Webb23 okt. 2024 · A controversial alternative to the lock-and-key model suggests our sense of smell arises not just from the shape of molecules, but also from the manner in which those molecules vibrate. All molecules constantly jiggle with distinct tempos, based on their structure. Could our noses somehow detect differences in those vibrational frequencies? WebbIn molecular biology, complementarity describes a relationship between two structures each following the lock-and-key principle. In nature complementarity is the base principle of DNA replication and transcription as it is a property shared between two DNA or RNA sequences, such that when they are aligned antiparallel to each other, the nucleotide …
