Infer: Why do you think stop and start codon signals are necessary for protein synthesis?
Summarize: How do genes determine the traits of an organism? Explain in detail.
• Think and discuss: Consider the two following statements:
• The theory of evolution states that all living things had a single common ancestor.
• The translation between mRNA and amino acids is the same for all living things. (For example, the mRNA codon CAG codes for glutamine in all living things.)
Does the second statement support the theory of evolution? Explain why or why not.
If possible, discuss your answer with your teacher and classmates.
