Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by ...
The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

Cancer’s most notorious protein MYC quietly repairs the DNA damage chemo inflicts — block that trick and treatment could hit tumor cells far harder
Chemotherapy drugs like doxorubicin and etoposide work by snapping a cancer cell’s DNA in two. The breaks are supposed to be ...
Retrotransposons are sequences of DNA in animal genomes that can replicate and reinsert themselves back into the genome. Experiments in flies and other model systems reveal that retrotransposons ...
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 ...
A protein best known for driving cancer growth also helps damaged tumor cells survive by repairing their DNA, according to a ...
Like its viral cousins, a somewhat parasitic DNA sequence called a retrotransposon has been found borrowing the cell's own machinery to achieve its goals. In a new work appearing online Wednesday in ...
In our bodies, there are trillions of cells. From white blood cells to skin cells, each type has its own specific function which helps us perform tasks and survive. But what makes up these cells and ...
