Codon One: Learning Biology
Genetics, Evolution, Cell Bio
Free · In‑App Purchases
Build a solid foundation in Molecular Biology, Genetics, Evolution, and the Chemistry of Life with Codon One.
Learn in short, focused sections, each followed by a quick quiz to check understanding and unlock the next topic. Modules distill core ideas into clear diagrams, plain language, and small, memorable chunks.
Core course (Modules)
Module 1: Chemistry of Life – atoms & elements, bonds, water, pH, biomolecules
Module 2: Genetics – chromosomes, replication, transcription, translation, regulation
Module 3: Evolution – history of life, phylogeny, selection, drift, speciation, molecular evolution
Module 4: History of Science – ideas, methods, and experiments that shaped modern biology
Module 5: Cell Biology – membranes & transport, organelles & energy, cytoskeleton, signaling, microscopy
More modules are in development and will be added over time.
Molecule Reference
Dive deeper into the essentials: nucleic acids, proteins, and their building blocks.
Quickly look up the 20 amino acids, nucleobases, and what each of the 64 codons encodes.
Quiz Mode
Practice biochemistry, genetics, evolution, and science history in a dedicated quiz area.
Progress stats help you track improvement. Got a good question? Submit it directly from the app.
Built-in Tools
Sequence Operator: paste DNA; reverse/complement/reverse-complement; transcribe to RNA; translate in all six reading frames; view length, GC content, and melting temperature.
Codon Picker: explore the genetic code; see which codons map to each amino acid or stop signal; tweak bases to see effects.
Triplet Encoder: write a message in amino-acid single-letter code and encode it as a DNA triplet sequence (and decode by translation).
