Demonstrate understanding of gene expression
This standard is about understanding how genes are expressed — how the instructions in your DNA actually get turned into proteins and how those proteins affect what you look like and how your body works. You need to understand the key steps from DNA to protein, explain how genes control body functions through proteins, and describe how both genes and environment work together to create your traits.
You can define key terms, identify the steps of protein synthesis from DNA to protein, and describe what gene expression means using correct biological language.
You explain the detailed mechanisms — how DNA sequence determines protein structure, how enzymes control metabolic pathways, how the amount of proteins produced affects phenotype, and how environment influences expression without changing genes.
You can link different biological ideas together — comparing how different genes and metabolic pathways work, explaining the relationship between protein amount and phenotype, and analysing how genetic and environmental factors interact to create the observable trait.
