DNA damage tolerance (DDT), activated by replication stress during genome replication, is mediated by translesion synthesis and homologous recombination (HR). Here we uncover that DDK kinase, ...

Genome-wide studies of DNA replication origins revealed that origins preferentially associate with an Origin G-rich Repeated Element (OGRE), potentially forming G-quadruplexes (G4). Here, we ...

From 'Why a double helix?', 'What are 5′ and 3′?', to 'Why can it replicate?'—DNAis a molecule that stores information in the ...

Every time a cell divides, it must copy roughly three billion letters of DNA with near-perfect fidelity. That copying process, DNA replication, is among the most demanding operations a cell performs, ...

OCR A Level Biology A lesson on DNA Replication. This is one of seven lessons to meet the specification points for 2.1.3 Nucleotides and Nucleic Acids. Objectives for this lesson: State why DNA ...

It has been discovered that there are multiple types of DNA sites prone to breakage, beyond those previously known. This was announced by RIKEN, Kobe University, and JST. By examining cells one by one ...

The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by DNA damage. Among the most dangerous lesions are DNA interstrand crosslinks ...

DNA polymerases are enzymes that create DNA molecules by assembling nucleotides, the building blocks of DNA. These enzymes are essential to DNA replication and usually work in pairs to create two ...
