the 'wings' and N-termini of RTP do not form intimate contacts with the DNA. This structure provides insight into the molecular basis of polar replication fork arrest based on a model of ...

Given its importance, DNA replication is tightly regulated, primarily upon initiation at genomic sites known as origins of replication. A two-pronged structure known as a replication fork forms at ...

Revising DNA structure and replication? This Higher Human Biology guide is packed with information to help. Higher Human Biology - Structure and replication of DNA. revision-guideHigher Human ...

Double ring structure protects DNA Spies and Pichierri had previously discovered that RAD52 is important in protecting stalled DNA replication forks. Their work suggested that this new function of ...

However, the process of DNA replication intrinsically disrupts nucleosomes ahead of the fork raising the question how chromatin structure is maintained across generations. Nucleosomes are re-assembled ...

An enzyme called a helicase unwinds the double helix structure ... Sophie L Williams et al, Replication‐induced DNA secondary structures drive fork uncoupling and breakage, The EMBO Journal ...

Each time a part of a chromosome unwinds for replication, regions of DNA unzip, forming a structure that looks like a fork in the road. For replication to proceed, the fork must move down the ...
