The particles are about 18-19 nm in diameter and contain 6-8 short segments (~ 1kb) of single-stranded DNA. The DNA enters the cell nucleus and is transcribed first into double stranded DNA and subsequently into mRNA for translation into proteins.

Currently, the following species have been entered into the system:
