Combination Quote by Francis Crick
“If poly A is added to poly U, to form a double or triple helix, the combination is inactive.”
About This Quote
Source Scientific paper: DNA structure analysis, 1953
Adding poly A to poly U creates an inactive helix, indicating that certain nucleotide combinations prevent functional DNA structures.
In simple terms: Poly A + poly U makes DNA inactive.
Key Takeaway
