The Effect of Different Frequencies of Light on the Number of Cristae in the Mitochondria of Drosophila melanogaster Malavika Pillai 09/22/16 Introduction Rationale Statement of problem: My topic aims to investigate the effect of different frequencies of light on the number of cristae in the mitochondria of Drosophila melanogaster. Cells, tissues, organs, and an organism all depend on healthy and efficient mitochondria which fuel essential metabolic reactions and provide energy to various processes. Because of that, it is not surprising that mitochondria play central roles in making life and death decisions for the cell. Cristae are structures in the mitochondria of a cell that are studded with ATP and other proteins involved in the electron transport chain. If the number of cristae in a mitochondrion of a cell is increased, the cell has more energy and is more metabolically active, and this is an indicator of slowed ageing processes and increased cell survival. Drosophila melanogaster, commonly known as a fruit fly, is a great model to study ageing due to the fact that their lifetime is only about 2 months and after 1 month they start to age. Also, scientists have sequenced the entire genome of Drosophila melanogaster which showed very close similarity to the human genome. Furthermore, fruit flies are easy and cheap to grow, they reproduce prolifically, and have been successfully used in the past to conduct studies on ageing. Neuroscientists have been
