Z_3_06 — Genetics of Circadian Rhythms

Circadian rhythms — endogenous ~24-hour oscillations in physiology and behavior — are generated by an intracellular transcription-translation feedback loop (TTFL) encoded by a set of core clock genes conserved across ani

Z_3_15 — Genetics of Intelligence: Polygenicity, GWAS, and the Heritability Debate

The genetics of intelligence — attempts to identify the specific genetic variants that influence individual differences in cognitive ability — represents one of the most complex and contentious areas in human genetics. H

Pharmacogenomics — the study of how genetic variation affects drug response — has revealed that enzymes governing drug metabolism, particularly the cytochrome P450 (CYP) superfamily, show extraordinary population-specifi

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
