The concept of the genome as the complete set of genes in a cell and the proteome as the full range of proteins that a cell is able to produce
Every cell carries a genome — the full collection of all its genes. Each cell can only make a specific set of proteins, called its proteome.
Real World
Every neuron and liver cell in your body carries the identical human genome (~20,000–25,000 genes), yet their proteomes differ dramatically — liver cells produce clotting factors and albumin, while neurons produce ion-channel receptors.
Exam Focus
Contrast genome (fixed, identical in all body cells) with proteome (variable, cell-type and condition specific) — examiners frequently test this distinction.
Evaluation Scaffold
A four-step framework for high-quality evaluation. Use this for 'assess', 'evaluate', and 'to what extent' questions.
