http://cyberbridge.mcb.harvard.edu/mitosis_5.html 網頁A karyotype shows the chromosomes in an individual. Humans have 23 paired chromosomes, meaning there are two copies of each chromosome. In the karyotype, chromosome 21 is shown to have 3 copies rather than 2 copies. So, the 3 copies of chromosome 21 is the abnormality in this karyotype.

網頁2024年5月17日 · During the ensuing interphase (the period between two cell divisions), the chromosomes decondense, the genome can be duplicated and the genes expressed. However, a single human cell contains up to two meters of DNA: is the nuclear envelope on its own sufficient to contain the genome inside the nucleus during interphase? 網頁The chromatin begins to decondense and the nucleoli reappear. During telophase, all the nuclear proteins, including RanGTP ( Pay et al., 2002 ), must be rounded up and brought back to the nucleus (see Chapter 16 ).
