29. The top diagram is of a transcription. Select DNA template used in transcription of mRNA. a) strand A c) both A and B are templates b) strand B d) neither A nor B 30. DNA polymerase unlike RNA polymerase a) catalyzes formation of phosphodiester bonds b) uses deoxyribonucleotides c) catalyzes synthesis of a new DNA strand in 5' - 3' direction d) B and C e) A, B and C 31. The strain of E. coli is resistant to antibiotic tetracycline. The resistance gene is on E. coli's plasmid. Assume that tetracycline resistant E. coli was mixed with Staphylococcus aureus. The mixed population continues growing and reaches stationary phase. Is it possible that S. aureus develops resistance to tetracycline? a) Yes, but only if mutation occurs in S. aureus transport mechanism gene. b) Yes. S. aureus cells could become transformed with E. coli plasmids. c) Yes. S. aureus cells could obtain E. coli plasmid through conjugation. d) No, because they are different bacterial species. 32. Transcription is the process that in bacterial cells creates a) RNA molecules b) proteins c) enzymes d) B and C 33. During DNA replication single nucleotide got deleted. The nucleotide was within the second codon of a gene that encodes an enzyme. What will the consequence of the deletion of a single nucleotide on gene expression be? a) Encoded enzyme will have one less amino acid b) Encoded enzyme will have amino acid sequence that differs from the un-mutated, but will maintain the properties of an enzyme. c) The protein product will have different amino acid sequence and will not act as an enzyme d) Encoded enzyme will differ from un-mutated version in one amino acid only 34. Bacterial virus, bacteriophage, is essential for a) bacterial transformation process c) bacterial transduction b) bacterial conjugation d) bacterial replication 35. Streptococcus pyogenes is β hemolytic microorganism. When grown on sheep blood agar plate the colonies of this microorganism a) form cloudy, olive green zone around each colony b) excrete hemolysins c) do not create distinct zone around colony d) A and B e) B and C
