Single-stranded DNA

Single-stranded DNA (single-stranded DNA) to most of the DNA double helix structure, but once or heat processing base will become a single-stranded state. Single-stranded DNA refers to the existence of such a state of the DNA. Single-stranded DNA molecule in the fluid nature of the absorption spectrum, the base nature of the response, and so on are different and the double-stranded DNA. Some of the phage particle contains a single circular chain of DNA, this kind of phage DNA in the cell proliferation when the formation of double-stranded DNA.
