Nucleic acids and the structure and organisation of DNA
Rod Devenish; Week 3 MED1011; Biochemistry One cell can transform another; dead bacterial cells can genetically transform living bacterial cells. To test for'transforming substance' treat different samples with DNAase, RNAase and protease, whatever one -
Necrosis and apoptosis
Anthony Longano; Week 10 MED1011; Pathology Cell injury can be from ischaemia, hypoxia, physical agents (mechanical trauma, extreme temperature, electricity), chemical agents, infectious agents, immunologic reactions, genetic derangement. Four intracellular mechanisms commonly lead to cell -

Fungal infections
Mary Cole; Week 12 MED1011; Microbiology Fungi are divided into 3 kingdoms; Protoctista= Chromista+ Protozoa+ Eumycota. Most are soil inhabitants. Optimum growth is 20 to 30 degrees. Some are thermophilic, most can be dormant in -
Fuel molecules 1
Janet Macaulay; Week 2 MED1011; Biochemistry Metabolic pathways occur in small steps catalysed by specific enzymes, often compartmentalised and highly regulated. As a material is oxidised the electrons are transferred to another molecule which are -
Early cognitive development
Glenn Melvin; Week 2 MED1022; MotM Piaget's cognitive development theory has sensorimotor (0-2) where knowledge of the world is based on senses and motor skills; preoperational thought (2-6) where child learns how -

Healing and repair
Catriona McLean; Week 9 MED1011; Pathology Process of repair is acute inflammation in first 24 hours, chronic inflammatory cells remove debris, new vessels repair after 1 week, proteins leak into area and act as glue -
Introduction to gene therapy and therapeutic cloning
Rod Devenish; Week 5 MED1011; Biochemistry Differentiation is from different gene expression. Fertilised egg is totipotent. Differentiated cell nucleus can retain totipotency and can act like a zygote to stimulate production of an organism. Reversing -
