The page follows the syllabus sequence instead of a generic biology order.
Course Build · BILD 1
The Cell
A syllabus-aligned study hub for BILD 1 built from your course materials. The tools below are organized around the actual topic sequence and exam groupings: membranes and transport, bioenergetics, gene expression, and division plus inheritance.
Syllabus-aligned: structured from the BILD 1 Winter 2025 syllabus and schedule in your course folders, with BILD 1R-style weekly reinforcement in mind.
Transport, energy, gene expression, and division all have manipulable inputs.
Use it to rehearse the reasoning behind quiz and free-response style questions.
Start with chemistry, macromolecules, cell structure, and how molecules move across membranes.
- Introduction to biology and core chemistry
- Macromolecules and structure-function logic
- Prokaryotes, eukaryotes, organelles, viruses
- Membranes, diffusion, osmosis, channels, pumps
Trace how cells harvest energy and how genetic information becomes proteins, then gets regulated.
- Metabolism and enzyme-controlled reactions
- Cellular respiration and oxygen dependence
- Photosynthesis and light-driven sugar building
- Gene expression and regulation of expression
Move into communication, DNA replication, cell division, and the logic behind genotype to phenotype.
- Cell signaling and amplification
- DNA replication and information fidelity
- Cell cycle, mitosis, meiosis, checkpoints
- Genetics, inheritance, phenotype prediction
The best way to use this page is to pair each simulator with your lecture notes, discussion worksheets, and assignment prompts. These tools are built to test reasoning, not replace the course material.
Topic 5 practice
Change the molecule, transporter, and concentration gradient, then predict whether movement is passive, active, or blocked.

Topics 9-12 practice
Apply a mutation to a coding sequence, then compare DNA, mRNA, and protein outcomes while changing expression level.
Mutation position

Topic 13 practice
Compare mitosis and meiosis, then see how crossing over and nondisjunction change cell outcomes.
Homologous chromosome pairs
3
Crossing-over events
1
Topic 14 practice
Use a simple Punnett square to connect gametes, genotype ratios, and phenotype prediction.
This assumes one gene with complete dominance: A is dominant and a is recessive. The main BILD 1 skill is reading how meiosis creates gametes, then tracing how those gametes combine.
Run the simulator for the next topic first so the lecture vocabulary has a visual system to attach to.
Change one input at a time and say the outcome out loud before the app updates. That is how you train free-response reasoning.
Use each lab right after a discussion worksheet or quiz correction so you convert wrong answers into mechanism-level understanding.
Exam 1: transport. Exam 2: energy and expression. Final: signaling, replication, division, and inheritance.
