WebDNA is short for deoxyribose nucleic acid The structure of DNA is a double helix. words, it is a double stranded molecule that twists like a spiral staircase. The outsides of the molecule, the railings of the staircase, are made of deoxyribose sugars alternating with phosphates. This part of the molecule is sometimes called the Weba. The DNA double helix is composed of two strands of DNA; each strand is a polymer of DNA nucleotides. Each nucleotide consists of a sugar, a phosphate group, and one of four nitrogenous bases. The structure and orientation of the two strands are important to understanding DNA replication.

WebFeb 21, 2024 · Here, we report cryo-EM structures of polα-primase in complex with primed templates representing various stages of DNA synthesis. Our data show how interaction of the primase regulatory subunit with the primer 5'-end facilitates handoff of the primer to polα and increases polα processivity, thereby regulating both RNA and DNA composition.
