In the double helix structure of DNA, thymine forms a base pair with adenine through two hydrogen bonds. This specific pairing is known as complementary base pairing and is essential for the stability ...

DNA replication is a complex process with many moving parts. In baker's yeast, the molecular complex Ctf18-RFC keeps parts of the replication machinery from falling off the DNA strand. Human cells use ...

An international collaborative research team has discovered that G-quadraplex DNA (G4-DNA) accumulates in neurons and dynamically controls the activation and repression of genes underlying long-term ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

Humans and baker's yeast have more in common than meets the eye, including an important mechanism that helps ensure DNA is copied correctly, reports a pair of studies. The findings visualize for the ...
