The hydrogen bonds between the base pairs, along with the stacking interactions between adjacent base pairs, help maintain the helical structure of DNA. The width of the double helix is uniform, with ...

These physical spacers are known as L2 loops, and each insertion exposes the bases of three DNA nucleotides that are then available for the invading strand to pair to, probing for homology.

Chemical Structure and Properties. Thymine is a heterocyclic aromatic organic compound with the chemical formula C 5 H 6 N 2 O 2. Its systematic name is 5-methyluracil, ... In the double helix ...

This DNA is distinguished by a base, found nowhere else, that undergoes a different type of base pairing. Diaminopurine, awkwardly abbreviated as Z, is structurally similar to the adenine (A ...

Complementary Base-Pairing. The two DNA strands in the double helix run in opposite directions (antiparallel to each other) to help the bases in each base pair fit into the double helix.

DNA is the molecular basis of heredity, the inherited traits that pass between generations in a person's family tree. Embodied in the sequence of base pairs, DNA carries information between ...

"We have obtained a cryo-electron microscopy structure that captures the state of human Rad51 tightly bound to broken DNA," says co-lead author Luay Joudeh, Microscopy Manager at the Departments ...
