DNA, Genes, Chromosomes

The building blocks of inheritance

DNA (deoxyribonucleic acid) is a biomolecule that holds the blueprint for how living organisms are built.  DNA is made out of two long, twisted strands that contain complementary genetic information (like a picture and its negative). A gene is a segment of DNA that is passed down from parents to children and confers a trait to the offspring. Genes are organized and packaged in units called “chromosomes.”  Humans have 23 pairs of chromosomes. One set of chromosomes for each pair comes from a person’s mother, and the other set of chromosomes comes from the father.
