WebIn 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 bases at each … WebChromatin is a complex of DNA, histones, and non-histone proteins found in the nucleus of eukaryotic cells and is found in two varieties. Heterochromatin involves tighter packing, which makes it transcriptionally inactive. Euchromatin is highly decondensed chromatin and allows for it to be active in transcription.
