1. The protein-synthesis model shows mRNA codon UUU. Which amino acid information carrier is read at the ribosome?
The ribosome reads mRNA codons during translation to assemble a polypeptide.
Use Skill Align for WACE Year 12 Biology practice questions and exercise questions after the relevant science concept, data skill, or investigation skill has been taught.
WACE Year 12 Biology includes 63 practice skills across Ecosystems and biodiversity, Cells and systems, Heredity and biotechnology, and Evolution, homeostasis and disease.
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.
The ribosome reads mRNA codons during translation to assemble a polypeptide.
Each offspring receives T from one parent and t from the other, so all are heterozygous Tt.
If each infected person infects more than one new person on average, case numbers can increase.
The shape of an antibody binding site determines which antigen it binds most effectively.
Inheritance evidence in a gel profile is supported when child bands can be accounted for by the parent lanes.
The frequency increased from 0.30 to 0.55, so allele B became more common in the population.
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 WACE Biology Unit 1 to Unit 4 coverage for ecosystems, biodiversity, cells, multicellular systems, heredity, biotechnology, evolution, homeostasis, disease, environmental response, and inquiry skills, 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. Skill Align treats practice questions and exercise questions as the same learning workflow: students answer curriculum-aligned questions, review explanations, and move between exercise mode and test mode.
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.

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. Families may search for either wording; Skill Align uses one curriculum-aligned practice page for both practice questions and exercise questions.
Yes. Skill Align uses subject-based access, so families can start with the year level and subject the student needs now.
