1. A DNA template triplet is CGA. Which mRNA codon is transcribed from it?
RNA uses complementary pairing with U in place of T: C pairs with G, G with C, and A with U.
Use Skill Align for QCE Year 12 Biology practice questions after the relevant science concept, data skill, or investigation skill has been taught.
QCE Year 12 Biology includes 58 practice skills across Cells and internal environment, Biodiversity and ecosystems, Heredity, and Data and inquiry skills.
A practice skill is a focused topic or question type designed to help students practise one curriculum-aligned concept with instant feedback and explanations. Skill Align uses practice skills to organise questions by year level, subject, strand, and curriculum focus.
These sample questions are visible on the page before login. Use them to check the style of the answers and worked explanations, then open the no-login demo for a longer practice set.
RNA uses complementary pairing with U in place of T: C pairs with G, G with C, and A with U.
The Bb parent can pass B or b, while the bb parent passes b. Half the boxes are bb.
Vaccine antigens can trigger lymphocyte activation and memory-cell formation without causing the full disease.
When each case causes fewer than one new case on average, the outbreak declines over time.
Small DNA fragments move more easily through the gel and travel further from the wells.
Glucagon stimulates release of glucose into the blood, helping return levels toward normal.
Year 10 practice can help identify whether a student is comfortable with algebra, geometry, trigonometry, statistics, and probability before choosing senior maths pathways. The demo is a quick way to sample those areas without creating an account.
These related pages help students and parents move from this search result to the exact year, state pathway, or subject they need.
Year 12 Biology practice sits inside QCE Biology Unit 1 to Unit 4 coverage for cells, internal environment, biodiversity, ecosystems, heredity, continuity of life, data interpretation, and working scientifically, with Skill Align keeping the route focused on this senior year level.
Senior practice is organised by year level, topic, and mode so students can revise targeted areas rather than sitting a full-paper workflow every time.
Start with the public sample questions to check the question style, then use the curriculum coverage page to choose a topic that matches the student's current classwork.
These examples are not the full topic list. Use the curriculum coverage page for the complete mapped pathway.
Queensland students studying Year 12 Biology.
Yes. Public sample pages let visitors preview curated Skill Align questions without creating a saved student test record.
No. Skill Align is designed for structured practice after students have learned topics at school or with a teacher.
Yes. Skill Align uses subject-based access, so families can start with the year level and subject the student needs now.
