The CFTR protein is made up of 1,480 amino acids linked together in a chain. Some humans produce a version of the CFTR protein in which phenylalanine (an amino acid) has been deleted from position 508 of the amino acid chain. ‘Which of the following best predicts how the amino acid deletion will affect the structure of the CFTR protein? @ It will have no observable effect on the structure of the CFTR protein. It will affect the primary structure of the CFTR protein, but the other levels of protein structure will not be affected. @ It will affect the secondary and tertiary structures of the CFTR protein, but the primary structure will not be affected. Wﬂmmmtem 4. Bacteriophages are viruses that infect bacteria. In an experiment, bacteriophages were labeled with either radioactive phosphorus or radioactive sulfur. The labeled bacteriophages were incubated with bacteria for a brief amount of time and then removed. The infected bacteria cells were found to contain significant amounts of radioactive phosphorus but not radioactive sulfur. Based on the results of the experiment, which of the following types of molecules did the bacteriophages most likely inject into the bacteria cells? @ Simple carbohydrate Amino acid @ Polypeptide Copyight 2017 The Colleg Bonrd.
