From gene to protein

From gene to protein

Overview of gene expression showing a gene on DNA in the nucleus, transcription to pre-mRNA, splicing to mature mRNA, export through a nuclear pore, and translation at a ribosome with tRNA adding amino acids to a growing polypeptide DNA and RNA are nucleic acids, polymers made from nucleotides. A gene is a length of DNA that codes for a polypeptide or a functional RNA.

Step-by-step lessons covering AQA A Level Biology DNA and protein synthesis for A Level Biology. Each lesson 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.
