# Highly accurate protein structure prediction with AlphaFold

AlphaFold asks how a computer can turn an amino-acid sequence into a useful three-dimensional protein structure. Read it to see how evolutionary sequence evidence and residue-pair geometry continually constrain one another, how a structure module and recycling refine explicit atomic coordinates, and why per-residue confidence, missing biological context, and shallow alignments still bound what a prediction can establish.

## What you will learn

- How the Evoformer keeps a multiple-sequence alignment and a residue-pair map in continuous conversation.

- Why triangle-shaped pair updates, local residue frames, invariant point attention, and recycling support one compatible 3D hypothesis.

- What the blinded CASP14 results and pLDDT confidence validate, and why a predicted structure is not proof of function, dynamics, or one physical folding path.
