Translation of RNA to Protein Quiz 1. True or False: Ribosomes are the organelles where proteins are made. true 2. True or False: Translation translates from one language to another. true 3. How does a tRNA interact with the mRNA? The anticodon at the bottom of a tRNA molecule binds to the codon of an mRNA strand. This occurs in the ribosome. 4. What is a stop codon? How many stop codons are there? There are three stop codons. They do not code for an amino acid, but instead signify the end of translation. 5. How many amino acids are used to make proteins? There are 20 amino acids used to make proteins. 6. During translation, the mRNA is translated from __________ into __________. a) nucleic acid, amino acids b) nucleotides, protein c) nucleotides, amino acids d) nucleic acid, protein 7. What is the role of the tRNA molecules? a) The tRNA determines the order of the amino acids in the protein. b) The tRNA reads the mRNA code and brings a specific amino acid to the ribosome. c) The tRNA brings the genetic message to the ribosome from the nucleus. d) all of the above 8. What is the sequence of the anticodon that binds to a CUA codon? a) GAU b) GAT c) CUA d) CTA 9. Which of the following statements concerning codons is true? a) Codons are read in the ribosome. b) Codons are found in the mRNA sequence. c) Codons consist of three RNA bases. d) All of the above statements are true. 10. GGG codes for glycine and CCC codes for Proline. If the sequence within a gene is GGGGGGCCCGGGCCC, what is the amino acid sequence of the corresponding protein? a) Gly-Gly-Pro-Gly-Pro b) Pro-Pro-Gly-Pro-Gly c) Gly-Gly-Pro-Pro-Gly d) Pro-Pro-Gly-Gly-Pro
