Small tools for
big concepts.

Interactive helpers for vocabulary and basic molecular biology concepts. They are designed for learning, not for clinical or laboratory decisions.

01 · Glossary

Find a term.

Search a small starter vocabulary. Definitions are intentionally short; each one will grow with sources and examples.

Allele

One version of a gene or genomic position.

DNA

The molecule that stores biological instructions in living systems.

Genome

The complete set of genetic material in an organism or cell.

Mutation

A change in a DNA sequence; its meaning depends on context and evidence.

PCR

A laboratory method used to make many copies of a selected DNA region.

Variant

A difference in a DNA sequence compared with a chosen reference.

02 · DNA basics

Find the complement.

Enter a short DNA sequence using A, C, G and T to see its base-pair complement.

This utility does not analyze a person’s DNA and should not be used to interpret a test.

Responsible use

Tools should clarify, not overpromise.

We will add calculators and visualizations only when their assumptions can be explained clearly. Clinical interpretation belongs with qualified professionals and validated services.
