -id) is one half of a duplicated chromosome. Before replication, one chromosome is composed of one DNA molecule. In replication, the DNA molecule is copied, and the two molecules are known as chromatids. [1] During the later stages of cell division these chromatids separate longitudinally to become ...
A kinetochore (/ kɪˈnɛtəkɔːr /, /- ˈniːtəkɔːr /) is a disc-shaped protein structure associated with duplicated chromatids in eukaryotic cells where the spindle fibers attach during cell division to pull sister chromatids apart. [ 1 ] The kinetochore assembles on the centromere and links the chromosome to microtubule polymers from the ...
The centrosome is copied only once per cell cycle, so that each daughter cell inherits one centrosome, containing two structures called centrioles. The centrosome replicates during the S phase of the cell cycle. During the prophase in the process of cell division called mitosis, the centrosomes migrate to opposite poles of the cell. The mitotic ...
