AP Biology · Unit 6: Gene Expression and Regulation

6.6 Gene Expression and Cell Specialization

In short

You are expected to understand the mechanisms of gene expression regulation, specifically how RNA polymerase and transcription factors bind to promoter or enhancer sequences (which can be upstream or downstream) to initiate transcription. You must also understand how negative regulatory molecules can block transcription.

What else do you need to know about Gene Expression and Cell Specialization?

Furthermore, you need to connect these regulatory mechanisms to differential gene expression, cell specialization, and the resulting phenotypic differences in cells and organisms. The role of small RNA molecules in gene regulation is also required knowledge. There are no specific exclusion statements for this topic.

How is Gene Expression and Cell Specialization tested on the exam?

This topic is assessed with a focus on the suggested skill 6.B: 'Support a claim with evidence from biological principles, concepts, processes, and data.' Exam questions may require you to explain the effects of transcription factor binding on gene expression and phenotype, or to connect gene regulation to phenotypic differences in cells and organisms. The primary command word associated with the learning objectives is 'Explain'.
