Name _____________________________ Per _________ A BIO Ch 11 Test – DNA, RNA & Protein Synthesis Review Sheet QUESTIONS 1. Molecules of DNA and RNA are made of chains of this monomer 2. List the three parts of a nucleotide 3. DNA is named for which part of the molecule it contains (hint: RNA contains a different one of these) 4. What two scientists are given credit for determining the structure of DNA? 5. What are the two base-pairing rules for DNA? 6. Build the bottom side of the DNA molecule on the right: 7. The enzyme that builds new strands of DNA during replication is 8. What are three differences between DNA and RNA? 9. List the three types of RNA 10. List the functions of the three types of RNA you just answered in #9 11. Where does DNA replication take place? 12. What are the two stages of protein synthesis? 13. What molecule is made during transcription? 14. What molecule is made during translation? 15. Where does transcription occur? 16. Where does translation occur? 17. A mRNA triplet that codes for one amino acid is called a? 18. What is this a picture of? ANSWERS G C T A G C C A T C G A 19. What process is this a picture of? 20. What is happening in #19? For 21- 30, Choose DNA, RNA or Both: 21. Contains deoxyribose sugar 22. Can be found in the nucleus of the cell 23. Has three different types 24. Contains ribose sugar 25. Contains Uracil (U) as one of its bases 26. Is double-stranded 27. Contains Thymine (T) as one of its bases 28. Is involved (used or made) during transcription 29. Is involved (used or made) during translation 30. Contains Adenine (A) as one of its bases For 31- 38, Choose DNA Replication, Tanscription, Translation, Both Replication and Transcription, or Both Transcription and Translation: 31. Occurs in the nucleus 32. The two stages of protein synthesis 33. Process where mRNA is “decoded” into a chain of amino acids 34. Process where DNA is copied into two identical molecules of DNA 35. This process involves tRNA carrying amino acids to ribosomes 36. Process where DNA is used to make mRNA 37. Process that occurs during the S phase of the cell cycle 38. Process that occurs at ribosomes 39. Given the following strand of DNA, construct the complimentary mRNA molecule that would be made during transcription: DNA strand: TAC – GCA - TGG – AAA – GGG – CGG – ACT mRNA strand: ____ - _____ - _____ - _____ - _____ - _____ - _____ Next, use the decoder chart below to write the corresponding amino acids that would be coded for by the mRNA that you created: Amino acids: ______ - _______ - _______ - _______ - _______ - _______ - _____ 40. If there were a mutation in the original DNA sequence above where the first G was deleted, what would happen to the protein that would ultimately be made?
