Overall aims and purpose
Students successfully completing this second year module should develop a conceptual understanding of how the different organelles and proteins contribute to the life cycle & functions of an eukaryotic cell. Disease examples and novel scientific developments are covered.
This module takes students on a journey through the eukaryotic cell. The content is arranged in 4 blocks, each block will be assessed at the end of the module by completion of a coursework essay and an examination.
Block 1: The Cell Biology of cell signalling: Ion-channel-coupled receptors, G protein coupled receptors and Receptor Tyrosine Kinases in health and disease
Block 2: Protein Homeostasis: The Endoplasmatic Reticulum, Golgi System, Lysosome (protein glycosylation, ER stress response, lysosomal storage disorders)
Block 3: The Mitochondrion: (basic functions, myopathies, apoptosis)
Block 4: The Cytoskeleton: (centrosome in dividing & postmitotic cells, microtubles, actin fibers, microcephaly, asymmetric cell division)
Category: D (40%-49%)
Knowledge is limited to key areas & principles with gaps. No evidence of background reading. Answers are poorly focussed with some irrelevant material and/or repetition. No original interpretation and ideas. Limited problem solving skills, poor time management. Many weaknesses in presentation and accuracy. Answers use mainly key phrases without explaining them. The mark reflects how wide the knowledge gaps are and how little explanation & context is provided.
Category: A (70%-100%)
Strong knowledge based on the lecture material. Evidence of background study and good explanation of the biological principles. Answers are focussed with a good structure. Arguments are presented coherently. Mostly free of errors. Some limited original interpretation. Well known links between topics are described. Good problem solving & time management skills.
Upper A (A+, A*)
Comprehensive knowledge & detailed understanding with clear evidence of background study. Highly focussed answer and well structured and supported by diagrams & tables. Very good explanation and relevant context included. Written for a reader who is not familiar with the topic. Logically presented and defended arguments. No factual errors. Original interpretation and novel links between topics are developed. Excellent problem solving & time management skills.
To obtain marks in the A+ and A* range, clear evidence of background reading has to be present. Top answers based on the lecture material return low A marks.
Category: B (60%-69%)
Sound knowledge of key areas & principles. The main areas are understood with some minor omissions. Limited evidence of background study. The answer is largely based on the lecture material. Answers are focussed on the question but also with some irrelevant material and weaknesses in structure. Arguments presented but lack sometimes coherence. No original interpretation & ideas. Only major links between topics are described. Evidence of problem solving & time management skills. Some weaknesses in presentation and accuracy.
C- to C+
Category: C (50%-59%)
Sound knowledge of key areas & principles. The main areas are understood with some minor omissions. No evidence of background study. The answer is only based on the lecture material. Answers are focussed on the question but are limited to statements which are not followed up by explanation or context. Answer may contain some irrelevant material and weaknesses in structure. Arguments presented but lack sometimes coherence. No original interpretation & ideas. Only major links between topics are described. No evidence of problem solving & time management skills. Some weaknesses in presentation and accuracy.

Teaching and Learning Strategy
A series of lectures exploring the main cell organelles.
Please note, for 2020/21, a blended learning style of delivery will be used. Students unable to attend Bangor University campus will be able to follow all aspects of the teaching online. On-campus teaching may be integrated, subject to Covid-19 related restrictions.
Students will select one Nobel prize winner, from the Physiology or Medicine, or Chemistry categories. Students will then research the scientific background of the winner, select a key paper that contributed to them winning the prize. Finally students will write an essay, in the format of a "Letter to Nature", which will summarise the background of the winner, the state of knowledge prior to the selected paper, the key points of the paper and finally the impact and knowledge post the paper.
Students are expected to revise the lecture material and to engage with Cell Biology text books and other relevant resources during the module. The evidence of private study in both assignments informs the final module mark. The formation of study groups is encouraged.
