Similarly, DNA molecules, shaped like twisted rope ladders, carry encoded information that underpins all life and that makes living things differ ​ — bananas from beans, zebras from ants, humans from whales.
Oma kujult köisredelit meenutavad DNA molekulid kannavad samuti endas kogu elutegevuse alusmüürina toimivat kodeeritud infot. See info eristabki kõike elavat: banaane ubadest, sebrasid sipelgatest, inimesi vaaladest.
