What is ssDNA? The ssDNA definition is as follows: Single-stranded DNA is the single DNA strand that is created during the replication process of DNA. The replication of single-stranded DNA forms two separate single-stranded chromosomes that join together to form double-stranded DNA (dsDNA).

What is ssDNA used for?

Synthesizing ssDNA during DNA replication is important because it allows duplication of genetic material and thus the reproduction of cells. Another role of ssDNA is to aid with DNA repair. DsDNA can be damaged by external factors such as free radicals and radiation.

Which virus has ssDNA?

The ssDNA viruses include 4 families of bacterial and archaeal viruses, Inoviridae, Microviridae, Pleolipoviridae and Spiraviridae, and 9 families of eukaryotic viruses: Anelloviridae, Bacilladnaviridae, Bidnaviridae, Circoviridae, Geminiviridae, Genomoviridae, Nanoviridae, Parvoviridae and Smacoviridae.
