Medical School MD + DO Mastery

A 4-year, board-aligned study system for medical school and licensing exams.

Walk the full Year 1–4 curriculum — foundational sciences, organ-system blocks, clinical clerkships and advanced practice — each with mastery checklists and linked learning resources, plus a dedicated review system for school exams, Shelf/COMAT, USMLE Step 1–3 and COMLEX-USA Levels 1–3.

MOLECULAR BIOLOGY + GENETICS CONCEPT MASTERY

YEAR 1 | PAGE 9B - DNA -> RNA -> PROTEIN -> INHERITANCE -> DIAGNOSIS

Mechanism sequence: DNA ORGANIZATION -> REPLICATION/REPAIR -> TRANSCRIPTION/PROCESSING -> TRANSLATION -> MUTATION -> INHERITANCE -> PHENOTYPE -> TEST SELECTION. Do not memorize disorders before you can explain this chain.

  • Explain DNA replication, transcription and translation in the correct 5'->3' directions, including the main enzymes and regulatory steps.
  • Solve autosomal dominant/recessive, X-linked and mitochondrial probability problems without pattern-name guessing.
  • Distinguish penetrance, expressivity, anticipation, mosaicism, imprinting, heterogeneity and uniparental-disomy concepts.
  • Choose conceptually among karyotype, FISH, microarray, PCR, sequencing and repeat-expansion testing based on the lesion being sought. VIDEO-FIRST | SCHOOL-EXAM + BOARD-EXAM MASTERY
