WebNov 26, 2024 · A DNA molecule is a double helix with two polynucleotide chains held together by hydrogen bonds between specific complementary base pairs. An RNA molecule is a relatively short polynucleotide chain. Students should be able to appreciate that the relative simplicity of DNA led many scientists to doubt that it carried the genetic code. Webthymine pairs with adenine (T-A) guanine pairs with cytosine (G-C) These basic units are linked together to form strands by strong bonds between the deoxyribose sugar of one …

At the end of the sequence, when the acetal has been formed, the nucleophilic alcohol has been transformed into an ether, but the nucleophilic center, the "alcoholic" oxygen, remains intact. WebSo this is the most stable conjugate base out of these three. Therefore, this is the most acidic compound out of these three. The inductive effect falls off over distance. So if we look at this acid here, this is called butanoic acid. So this is carbon one, this is carbon two, this is carbon three, and this is carbon four.
