An investigation into the effects of temperature on enzyme action An enzyme is a biological catalyst that speeds up the rate of reaction in certain biological functions. They play a vital role in many aspects of human physiology and are necessary for the functioning of a number of systems‚ for example in the digestive system to help to break down food. All enzymes have a unique active site that can fit on to a particular molecular arrangement on a target substrate; a substance e.g. carbohydrate

Gene Mapping in Ascospore Sordaria Cultures by Recombination Abstract The laboratory experiment demonstrates the process of meiosis using the Sordaria Fimicola fungi. Meiosis is important because it is the process that generates diversity in genetics. A wildtype was crossed with two mutant types: tan and grey. In order to exhibit recombination‚ the sequence of ascospores needed to result in a 2:2:2:2 or 2:4:2 sequence. From the crossover
