chromatid

 [kro´mah-tid]
either of two parallel filaments joined at the centromere that make up a chromosome and that divide in cell division, each going to a different pole of the dividing cell and each becoming a chromosome of one of the two daughter cells.

chro·ma·tid

(krō'mă-tid),
Each of the two strands formed by longitudinal duplication of a chromosome that becomes visible during prophase of mitosis or meiosis; the two chromatids are joined by the still undivided centromere; after the centromere has divided at metaphase and the two chromatids have separated, each chromatid becomes a chromosome.
[G. chrōma, color, + -id (2),]

chromatid

/chro·ma·tid/ (kro´mah-tid) either of two parallel, spiral filaments joined at the centromere which make up a chromosome.

chromatid

(krō′mə-tĭd)
n.
Either of the two daughter strands of a replicated chromosome that are joined by a single centromere and separate during cell division to become individual chromosomes.

chromatid

[krō′mətid]
Etymology: Gk, chroma, color
one of the two identical, threadlike filaments of a chromosome. Chromatids are produced by the self-replication of the chromosome during interphase and are held together by a common centromere. During anaphase of mitosis and meiosis II, the chromatids separate to become daughter chromosomes.

chromatid

One of the two duplicated copies of a chromosome produced by replication while still connected at the CENTROMERE before separation at the subsequent cell division. Each chromatid becomes a new chromosome.

chromatid

one of a pair of duplicated CHROMOSOMES produced during the ‘S’ phase of the CELL CYCLE, which are joined together at the CENTROMERE. See Fig. 102 . During nuclear division the centromere splits (in anaphase of mitosis, anaphase 2 of MEIOSIS) to produce two separate chromosomes.

chromatid

either of two parallel filaments joined at the centromere which make up a chromosome, and which divide in cell division, each going to a different pole of the dividing cell and each becoming a chromosome of one of the two daughter cells.

sister chromatid
a chromatid formed by a replicating chromosome during interphase; because they are derived from the one homolog and joined at the center they are exact copies of each other.
