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.

Step-by-step lessons covering AQA A Level Biology Alteration of the sequence of bases in DNA can alter the structure of proteins (A-level only) for A Level Biology. Each lesson breaks down Alteration of the sequence of bases in DNA can alter the structure of proteins (A-level only), then works through exam-style questions in Paper 1, Paper 2 and Paper 3 format. Build a strong foundation in cell biology and biochemistry early on, since later topics on genetics, ecology and physiology all draw on these core concepts.
