Single-stranded circular DNA (ss-circular DNA) is a type of genetic material characterized by its circular shape and the presence of only one strand, as opposed to the more common double-stranded form. This structure is particularly relevant in certain viruses and plasmids, where it plays a crucial role in their replication and functioning. In the context of plant viruses, ss-circular DNA contributes to understanding how these pathogens operate and propagate within host plants.
congrats on reading the definition of single-stranded circular DNA. now let's actually learn it.
