Human Idiogram - Chromosome 21

Idiogram (karyogram) - A drawing or photograph of the chromosomes of a particular cell.

Chromosome 21

  • the smallest human chromosome
  • about 47 million base pair
  • about 1.5 % of the total DNA in cells
  • contains between 300 and 400 genes (of human estimated 20,000 to 25,000 total genes)


Human Chromosomes: 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | X | Y  
Idiogram Chromosome Banding - The term refers to the light and dark pattern, seen after staining with a dye, of individual chromosomes identified in metaphase. It is only in meiosis and mitosis during metaphase that chromosomes can be easily identified, during the normal cell life (interphase) the chromosomes are unravelled and distributed within the nucleus in chromosome territories. A band is that part of a chromosome which is clearly distinguishable from nearby regions by appearing darker or brighter with one or more banding techniques.
