Question

27. Alpha-helices and beta pleated sheets represent which structural level of proteins? A. primary B. secondary C. tertiary D. elementary E basal 28. Which of the following is the first step in translation? A Small 40S ribosome subunit with initiation factors binds to the 5' cap of the mRNA and scans for the start codon. B. The RNA carrying Methionine binds to the P site and the large 60S subunit binds to form the complete ribosome. C. Elongation factors deliver a tRNA with the appropriate amino acid to the A site. D. A peptide bond is formed between amino acids and the growing peptide is passed from the exiting tRNA to the tRNA entering the P site E. Translation continues until a stop codon is reached and release factors bind to the A site thereby halting translation 29. Which of the following are advantages of polyploidy? A. Multiple copies of each gene B. The opportunity for redundant alleles to gain new functions by mutation C. Larger plant organs D. All of the above E. None of the above 30. Which method of genome sequencing involves fingerprinting thousands of BAC libraries to develop a minimum tiling path (MTP) followed by DNA sequencing of the MTP? A. shotgun sequencing B. BAC by BAC sequencing C. chromosome flow sorting D. Ac/DS transposition E. Robertsonian translocation 31. Which method of genome sequencing involves fragmentation of the genome followed directly by DNA sequencing and assembly? A. shotgun sequencing B. BAC by BAC sequencing C. chromosome flow sorting D. Ac/DS transposition E. Robertsonian translocation 32. What is used to cut the genome into smaller fragments with "sticky ends" for the construction of Bacterial Artificial Chromosomes? A. UV radiation B. flow sorting of chromosomes C. sonication D. restriction enzymes E. Ethylmethane sulfonate (EMS)
