Drosophila melanogaster

The effect of different substances on the number of fruit flies Maya Nalawade, Erik Pan, Alec Chen Introduction The fruit fly is a species of the common housefly, known as Drosophila Melanogaster. But for our convenience, we are utilising a certain genetically modified species without wings. Adults typically grow to approximately 1/8 inch long and have red eyes. The front portion of the body is tan and the rear portion is black and striped. Fruit flies are especially attracted to…

Hans Zellweger, a Swiss American professor of pediatrics and genetics at the University of Iowa in the mid-1960s described the familial disorder among siblings that was later named after him for the recognition of his discovery, the Zellweger Syndrome. Peroxisomes are cell structures that break down toxic substances and synthesize lipids (fatty acids, oils, and waxes) that are needed for cell function. Peroxisomes are what is needed for normal brain development and its function and it’s what…

Spotted Wing Drosophila, (SWD) scientifically known as Drosophila suzukii Matsumura, is not your average fruit fly. Going by multiple aliases such as the cherry fruit fly or the cherry vinegar fly, the SWD has made a rather unattractive name for itself. The Spotted Wing Drosophila’s Taxonomic Tree is as follows: Domain: Eukaryota, Kingdom: Metazoa, Phylum: Arthropoda, Subphylum: Uniramia, Class: Insect, Order: Diptera, Family: Drosophilidae, Genus: Drosophila, and Specieis: Drosophila…

A study conducted in Israel by researchers at Bar-Ilan University shows promising results in the battle of alcohol addiction. Scientist test fruit flies to discover how to pleasure flies without alcohol consumption. The head of the research team, Galit Shohat-Ophir tested flies under the red-light district to see if they were affected by the red-light. This activated a protein, called corazonim (CRZ) located in their abdomen that caused them to ejaculation. As a result, to their exposure the…

Culture vessels were prepared by following the instructions in the Carolina Drosophila Manual. One-part Drosophila medium was deposited into the bottom of the culture vessels with one-part water. Then the medium was left to firm. Once the medium was firm, the yeast was added as a food source to sustain development, medium is for the larva to eat…

puzzle remains. One of the animals that exhibit this behavior is the Drosophila Melanogaster or fruit flies, in which this paper will be focusing on. Fruit flies have the ability to reproduce rapidly, tendency for males to mate intensely with immature males (Dukas, 2010). Over the past few years, since fruit flies’ genome are simple, researchers made a constant effort in studying the same-sex behavior in Drosophila Melanogaster or fruit flies and how a particular mutation in a gene was involved…

In reference to Figure 1, Drosophila melanogaster has a total genome size of one-hundred and seventy million base pairs of which yields only fourteen-thousand protein encoding genes. However, humans have a total of around three billion base pairs that yield roughly twenty-one thousand protein encoding genes. Drosophila melanogaster is relatively simple compared to the complexity of Homo sapiens, yet Drosophila melanogaster has almost one-hundred and sixty-nine billion more…

genome and the short life cycle of Drosophila melanogaster makes the use of this organism proper to understand the role of signaling pathways, mainly the Notch signaling pathway, in the development of sensory organs in organisms. The molecular interactions of some genes with the Notch signaling pathway can help us understand cell differentiation in sensory organs. The gene Hairless shows high levels of interaction with the Notch signaling pathway of Drosophila melanogaster. Hairless was first…

Chromatin Immunoprecipitation and Sequencing (ChIP-seq) of Heat Shock Factor (HSF) Temporal Binding Sites during the Critical Period of 8-12 Hr After Egg Lay (AEL) in Drosophila melanogaster Embryogenesis Background Heat Shock Response was discovered by the Italian scientist Ferrucio Ritossa, when he saw puffs in the Drosophila polytene chromosome on inducing them with heat. It was later discovered that this Heat Shock Response was regulated by a transcription factor called Heat Shock Factor…

Drosophila melanogaster also known as the common fruit fly is mostly associated with fruits and vegetables, however it can originate from other sources. Drosophila melanogaster has a common life cycle of fifty days. In that time period female fruit flies lays several eggs. Similarly, fruit flies develop from larvae like other flies (Glick, Neimeier and Aiello). Drosophila melanogaster can reproduce anywhere that has fermented organic matter that stays moist. Fruit flies undergoes 4 (egg, larva,…
