[{'content': "Which of the following group of proteins assist in the 'folding' of other proteins \nSelect and explain. \nA. Proteases, B. Proteosomes, C. Templates, D. Chaperones", 'role': 'user'}, {'content': "Answer: D \nExplanation: Chaperones are proteins that play a role in the assembly or proper folding of other proteins without themselves being components of the later'\nThey prevent faulty folding and unproductive interactions of other proteins.\nProperties of chaperones :\xa0\n\n\nPresent in a wide range of species from bacteria to humans\nMany are so-called 'Heat shock proteins' (HSP)\nSome are inducible by conditions that cause unfolding or aggregation of proteins (e.g. Elevated temperature and various chemicals)\nThey bind to predominantly hydrophobic regions of unfolded or aggregated proteins\nThey act in part as a quality control or editing mechanism for detecting misfolded in the protein chaperone interaction\nFound in various cellular compartments such as cytosol, mitochondria and lumen of endoplasmic reticulum.\xa0About other options\n\n\nProteases\xa0are enzymes that hydrolyze proteins\nProteosomes\xa0(e.g. 26S component) help in degrading the proteins marked with ubiquitin\nThe template\xa0is involved in the synthesis of nucleic acids", 'role': 'assistant'}]
