The DNA molecule is shaped like a twisted ladder.
15251. Discovering the rules of complementary base pairing, Erwin Chargaff
Erwin Chargaff talks about his discovery â a major step for building the DNA model.
15495. Chargaff's ratios, 3D animation with narration
Erwin Chargaff found that in DNA, the ratios of adenine (A) to thymine (T) and guanine (G) to cytosine (C) are equal. This parity is obvious in the final DNA structure.
15250. Complementary base pairing, Erwin Chargaff
Erwin Chargaff talks about his name for Chargaff's ratios.
15252. First impression of Watson and Crick, Erwin Chargaff
Erwin Chargaff reads a passage from his book Heraclitean Fire: Sketches from a Life Before Nature, describing his impressions of Crick and Watson.
16422. Animation 19: The DNA molecule is shaped like a twisted ladder.
James Watson and Francis Crick explain how they solved the structure of DNA. Erwin Chargaff explain how he measured the levels of each of the four nitrogenous bases.

The work of Erwin Chargaff and how it contributed to the downfall of Levene's tetranucleotide theory.
15682. DNA nucleotides
DNA nucleotides (black letter tiles) matched in groups of two to amino acids (red letter tiles).
15617. DNA nucleotide mutation
A single DNA nucleotide undergoes a "point" mutation, changing an A to a T.
