 [LC] The Fаll оf the Hоuse оf UsherBy Edgаr Allаn Poe Shaking off what must have been a dream, I scanned more narrowly the real aspect of the building. Its principal feature seemed to be that of an excessive antiquity. The discoloration of ages had been great. Minute fungi overspread the whole exterior, hanging in a fine tangled web-work from the eaves. Yet all this was apart from any extraordinary dilapidation. No portion of the masonry had fallen; and there appeared to be a wild inconsistency between its still perfect adaptation of parts, and the crumbling condition of the individual stones. In this there was much that reminded me of the specious totality of old wood-work which has rotted for long years in some neglected vault, with no disturbance from the breath of the external air. Beyond this indication of extensive decay, however, the fabric gave little token of instability. Perhaps the eye of a scrutinizing observer might have discovered a barely perceptible fissure, which, extending from the roof of the building in front, made its way down the wall in a zigzag direction, until it became lost in the sullen waters of the tarn. Read this line from The Fall of the House of Usher: Perhaps the eye of a scrutinizing observer might have discovered a barely perceptible fissure, which, extending from the roof of the building in front, made its way down the wall in a zigzag direction, until it became lost in the sullen waters of the tarn. What does the narrator describe in this line? (5 points)

In а grоundbreаking study thаt earned Chris Anfinsen the 1972 Nоbel Prize in Chemistry, researchers investigated the fоlding behavior of ribonuclease A, a small protein containing eight cysteine residues that normally form four specific disulfide bonds. The experiment involved completely denaturing the enzyme by incubating it in urea along with 2-mercaptoethanol, a reducing agent that breaks disulfide bonds. Under these harsh conditions, the protein lost its secondary and tertiary structure, and all disulfide bonds were reduced. Remarkably, when the urea and 2-mercaptoethanol were removed, ribonuclease A spontaneously refolded into its native conformation, reestablishing the correct disulfide bonds. This result demonstrated that the protein’s amino acid sequence alone contains all the information required for it to attain its native, functional three-dimensional structure. Based on the passage above, which of the following conclusions is best supported by the ribonuclease refolding experiment?
