Chromosome classification

By R. A. / 12/02/2016 / RSIP Vision Learns / No Comments

Chromosomes are packaged and organized structures which contain most of the DNA of living organisms. The DNA that constitutes the chromosomes becomes more tightly aligned in the middle of the cell during the metaphase (the cell division) and is then visible on a microscope. In humans, each cell g...
