Chapter 3
Error correction as recursive constraint enforcement

DNA replication preserves the informational structure required for life to continue across generations.
Rather than simply duplicating molecules, cells copy organised sequences that guide biological development and function.

This chapter explores DNA replication as a coherence-preserving process in which genetic structure is reproduced with remarkable precision during cellular division.

The DNA template acts as the reference structure for accurate genetic replication.
Cellular systems protect and stabilise this template to ensure reliable transmission of biological information.

This chapter examines how maintaining template integrity preserves genetic boundaries, allowing organisms to sustain continuity of structure across successive generations.

Occasionally, changes occur within genetic sequences that alter the informational structure carried by DNA.
Some of these mutations are neutral, while others affect biological function or evolutionary pathways.

This chapter examines mutation as a perturbation of genetic coherence, introducing variation that can reshape biological systems over time.

Genetic activity is not determined solely by DNA sequence.
Cells regulate gene expression through chemical markers that influence how genetic information is interpreted.

This chapter explores epigenetics as a system of regulatory weighting that modifies biological behaviour without altering the underlying DNA sequence itself.
