In the diagram, (1) refers to a chromatid: 1-half of two identical threadlike strands of a replicated chromosome.During cell division, the identical copies (called a "sister chromatid pair") are joined at the region called the centromere (2).
Diagram of a duplicated and condensed eukaryotic chromosome. (1) Chromatid – one of the two identical parts of the chromosome after S phase. (2) Centromere – the point where the two chromatids touch, and where the microtubules attach. (3) Short arm (p). (4) Long arm (q).
A sister chromatid refers to the identical copies formed by the DNA replication of a chromosome, with both copies joined together by a common centromere. In other words, a sister chromatid may also be said to be 'one-half' of the duplicated chromosome. A pair of sister chromatids is called a dyad.
Each chromatid has its own kinetochore, which face in opposite directions and attach to opposite poles of the mitotic spindle apparatus. Following the transition from metaphase to anaphase , the sister chromatids separate from each other, and the individual kinetochores on each chromatid drive their movement to the spindle poles that will ...
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.
(1) Chromatid. One of the two identical parts of the chromosome after S phase. (2) Centromere. The point where the two chromatids touch, and where the microtubules attach. (3) Short (p) arm (4) Long (q) arm. In accordance with the display rules in Cytogenetics, the short arm is on top.
From ancient history to the modern day, the clitoris has been discredited, dismissed and deleted -- and women's pleasure has often been left out of the conversation entirely. Now, an underground art movement led by artist Sophia Wallace is emerging across the globe to challenge the lies, question the myths and rewrite the rules around sex and the female body.
