Multicopy single-stranded DNA (msDNA) is a type of extrachromosomal satellite DNA that consists of a single-stranded DNA molecule linked via a phosphodiester bond to a branched RNA molecule. The resultant structure possesses two stem-loop structures, and functions as both a primer and a template for the creation of more msDNA. It is known to encode a type of reverse transcriptase. Its function remains unknown even though many copies are present within cells.
