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 ...

Stylized DNA replication fork with nucleotides matched, 5'->3' synthesis shown, no enzymes in diagram. Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news releases posted ...

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 ...

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 ...

When a cell divides to give rise to two daughter cells, the DNA-replicating machinery unfolds the chromatin as it moves along the DNA strands. Once the so-called replication fork (the structure ...

The replication fork continues for a total of two-thirds of the genome before encountering the O L. This results in the single-stranded DNA in this region to form a stem-loop structure which ...

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 ...
