Name _____________________________ Class __________ Date __________ The Genetic Code 1. Genetic information is stored and transmitted within A. nucleic acids. B. proteins. C. amino acids. D. sugars. 2. Each group of three mRNA bases specifies a particular A. nucleic acid. B. protein. C. amino acid. D. gene. Use the diagram to answer Questions 3–7. 3. Which two mRNA codes correspond to histidine (His)? Name _____________________________ Class __________ Date __________ 4. How many different mRNA codes correspond to arginine (Arg)? 5. How many different mRNA codes correspond to methionine (Met)? 6. Which of the following codons signifies the end of translation? A. CAA B. UGA C. AUC D. CCA 7. Which of the chains of amino acids corresponds to the nucleotide sequence UCA-AGCGUA? A glu-cys-pro B glu-asp-“stop” C thr-arg-met D ser-ser-val 8. What is the genetic code? How is the genetic code similar to a “language”? Name _____________________________ Class __________ Date __________ 9. A researcher identifies the nucleotide sequence AAC in a long strand of RNA inside a nucleus. In the genetic code, AAC codes for the amino acid asparagine. When the RNA becomes involved in protein synthesis, will asparagines necessarily appear in the protein? Explain your answer.
