Key Themes & Exam Technique
Theme: Guilt and Responsibility
Guilt is the engine that drives DNA. Every character responds to it differently, and Kelly uses these varied responses to explore the full spectrum of moral failure. Phil suppresses guilt through emotional shutdown — he eats, stays silent, and treats the crisis as a logistical problem. Leah expresses guilt through her monologues, talking incessantly about bonobos and happiness as though philosophical reflection can substitute for moral action. Cathy appears to feel no guilt at all, relishing the excitement of the cover-up and the violence that follows.
The play’s most important insight about guilt is that responsibility is diffused across the group. Nobody feels individually accountable because they all participated together. John Tate bans the word “dead” to avoid confronting guilt. Brian breaks down but does not confess. Richard questions Phil but does not leave. Kelly shows that collective guilt is more dangerous than individual guilt, because within a group, everyone can convince themselves that someone else is really to blame.
Kelly presents guilt as something the group diffuses rather than confronts. Each character avoids responsibility differently: Phil through silence, Leah through talk, Cathy through enthusiastic participation, John Tate through denial, Brian through breakdown, and Richard through unanswered questions.
Theme: Leadership and Power
The leadership succession in DNA — John Tate to Phil to Cathy — is one of its most important structural patterns. John Tate leads through bluster and denial, which collapses under pressure. Phil leads through silence and cold efficiency, which is effective but amoral. Cathy leads through violence and intimidation, which is the play’s endpoint of moral deterioration.
Kelly suggests that without external moral authority (there are no adults in the play), leadership gravitates to whoever is willing to be the most ruthless. The group does not choose its leaders consciously; leaders emerge because they fill the vacuum created by the previous leader’s failure. This is a deeply pessimistic view of power dynamics — it implies that in any group, given enough pressure, the cruellest person will eventually take charge.
Peer pressure operates on two levels in the play. On the surface, it drives the bullying of Adam — each member of the group participates because the others do, and nobody wants to be the one who refuses. Below the surface, it drives the cover-up. Once Phil devises his plan, the group follows because the social cost of refusal — isolation, exposure, being the outsider — feels worse than the moral cost of complicity.
Adam is the play’s most extreme victim of peer pressure. He endured bullying because he wanted to belong: he stole vodka, ate leaves, walked across a grille, all because the group told him to. His desperation to fit in led directly to his fall. Kelly presents a devastating irony: Adam’s need to belong is what destroys him, and the group’s need to hold together after his fall is what destroys their morality.
Theme: Silence and Complicity
Silence takes many forms in DNA. Phil’s silence is strategic power. Adam’s silence is imposed powerlessness. The group’s silence (nobody goes to the police) is complicity. Leah talks endlessly but might as well be silent, because nobody listens. The play argues that silence is not neutral — choosing not to speak when something is wrong is itself a moral choice, and a damning one.
Kelly extends this to the audience. We watch the play, we see the horror unfold, and we do nothing — because we cannot. But the discomfort we feel is exactly the point. Kelly wants us to recognise that we, too, are bystanders. The play’s lack of resolution — no confession, no punishment, no redemption — refuses to let us off the hook. We leave the theatre as complicit in our inaction as the characters in theirs.
The five key themes of DNA are: guilt and responsibility (diffused across the group), leadership and power (declining succession), peer pressure (drives both bullying and cover-up), silence and complicity (choosing not to act is a moral choice), and morality (conscience without action is useless).
Exam Technique: The Comparison Question
Your paper may give you an extract from DNA alongside an unseen extract from another modern play and ask you to compare how both writers present a theme, character type, or dramatic effect. Treat this as a comparative analysis task, with language, structure and context all under test. Check your exam board’s specimen paper for the exact question wording, mark weighting and recommended timing.
The key to a strong comparison is comparative analysis — not writing about one text then the other, but weaving them together. Use connecting phrases: “Similarly, the unseen writer uses…” “In contrast, Kelly presents this through…” “Both writers use fragmented dialogue, but where Kelly’s creates panic, the unseen writer’s creates…”
A whole-text question asks a broader question about DNA as a whole. Plan to cover at least three moments from different parts of the play, showing you know the text from beginning to end. Structure your response around the question’s key concept (e.g. leadership, violence, silence) and use well-chosen evidence including precise quotations.
For AO1, make clear points about the play’s meaning. For AO2, analyse Kelly’s methods — his use of silence, fragmented dialogue, offstage violence, the three locations, the leadership succession. For AO3, embed relevant context: the 2007 premiere, youth violence, Milgram, the Stanford Prison Experiment, the bystander effect. The best essays integrate all three assessment objectives within each paragraph, not in separate sections.
A strong essay on DNA will argue that Kelly’s play is not about one group of teenagers but about human nature itself. The non-specific setting, the universal themes, and the deliberate refusal of resolution all point to a writer who believes that the potential for moral collapse exists in every group and every individual. The question is not whether it will happen, but what we do when it does.
