|DNA.....Your genetic code|
Watson and Crick determined that DNA is a double helix. In other words, it looks like a twisted ladder. The sides of the ladder are made of alternating sugar and phosphate molecules. The special sugar used in DNA is deoxyribose.
Phosphate Deoxyribose Phosphate Deoxyribose Phosphate
The rungs of the ladders are made of pairs of molecules called bases.
Trivia....If you stretched out all the DNA from one person, it would go from Earth to Pluto and back 20 times!
