Which level of protein structure is disrupted through the hydrolysis of peptide bonds? Quaternary Tertiary Primary Secondary - ANSWER Primary The primary structure of a protein is the sequence of amino acids held together by peptide bonds. Peptide bonds are formed by dehydration reactions and disrupted by hydrolysis. A mutation in the beta-hemoglobin gene, which results in the replacement of the amino acid glutamate in position 6 with the amino acid valine, leads to the develop...

Question : The major impact of the physiological changes that occur with aging is: Student Answer: Reduced physiological reserve Instructor Explanation: The major impact of all of these physiological changes can be highlighted with three primary points. First, there is a reduced physiological reserve of most body systems, particularly cardiac, respiratory, and renal. Second, there are reduced homeostatic mechanisms that fail to adjust regulatory systems such a...

You discover a new bacterial operon that is induced by the presence of lead. You find a mutation that results in a mutation in the operator that changes the binding sequence so that the repressor is always bound to it. Would this mutation be rescued by a plasmid with a wild type copy of the operon and why? correct answers Yes, because the repressor would still be able to bind to the operator in the plasmid allowing for normal expression from the plasmid Why is it difficult to find a treatment...
