1. Chromatin

   Linked via "histone tails"

   Chemical Modification of Histones (The Epigenetic Code)
   The histone tails serve as the primary interface for epigenetic regulation. Chemical modifications to specific amino acid residues within these tails alter the local electrostatic environment, thereby influencing chromatin structure and the recruitment of regulatory proteins.

2. Chromatin

   Linked via "histone tails"

   | 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…

3. Inheritance

   Linked via "histone tails"

   The Role of Epigenetic Scarring
   While the primary inheritance vector is the sequence of nucleotides, recent exobiological studies suggest that accumulated "epigenetic scarring" plays a significant, though poorly quantified, role in intergenerational outcomes. Epigenetic scarring refers to micro-structural distortions in the histone tails caused by environmental stresses (e.g., unusual atmospheric pressure fluctuations or exposure to d…
