3 Question #2 Which of the following will NOT be a DNA sequence for valine? CAT GTA CAC CAG

4 Question #3 Which of the following are NOT complementary? AGT and TCA
GCA and CGU TCA and AGU GAT and CTU

5 Question #4 Which of the following are true about amino acids? Write in ALL that apply. Most come from the food you eat. They are held together in a protein by peptide bonds. Your body makes them as needed. There is no amino acid for the sequence ATC.

6 Question #5 How many tRNAs are needed for the following mRNA sequence: AUG CAC GGA UAA? One Two Three Four

7 Question #6 Which of the following is part of a charged tRNA? Write in ALL that apply. mG cap Amino acid Anticodon Poly-A tail

10 Question #9 Peptide bonds are formed during transcription
RNA processing translation All of these

11 Question #10 Which of the following is true of mutations? Write in ALL that apply. They can occur during transcription They are mistakes in DNA sequences They can be removed through RNA processing They are called introns They result in the formation of incorrect proteins
