GENE EXPRESSION
FIGURE 13–9 DNA carries information for specifying the traits of an organism. The cell uses the sequence of bases in DNA as a template for making mRNA. The codons of mRNA specify the sequence of amino acids in a protein. Proteins, in turn, play a key role in producing an organism's traits.
dReview How does a cell interpret the genetic code?
Explain What are codons and anticodons?
Apply Concepts Using the table in Figure 13–6, identify the amino acids specified by codons: UGG, AAG, and UGC.
Review What happens during translation?
Compare and Contrast How is protein synthesis different from DNA replication? (Hint: Revisit Lesson 12.3.)
Review Why is the genetic code considered universal?
Explain What does the term gene expression mean?
Infer In what way does controlling the proteins in an organism control the organism's characteristics?
Apply the Big idea
Choose one component of translation to consider in depth. For instance, you might choose to consider one form of RNA or one step in the process. Then write a question or a series of questions about that component. Select one question, and use it to form a hypothesis that could be tested in an experiment.
