“chromosomes”
1. Any of the threadlike structures in the nucleus of a cell that function in the transmission of genetic information.
2. Etymology: from German Chromosom, coined in 1888 by the German anatomist, Wilhelm von Waldeyer-Hartz (1836-1921), from Greek khroma, "color" + soma, "body". This term was coined because the structures contain a substance that stains readily with basic dyes.
Each chromosome consists of a double strand of DNA attached to proteins called histones.
The genes, which contain the genetic material that controls the inheritance of traits, are arranged in a linear pattern along the length of each DNA strand.
Each species has a characteristic number of chromosomes in each somatic cell. In humans, there are forty-six chromosomes, including twenty-two homologous pairs of autosomes and one pair of sex chromosomes.
One member of each pair is derived from each parent.
