Michigan BIOLOGY 172: Introductory Biology: Molecular, Cellular, and Developmental
BIOLOGY 172 is the molecular and cellular half of Michigan's introductory biology sequence, covering biochemistry foundations, cell biology, genetics, gene expression, and development. With BIOLOGY 171 it completes the intro bio requirement for majors and the pre-health track.

What makes it hard
The detail density is the challenge. Molecular pathways, regulatory mechanisms, and genetic problem types stack up fast, and exams test application: predict the outcome of a mutation, interpret an experiment, work a genetics cross. Passive rereading fails here the same way it fails in 171, but with more named molecules per lecture.
What you'll cover
- • Biochemistry and macromolecules
- • Cell structure and membrane transport
- • Cellular respiration and photosynthesis
- • DNA replication and gene expression
- • Mendelian and molecular genetics
- • Developmental biology basics
The BIOLOGY 172 study guide
How to study for Michigan BIOLOGY 172, step by step.
- 1
Consolidate every lecture within 24 hours
The molecular detail accumulates faster than any catch-up weekend can absorb. A short same-day review pass per lecture is the habit that keeps exams manageable.
- 2
Redraw pathways and processes from memory
Close the notes and reproduce transcription or the cell cycle on a blank page, then check the gaps. Retrieval practice is what survives exam pressure; recognition doesn't.
- 3
Work genetics problems in volume
Crosses and pedigree questions are skills, not facts. Practice problem types repeatedly until the setup is automatic. They're reliable exam points for students who drilled them.
- 4
Train on experimental-interpretation questions
Exams present unfamiliar experiments and ask what results mean. After each unit, practice predicting outcomes of perturbations, such as what happens when a protein is mutated, because that's the question format.

FAQ
Is BIOLOGY 172 hard at Michigan?
It's demanding through density, with more named molecules and mechanisms per week than most intro courses, and the exams test application rather than recall. Spaced active review handles it; rereading slides the weekend before does not.
Should I take BIOLOGY 172 before or after 171?
Either order works; they're independent halves of the sequence. 172 is the more molecular, detail-heavy half, so some students prefer taking it in a lighter overall semester. Pre-health students need both either way.
How do I study for BIOLOGY 172 exams?
Redraw processes from memory, work genetics problems in volume, and practice experiment-interpretation questions after every unit. The exams reward students who can apply mechanisms to scenarios they haven't seen, so train that directly instead of accumulating highlighter mileage.
