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 ...
University of Iowa-led study has revealed the unexpected structure adopted by the DNA repair protein RAD52 as it binds and protects replicating DNA in dividing cells. A University of Iowa-led study ...
Structural biologists at the University of Wisconsin-Madison today published cryo-electron microscopy structures of the complete bacterial DNA replication restart complex — a molecular machine that le ...
Researchers at The University of Texas MD Anderson Cancer Center have developed a new imaging method, known as RF-SIRF, that quantitatively detects and maps reversed DNA replication forks with ...
In turn, this slowed new DNA synthesis at replication forks, structures in which double strands of DNA separate to begin the copying process. The cells' attempt to restart the stalled replication fork ...
Embryonic stem (ES) cells are pluripotent stem cells that can produce all cell types of an organism. ES cells proliferate rapidly and have been thought to experience high levels of intrinsic ...
Replication origins in Trypanosoma brucei integrate multiple features previously described individually in opisthokonts, revealing a unified structural topology built from strand-specific nucleotide ...
A University of Iowa-led study has revealed the unexpected structure adopted by the DNA repair protein RAD52 as it binds and protects replicating DNA in dividing cells. This new structural and ...
Despite the importance of DNA replication, numerous aspects of this process are still poorly understood. One fundamental question is: how do replication forks efficiently progress through chromatin?
