B12/L3 - DNA & Human Genome Lesson Worksheet With Answers / GCSE / AQA/ Combined Science

This GCSE Combined Science Biology (AQA B12: DNA and the Genome) worksheet combines scientific literacy with curriculum-aligned content on DNA, genes, and the Human Genome Project. It is a full resource that requires no additional resources and can be printed as a small a5 booklet and completed in books or on paper.

Students read clear, accessible passages before answering recall questions and then tiered comprehension questions that build from recall and understanding to application and evaluation. The activity promotes accurate scientific writing and supports the literacy focus of the science curriculum. All answers can be found in the text so it is accessible to all students with extension tasks and more challenging questions for higher classes.

A WWW and EBI activity is found at the end to allow for active self evaluation at the end of the activity. This worksheet also provides an answer section, making it ideal for cover teachers, self-assessment, or independent learning. It can be used a lesson in itself or as a revision lesson where students have already come across the content.

This worksheet is perfect for:

Cover lessons – everything is self-contained with clear instructions and a full answer section.

Independent learning or homework – students can complete the reading and tasks at their own pace.

Literacy-focused science lessons – strengthens scientific vocabulary, reading comprehension, and extended writing.

Revision or consolidation – ideal for revisiting the DNA and Genome topic before assessment.

Differentiated classrooms – all answers are in the text, supporting lower-ability learners, while extension tasks challenge higher-tier students.

Assessment for learning (AfL) – the built-in WWW/EBI reflection supports self-evaluation and teacher feedback.

These resources are designed to minimise printing, allowing teachers to reuse sheets while students complete all tasks in their exercise books or on separate paper.
