Acid Quote by Francis Crick
“How is the base sequence, divided into codons? There is nothing in the backbone of the nucleic acid, which is perfectly regular, to show us how to group the bases into codons.”
About This Quote
Source Scientific Lecture: Molecular Biology, 1961
Codons are read in groups of three nucleotides, a pattern inferred from protein synthesis despite no explicit markers.
In simple terms: DNA is read in three‑letter units called codons.
Key Takeaway
Recognize three‑base groupings in genetic sequences.
