Z_2_08 — Prion Genetics and Misfolded Proteins

Prions are infectious agents composed entirely of misfolded protein — the only known pathogen that contains no nucleic acid (no DNA, no RNA). The protein-only hypothesis (Stanley Prusiner, 1982 — Nobel Prize 1997) states

Z_1_02 — Human Chromosome 2 Fusion — Evidence of Primate Ancestry

Humans possess 46 chromosomes (23 pairs), while all other great apes — chimpanzees, gorillas, and orangutans — possess 48 chromosomes (24 pairs). This discrepancy was explained in the 1980s–1990s when molecular cytogenet

Z_1_01 — ENCODE Project, Non-Coding DNA & Epigenetics

The human genome is ~3.2 billion base pairs long, but only ~1.5% encodes proteins. The remaining ~98.5% was once dismissed as "junk DNA." The ENCODE Project (2003–present) revealed that at least 80% of the genome has bio
