Who gave the name DNA?
KEY FACTAlbrecht Kossel isolated the five nucleotide bases that are the building blocks of DNA and RNA: adenine, cytosine, guanine, thymine and uracil. In 1881 Albrecht identified nuclein as a nucleic acid and provided its present chemical name, deoxyribonucleic acid (DNA).
Is your DNA 50/50 from your parents?
The particular mix of DNA you inherit is unique to you. You receive 50% of your DNA from each of your parents, who received 50% of theirs from each of their parents, and so on. If you go back far enough, there is a chance that you inherited no DNA from a particular ancestor.
Are breastfed babies smarter?
