DNA is a modern drama in 14 short scenes. It revolves around the 'accidental' torture and murder of a teenage boy named Adam, which has happened just before the events of the play. The subsequent story concerns the guilty teenagers' efforts to cover up their crime and move on with their lives. This group consists of ten members:

Leah - Easily the most vocal of the group. Usually seen with Phil, the quietest. Leah is intelligent, but unsure of herself. A moral girl.

Phil - Always using his mouth, but usually to eat. Rude to Leah. Whenever he speaks, he displays a sinister intellect.

Mark & Jan - Never apart, Mark and Jan give the audiences clues through their inferences. Easily led. Low moral fiber.

Brian - Sensitive. Cries for much of the play and is forced to go along with the plans. Anti-depressants utterly change his behaviour.

John Tate - Apparently new to the school and a bully. Cannot handle the stress of events and eventually turns to Jesus.

Cathy - Sociopath who is more excited than repulsed by events. A willing participant in all the worst aspects of the play.

Richard - A lesser character. Acts tougher than he is. Usually paired with Brian as a handler.

Danny - Lesser character. Future dentist, more obsessed with his prospects than any moral concerns.

Lou - Mostly an onlooker, though goes along with the plan. Highly repetitive.
