Quiz 10 Ch 10 Name________________________ Remote # ____________ 1. Which of the following is an accurate What sequence of the anticodon would statement concerning the differences decode this codon? Explain your answer. between DNA and RNA? a. ATG, because the anticodon is a. RNA is usually double-stranded, but DNA complementary to the template strand is usually single-stranded. b. AUG, because the anticodon is b. RNA has the sugar deoxyribose, but DNA complementary to the template strand has the sugar ribose. c. UAC, because the anticodon has the c. RNA contains three different nucleotides, same sequence as the template strand (but but DNA contains four different nucleotides. it has U instead of T) d. RNA lacks the base thymine (which is d. TAC, because the anticodon has the found in DNA) and has uracil instead. same sequence as the template strand 2. The process of RNA synthesis is called 5. What is the promoter region? __________. a. It is a region of RNA that binds to the a. transcription RNA polymerase and initiates transcription. b. translation b. It is a component of each type of RNA. c. replication c. It is responsible for the selective nature of d. mutation transcription. d. It is a region of a parent DNA strand that 3. The cells in your skin have a different binds to the RNA polymerase and initiates shape and different function from the cells in transcription. your liver because the two types of cells have different __________. 6. RNA ____________________ is the a. DNA molecule that is responsible for synthesizing b. proteins each form of RNA. c. lipids a. promoter d. carbohydrates b. polyurethane c. polyp 4. Imagine that a codon in the template d. polymerase strand of a gene has the sequence TAC. 1 7. ____________________ is the type of RNA the ribosome that carries a specific amino acid to the b. takes part indirectly in protein synthesis; ribosome. the DNA itself stays in the nucleus a. tRNA c. has nothing to do with protein synthesis; it b. mRNA is involved only in cell division c. rRNA d. is involved in protein synthesis within the d. DNA nucleus e. codes for mRNA but not for tRNA or 8. Which of the following is a single- rRNA stranded molecule that contains the information for assembly of a specific 11. Synthesis of a protein based on the protein? sequence of messenger RNA a. transfer RNA a. is catalyzed by DNA polymerase b. messenger RNA b. is catalyzed by RNA polymerase c. exon DNA c. is called translation d. intron DNA d. is called transcription e. ribosomal RNA e. occurs in the nucleus 9. Anticodon is the term applied to 12. A Barr body is: a. the list of amino acids that corresponds to a. a condensed X chromosome the genetic code b. an organelle involved in protein synthesis b. the concept that multiple codons c. another term for chromosomes as they sometimes code for a single amino acid are seen during cell division c. the part of the tRNA that interacts with the d. visible in cells of both males and females codon e. present only in males, because their d. the several three-nucleotide stretches female chromosomes are inactivated that code for "stop" e. the part of the tRNA that binds to an amino acid 10. DNA a. takes part directly in protein synthesis by leaving the nucleus and being translated on 2
