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 ...

A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA. Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes.

Prokaryote DNA is usually found as a single chromosome of circular DNA. These organisms also lack other membrane-bound structures such as the endoplasmic reticulum. No, prokaryotes do not have ...

Scientists from Flinders University in Australia have made a surprising discovery about a recently identified type of genetic material called circular RNAs. Their research suggests that these ...

DNA (deoxyribonucleic acid), the molecular "blueprint" carrying the genetic instructions that influence the growth, ...

circular DNA structures that are common in some of the most difficult to treat cancers. The papers identify, for the first time, how to specifically target cancer cells containing this malignant ...

These days, scientists sometimes take a minimalist approach, throwing out the cell and its contaminating components altogether and keeping only what they need for transcription and translation. Such ...

Prof. Burstein explains, "Plasmids are small, circular, double-stranded DNA molecules classified as 'mobile genetic elements.' Like viruses, plasmids move from one cell to another, but unlike ...
