Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by ...

Loss of an enzyme necessary for a process called lipoylation disrupts the way cancer cells copy their DNA, increasing their ...

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 ...

Researchers at The University of Texas MD Anderson Cancer Center have developed a new imaging method, known as RF-SIRF, that ...

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 ...

From the first unzip of the double helix to the final joining of DNA fragments, replication is a carefully coordinated process. Understanding it helps explain how life preserves its genetic code with ...

Researchers at The University of Texas MD Anderson Cancer Center have identified a key enzyme—RNase H2—that helps ...

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 ...

DNA is more than just the iconic double helix we learned in school—it's a dynamic, complex structure at the heart of life. From high-speed replication to advanced sequencing technologies, scientists ...
