The hydrogen bonds in DNA Watson–Crick base pairs have long been considered predominantly electrostatic phenomena. In this chapter, we show with state-of-the-art calculations that this is not true and that electrostatic interactions and covalent contributions in these hydrogen bonds are in fact of...
How are nucleotides added in DNA replication? How is DNA polymerase made? How is transcription driven by phosphodiester bonds? What method was used to discover the structure of DNA? What kind of chemical bond is found between paired bases of the DNA double helix?

Parsing the genomic sequence of cyanophage S-2L (AX955019) in the search for a protein involved in DNA replication, we identified one ORF corresponding to a member of the Archaeo-Eukaryotic Primase (AEP) superfamily, which had not been noted earlier. We will refer to it as “PrimPol”, ...

An example of intramolecular hydrogen bonding is aDNAmolecule, where the nitrogen bases from the two strands are joined by intramolecular hydrogen bonds (seeFig. 2.5). The hydrogen bonding between nitrogen bases is critical toDNA structureand is important to DNA translation and replication. ...
Why Alpha Helix Hydrogen Bonds? Alpha helices make more efficient use of hydrogen bonding availability compared to beta pleated sheets and thus are more compressed. Alpha helices are also the most common secondary structure in proteins.Alpha Helix Structure Alpha Helix Proteins Lesson Summary Register ...
Answer to: What enzyme catalyzes the breaking of the hydrogen bonds between the base pairs of the two DNA strands to separate them for replication?...
Hydrogen bonding has been traditionally accepted as the underlying force in the formation of base pairs: adenine-thymine (A:T) and guanine-cytosine (G⋮C), generally referred to as Watson–Crick type of base pairing, requiring two or three hydrogen bonds, respectively. The AT and GC base ...
