AP Biology Reading Guide Chapter 15 and 16: Regulation of Gene Expression & Development, Stem Cells and Cancer. Compare and contrast the lac operon and the trp operon. (Remember that compare means “to tell how they are similar,” and contrast means “to tell how they are different.”) Lac is inducible and trp operon is repressible. They both have the three components of an operon: an operator, promoter, and regulatory gene. They are different because the trp repressor is inactive alone ...

Gene Expression—Transcription How is mRNA synthesized and what message does it carry? Why? DNA is often referred to as a genetic blueprint. In the same way that blueprints contain the instructions for construction of a building, the DNA found inside the nuclei of cells contains the instructions for assembling a living organism. The DNA blueprint carries its instructions in the form of genes. In most cases the genes direct the production of a polypeptide, from which other more complex ...
