chromatid

chromatid A threadlike strand formed from a chromosome during the early stages of cell division. Each chromosome divides along its length into two chromatids, which are at first held together at the centromere. They separate completely at a later stage. The DNA of the chromosome reproduces itself exactly so that each chromatid has the complete amount of DNA and becomes a daughter chromosome with exactly the same genes as the original chromosome from which it was formed.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.

chromatid

chromatid One of the two daughter strands of a chromosome that has undergone division. Chromatids are joined together by a single centromere, usually positioned in the centre of the pair as they lie beside one another. When the centromere divides during the third stage (anaphase) of cell division (mitosis or meiosis), the sister chromatids become separate chromosomes.

chromatid

chromatid One of the two daughter strands of a chromosome that has undergone division. Chromatids are joined together by a single centromere, usually positioned in the centre of the pair as they lie beside one another. When the centromere divides at the anaphase of mitosis or the second stage of meiosis (meiosis II), the sister chromatids become separate chromosomes.
