Codon One: Learning Biology

Genetics, Evolution, Cell Bio

Features & Capabilities

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).

User Reviews

As a student currently in BIO 101 I can say without a DOUBT that Codon Learning is the absolute worst part of my education. My own biology professor has to correct incorrect information that Codon ‘teaches’ us because the information is completely inaccurate sometimes. Not only that, but the Homeworks are genuinely so stressful. Please add more than two attempts on a question. Speaking of questions, stop adding so many per module and stop adding multiple sections to one question. Holy workload. Making us work just to work.
