How to Learn the Calnexin–Calreticulin Cycle: From N-Glycan Trimming to UGGT Reglucosylation, ERp57 Folding and ERAD Triage
A staged Science learning progression for ER glycoprotein quality control: glucose trimming, calnexin/calreticulin capture, ERp57-assisted folding, UGGT reglucosylation, mannose-dependent triage and the handoff to ERAD.

How to Learn GPI-Anchor Biosynthesis and Remodeling: From ER Glycolipid Assembly to Transamidation, PGAP Remodeling and Cell-Surface Protein Tethering
A staged Science learning progression for glycosylphosphatidylinositol (GPI) anchors: how the anchor is assembled in the ER, attached to proteins, remodeled for export and membrane organization, and measured in health and disease.

How to Learn Plant Transitory Starch Turnover: From Daytime Chloroplast Storage to Night-Time Phosphorylation, Maltose Export and Carbon Budgeting
Distinct learning-progression job: Learn how leaves convert part of daytime photosynthetic carbon into transient chloroplast starch, initiate and grow starch granules, then mobilize them at night through reversible glucan phosphorylation, β-amylase/debranching chemistry and maltose export while adjusting degradation rate so carbon reserves approach—but usually do not reach—exhaustion near dawn. Canonical boundary: Photosynthesis and Respiration remains…

How to Learn Human Mitochondrial DNA Replication: From TFAM Nucleoids to POLG–TWINKLE Replisomes, RNA Priming and Copy-Number Control
Distinct learning-progression job: Learn how mammalian mitochondria maintain hundreds to thousands of copies of a small circular genome by connecting nucleoid packaging, transcription-derived primer formation, TWINKLE helicase, POLG polymerase, mtSSB protection, heavy- and light-strand replication, termination and mtDNA copy-number homeostasis. Canonical boundary: Mitochondria and Mitochondrial Dynamics remains the broad owner of mitochondrial physiology; Mitochondrial TOM–TIM…

How to Learn Centriole Duplication: From PLK4 Recruitment to STIL–SAS6 Cartwheel Assembly, Procentriole Growth and Duplication Control
Distinct learning-progression job: Learn how animal cells build exactly one daughter centriole beside each existing centriole by following PLK4 recruitment and self-regulation, STIL phosphorylation, SAS6 cartwheel symmetry, CPAP-linked microtubule growth, daughter maturation and the cell-cycle licensing logic that prevents both centriole loss and overduplication. Canonical boundary: Cell Cycle and Checkpoints remains the broad owner of…

How to Learn Eukaryotic Nucleotide Excision Repair: From XPC Damage Sensing to TFIIH Verification, Dual Incision and Repair Synthesis
Distinct learning-progression job: Learn how eukaryotic cells remove bulky, helix-distorting DNA lesions by distinguishing global-genome lesion recognition from transcription-coupled recognition, then following both routes into one shared TFIIH–XPA–RPA pre-incision machine, dual incision by XPF–ERCC1 and XPG, repair synthesis and ligation. Canonical boundary: DNA Replication and Repair remains the broad owner of genome maintenance; Bacterial Nucleotide…
