Circular Single-Stranded DNA (ssDNA) Viruses: Viruses that possess a closed, circular single-stranded DNA genome and typically replicate via the rolling circle mechanism.

While our own DNA is linear, circular DNA is common in the genomes of bacteria and viruses. Scientists have also discovered circular DNA within the nuclei of human and plant cells, called ...

“We also want to conduct more detailed research into the origins of circular DNA in order to better understand why it is that children develop cancer,” says Dr. Henssen. Reference: Koche RP et al.

We've known that circular RNAs show up in DNA viruses like Epstein-Barr and the human papillomavirus, but seeing that they are generated by an RNA virus like HIV-1 is incredibly exciting.

A study of newly created databases of medulloblastoma has found that patients with tumors containing circular extrachromosomal DNA - loops of DNA found outside of regular chromosomes - are twice ...

Their findings, which were published March 7 in Science, one of world’s leading scientific journals, not only reveal new details about how secondary DNA structures like G4s can impede DNA replication, ...

Protein involved in balancing DNA replication and restarting found USP50 protein helps balance nuclease and helicase activity during critical processes Date: October 14, 2024 Source: University of ...

The researchers also discovered that overactive genes within abnormal circular DNA structures in tumor cells genes drive bladder cancer resistance to therapy.

Technology DNA nanobots can exponentially self-replicate Tiny machines made from strands of DNA can build copies of themselves, leading to exponential replication. Similar devices could one day be ...
