Scientists have recently been learning more about the importance of small bits of circular genetic material known as ...

Circular single-stranded DNA viruses represent a diverse group of pathogens that possess a covalently closed, circular single-stranded DNA genome. Their small genomes belie a sophisticated replication ...

Small, cancer-associated DNA circles "hitchhike" on chromosomes during cell division to spread efficiently to daughter cells by co-opting a process used to maintain cellular identity through ...

Circular DNA, thought to be an accidental byproduct, is borrowing the cell’s DNA repair mechanisms to copy itself DURHAM, N.C. -- Like its viral cousins, a somewhat parasitic DNA sequence called a ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...

The DNA inside our cells is constantly being damaged, and one of the worst kinds of damage is a double-strand break—when both ...

In September 1970, Janet Mertz joined the biochemistry department at Stanford University. She was one of only six new graduate students in the department and the first female one admitted in nine ...

In a groundbreaking discovery, researchers from Florida Atlantic University's Charles E. Schmidt College of Medicine have identified a never-before-seen mechanism that enables the human ...

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 ...
