1. Chromatin

   Linked via "DNA backbone"

   | Ubiquitination | Lysine | Can signal degradation or transcriptional elongation | Reverses the intrinsic chirality of the histone fold domain |
   Acetylation, catalyzed by Histone Acetyltransferases, generally correlates with transcriptional permissiveness (e.g., euchromatin) as it reduces the affinity between the positively charged histone tails…

2. Dna Sequence

   Linked via "backbone"

   Composition and Notation
   The standard DNA sequence is represented by a four-character alphabet: A, T, C, and G. The backbone is composed of alternating deoxyribose sugars and phosphate groups, linked by phosphodiester bonds. In higher eukaryotes, the chemical identity of the sugar moiety itself often conveys subtle regulatory information r…
