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.

Distinct from the intact chromosomes visible underneath the microscope were numerous “very small double chromatin bodies,” which are today better known as extrachromosomal DNA. Thanks to modern ...

The researchers also discovered that overactive genes within abnormal circular DNA structures in tumor cells genes drive ...
