Answer: 10
If there are 20 chromatids in a cell how many centromeres are there?

In rare cases neocentromeres can form at new sites on a chromosome as a result of a repositioning of the centromere. This phenomenon is most well known from human clinical studies and there are currently over 90 known human neocentromeres identified on 20 different chromosomes. The formation of a neocentromere must be coupled with the inactivation of the previous centromere since chromosomes with two functional centromeres (Dicentric chromosome) will result in chromosome breakage during mit…

In cell biology mitosis (/ m aɪ ˈ t oʊ s ɪ s /) is a part of the cell cycle in which replicated chromosomes are separated into two new nuclei. Cell division gives rise to genetically identical cells in which the total number of chromosomes is maintained. In general mitosis (division of the nucleus) is preceded by the S stage of interphase (during which the DNA is replicated) and is often …
