Provide some examples of proteins that undergo post-translational modification. What are the protein targets, the type of reaction, and purpose or functions of this post-translational modification, then look up other resources to find other functions of lysyl-tRNA synthetase and explainarrow_forwardTRNAS are 'charged' or activated by aminoacyl TRNA synthetases. Select the correct statements regarding this process. The process is dependent on interactions between ribosomes and aminoacyl TRNA synthetases. The aminoacid is added to the D-loop of the tRNA. Aminoacyl TRNA synthetases are pre-associated with tRNAS. The amino acid is attached to the terminal to the 3' hydroxyl of an adenine in the acceptor arm. The process requires an aminoacyl-adenylate intermadiate. QUESTION 19 Select the correct statements regarding myosin-mediated contraction the sarcomere. O Ca2+ is required for the binding of myosin to f-actin. Myosin and f-actin are randomly distributed in the sarcomere. Physical pulling of the actin microfilament requires three distinct conformation changes on myosin that involve ATP binding, ATP hydrolysis and sequential release of inorganic phosphate and ADP. Myosin-mediated contracted is ubiquitous across all cell types. O O O Oarrow_forward
