Concepts of chromatin-chromosome-chromatids
How are concepts of chromatin, chromosome and chromatids associated? In which phase of cell cycle does DNA replicate?
Expert
Chromatin is a position of filamentous DNA molecules which is dispersed in karyoplasm forming euchromatin as well as in heterochromatin. Each and every chromatin filament is a complete chromosome (or a DNA molecule, double helix). The chromatin of human somatic cell is formed through the forty six DNA molecules (or twenty two homologous chromosomes and one pair of the sex chromosomes).
In the interphase the cell generates itself for division and replication of the DNA molecules takes place. The replication of every DNA molecule finds two indistinguishable DNA double helix bound by a structure which is named as centromere. In this segment each and every identical chromosome of these pairs are named as chromatid. It is as well during the interphase that the chromatids start to condensate supposing the shorter and thicker shape typical of chromosome illustrations. So the phase of cell cycle in that DNA replicates is the interphase.
In the short run the supply curve for a firm is the short-run marginal cost curve (above the point of minimum average variable cost). Why is the supply curve in the long run not in the long-run marginal cost curve (above the point of minimum average net cost)
