During DNA replication, the unwinding of strands leaves a single strand vulnerable. How does the cell protect these strands from damage? How would you identify the protein that serves as a connector ...
Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...
Unrepaired DNA-protein crosslinks (DPCs) – highly toxic tangles of protein and DNA – cause a process that leads to premature ...
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 ...

DNA, though tightly packed in the nucleus, is constantly threatened by damage from metabolism and external stressors. One particularly severe form of DNA damage is the so-called DNA–protein crosslinks ...
For almost 60 years, scientists have tried to understand why DNA doesn't replicate wildly and uncontrollably every time a ...
DNA is often described as the instruction manual for building the fundamental components of life. Proteins are helpers that aid DNA in carrying out essential processes such as replication, repair, and ...
