When DNA breaks, cells must repair it accurately to prevent harmful mutations. Researchers have discovered that during a key ...

The statement that "Mutations can occur spontaneously" is also true. Spontaneous mutations arise naturally due to inherent ...

A new fluorescent sensor is giving scientists an unprecedented view of how cells respond to DNA damage, capturing the repair process as it unfolds in real time. The tool, developed at Utrecht ...

Cancer research, drug safety testing and aging biology may all gain a major boost from a new fluorescent sensor developed at Utrecht University. This new tool allows scientists to watch DNA damage and ...

The bowhead whale’s remarkable lifespan and low cancer risk stem from a finely tuned DNA repair system driven by a unique protein, CIRBP. Scientists found that this mechanism not only preserves the ...

"DNA sensor cyclic guanosine monophosphate–adenosine monophosphate synthase (cGAS) participates in regulating DNA double-strand break repair by suppressing the homologous recombination (HR) pathway, ...

Naked mole-rats are well known for both their wrinkly appearance and for their unexpectedly long lives. The source of this extended lifespan has been under scrutiny for decades. While many rodents are ...

A clump of proteins seems to be in charge of the level of DNA repair that takes place in our bodies, determining how fast mutations accumulate in our cells over a lifetime – and might thus affect our ...

The human genome consists of 3 billion base pairs, and when a cell divides, it takes about seven hours to complete making a copy of its DNA. That's almost 120,000 base pairs per second. At that ...

ABSTRACT: The effect of heat shock on certain meiotic parameters in Drosophila melanogaster was studied in the cv – v – f region of the X chromosome of females homozygous for the mus309 mutation, ...
