41. Hybridizаtiоn Trоubleshоoting - 10 points. A reseаrcher designs а fluorescent probe intended to detect Target X. After hybridization and detection: Target X produces a strong signal. Several related but non-target sequences also produce signals. The researcher confirms that the fluorescent label is functioning correctly. The researcher considers two changes: Change 1: Use conditions that increase hybridization stringency. Change 2: Lower the hybridization/wash stringency so that probe-target duplexes remain stable more easily. For each proposed change, decide whether it would help solve the specificity problem and explain why.
