But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of DNA, the chemical that encodes instructions for building and replicating almost all ...

Watson and Crick's discovery of DNA structure in 1953 revealed a possible mechanism for DNA replication. So why didn't Meselson and Stahl finally explain this mechanism until 1958 ...

DNA achieves this feat of storing, coding and transferring biological information though its unique structure. Replication of DNA DNA replication is the process by which a cell makes an identical ...

A team of researchers has used advanced DNA sequencing to develop the most comprehensive atlas yet of genetic change through ...

We employ fully reconstituted yeast and human DNA replication systems to investigate the structure and biochemical mechanism of the eukaryotic replication machinery. A particular focus of the lab is ...

to show that RAD52 proteins form an unexpected spool-like structure composed of two rings of RAD52, each containing 11 copies of protein, that engages all three arms of the "DNA replication fork ...

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 ...

A research team led by Prof. GAN Haiyun from the Shenzhen Institutes of Advanced Technology (SIAT) of the Chinese Academy of Sciences has uncovered a reciprocal regulatory relationship between ecDNA ...
