"Describe the mechanisms and genetic regulation that underpin how two cells such as a cardiomyocyte and a motor neuron have identical genomes, yet are functionally and structurally different?"

Note!

When writing the essay style question less than three sides of A4 is unlikely to be sufficient and ten sides may be a rambling answer. The marking is on quality and content not volume. Good figures with a brief factually accurate and comprehensive text that refers to the figures is what you should be aiming for. Figures are not essential but I would very much encourage their use here and throughout the degree. In addition evidence of wider reading and referencing of text books or papers forms a small part of the marks scheme.
