chromosomernas
Chromosomes are thread-like structures found inside the nucleus of eukaryotic cells. They are composed of DNA tightly coiled around proteins called histones. This DNA contains the genetic instructions for the development, functioning, growth, and reproduction of all known living organisms and many viruses. The term "chromosome" comes from the Greek words for "color" and "body," referring to their ability to be stained by dyes.
Humans typically have 23 pairs of chromosomes in each somatic cell, totaling 46. Twenty-two of these pairs
The organization of DNA into chromosomes allows for efficient packaging of a large amount of genetic material
