Nettet15333. Linus Pauling' s manuscript describing incorrect triple helix, Peter Pauling. In 1952, Peter Pauling was a student at Cambridge when his father, Linus, sent him a paper proposing that DNA was a triple helix. James (Jim) Watson eagerly read the paper and realized that Pauling got it wrong. ID: 15333. Source: DNAi. Nettet18. aug. 2024 · The building blocks of DNA are nucleotides, which are made up of three parts: a deoxyribose (5-carbon sugar), a phosphate group, and a nitrogenous base (Figure 5.1.1. 2 ). There are four types of nitrogenous bases in DNA. Adenine (A) and guanine (G) are double-ringed purines, and cytosine (C) and thymine (T) are smaller, single-ringed …
