DNA: Types, Structure and Function of DNA
DNA is called a nucleic acid because it was first found in the nucleus. We now know that DNA is also found in other organelles, the mitochondria and chloroplasts, though it is the DNA in the nucleus that actually controls the cell's workings. In 1953, James Watson and Francis Crick established the structure of DNA.
