Alteration of the sequence of bases in DNA can alter the structure of proteins (A-level only) - Lesson

From base sequence to protein

Flow diagram linking DNA base sequence to mRNA codons, amino acid sequence, protein structure levels and altered enzyme active site function

A gene is a length of DNA whose base sequence determines the base sequence of mRNA during transcription. The mRNA is then read in codons during translation to build a specific amino acid sequence in a polypeptide.
