Chromosome and Chromatid Numbers during Mitosis and Meiosis. A topic in biology that many students find challenging (and is known to appear on the DAT) is the number of chromosomes and chromatids present during the various stages of meiosis and mitosis in eukaryotes.

So it's more or less straightforward in mitosis: The chromosome number remains constant (46 total chromosomes or 23 pairs of chromosomes). The chromatids replicate during interphase to produce a total of 92 chromatids, but they're only found in pairs and remain connected at the center by the centromere.; After mitosis, the chromatid pairs separate, so each daughter cell gets 46 chromatids.

The number of chromosomes increases only when sister chromatids separated during anaphase of mitosis and anaphase II of meiosis. Think, in anaphase I of meiosis, only homologous chromosomes are separated. Only in anaphase II sister chromatids are separated.

During all three parts of interphase, the cell grows by producing proteins and cytoplasmic organelles. However, chromosomes are replicated only during the S phase. Thus, a cell grows (G 1), continues to grow as it duplicates its chromosomes (S), grows more and prepares for mitosis (G 2), and finally divides (M) before restarting the cycle.

During mitosis, the chromosomes are pulled away by spindle fibers that come from each pair of centrioles at the opposite ends of the cell. The reason this happens is so that each new daughter cell ...

en.wikipedia.org/wiki/Metaphase

Metaphase (from the Greek μετά, "adjacent" and φάσις, "stage") is a stage of mitosis in the eukaryotic cell cycle in which chromosomes are at their second-most condensed and coiled stage (they are at their most condensed in anaphase). These chromosomes, carrying genetic information, align in the equator of the cell before being separated into each of the two daughter cells.

Chromosome and chromatid (DNA) number in humans during different stages of mitosis ... How to count the number of chromosomes and chromatids in meiosis or mitosis? I found this in many past question papers. In order to answer such questions we need to have some basic concepts regarding chromosomes and chromatids.
