🎯 How to Get a Grade 9 in DNA

Before diving into quotes and themes, let’s look at what examiners want for a top-band answer:

• Close analysis of language and structure.

• Clear understanding of characters and themes.

• Judicious use of quotations to support points.

• Evaluation of the play’s context, purpose, and impact on the audience.

• A confident, original personal response.

🔥 Top Themes in DNA

Let’s explore the most important themes that come up time and time again in the exam—and the key quotes to go with them.

---

1. Guilt and Responsibility

The group’s reaction to Adam’s “death” drives the play. Characters either accept guilt, deny it, or become numb to it.

📌 Key Quotes:

• “We did it. We did this to him.” – Leah

  Leah’s directness stands out here. She’s the moral voice of the play, and her simple repetition highlights the inescapability of their guilt.

• “I’m in charge. Everyone is happier. What’s more important: one person or everyone?” – Phil

  This line justifies the group’s actions in a chilling way. Phil suggests that a lie is better than the truth if it keeps the group stable—a key moment in the play’s ethical debate.

💡 Grade 9 Tip:

Explore how different characters respond to guilt: Leah speaks up, Phil stays silent, and Cathy becomes more violent. This shows how guilt can be suppressed or redirected in toxic group dynamics.

---

2. Leadership and Power

Power struggles define the group. As the leader, Phil exerts control through silence and intimidation.

📌 Key Quotes:

• “Phil? Phil?” – Repeated by multiple characters

  The repetition of Phil’s name, especially in times of crisis, shows how dependent the group becomes on him. His silence becomes power.

• “If you go now and you say nothing to anyone, you’ll be fine.” – Phil

  This line is chilling because it shows how Phil manipulates others to maintain control.

💡 Grade 9 Tip:

Comment on non-verbal power. Phil says very little but controls everything. This is a clever structural technique by Kelly—use it to show you can analyse both dialogue and stagecraft.

---

3. Peer Pressure and Conformity

The groupthink mentality pushes characters to do unspeakable things.

📌 Key Quotes:

• “Better than ordinary. You’re not ordinary.” – Leah to Phil

  Leah’s desperation to belong—and to make Phil acknowledge her—shows how peer pressure distorts identity.

• “You crying little piece of filth.” – Cathy to Brian

  Cathy bullies Brian into silence, showing how emotional manipulation is used to keep the group together.

💡 Grade 9 Tip:

Compare how Brian, Leah, and Cathy deal with pressure. Brian cracks, Leah leaves, Cathy becomes more extreme. This gives you a sophisticated argument.

---

4. Morality and Human Nature

DNA suggests that morality can be overridden by group survival. Kelly seems to ask: Are we naturally good or evil?

📌 Key Quotes:

• “It’s either you or him.” – Phil

  A brutal line that reduces morality to survival. It forces the group to choose safety over truth.

• “He’s not dead. He’s alive.” – Brian

  This moment of truth is dismissed. The group would rather keep their story than face consequences.

💡 Grade 9 Tip:

Explore the play’s message: Does Kelly believe people are evil, or that they become evil under pressure? This helps you evaluate the writer’s intentions—a top-band skill.

✍️ How to Use Quotes Effectively in the Exam

The “Zoom-In” Technique

Instead of just stating the quote, zoom in on a word or phrase:

“We did it.” The pronoun “we” highlights collective responsibility, showing that Leah sees guilt as shared rather than individual.

The “Double-Theme” Method

Link quotes to two themes at once for higher marks:

“If you go now…” – This quote shows manipulation and moral decay, as Phil urges silence rather than truth.

---

🧠 Understanding Context in DNA

While DNA is a modern play, it’s not heavily context-based like Shakespeare. But here are some key ideas:

• Post-2000s youth culture: Gang behaviour, bullying, social status.

• Moral ambiguity in society: Reflects a world where truth is often avoided.

• Minimalist drama: Few stage directions and no fixed setting make it a universal and timeless story.

💡 Grade 9 Tip:

Mention that the lack of a clear location or time period makes the message more relevant to any group of people, anywhere.

---

🧪 Structure and Form

Kelly uses minimalism to heighten the tension:

• Short scenes and sparse dialogue make the play fast-paced and intense.

• Monologues (especially Leah’s) create emotional depth.

• Repetition (e.g. “Phil? Phil?”) shows panic, dependency, and fear.

💡 Grade 9 Tip:

Comment on how the form supports the theme—e.g. fragmented speech = fragmented morals.

---

📝 Sample Grade 9 Paragraph (PEEL Structure)

Point: Dennis Kelly explores the theme of guilt through Leah’s emotional monologue.

Evidence: “We did it. We did this to him.”

Explain: The repetition of “we” reinforces collective guilt, suggesting that Leah feels a moral burden that the rest of the group avoids.

Link: This makes her decision to leave the group more powerful, as it shows she’s the only one who refuses to suppress her conscience.
