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...

CBE 555"Which of the following statements are correct? Explain your answers. A. A DNA strand has a polarity because its two ends contain different bases. B. G-C base pairs are more stable than A-T base pairs." - correct answer "A. False. The polarity of a DNA strand usually refers to the orientation of its sugar-phosphate backbone: one end contains a phosphate group, the other end contains a hydroxyl group. B. True. G-C: 3 H-bonds vs A-T: only 2 H-bonds " "Histone proteins are among t...

Where does translation always start? correct answers cytoplasm Do proteins destined for the nucleus (eg TF) also get translated in the cytoplasm? correct answers Yes, they must exit the nucleus to get translated and then get transported back into the nucleus What strategies do you think the cell can use to get proteins to the right place within the cell? correct answers - protein tagging What mechanisms do cells use to transport proteins to the right place within the cell? correct answe...
