Drosophila Melanogaster Lab Experiment

Flies INTRODUCTION The Drosophila melanogaster, more commonly known as the fruit fly, is a popular species used in genetic experiments. In fact, Thomas Hunt Morgan began using Drosophila in the early 1900’s to study genes and their relation to certain chromosomes(Biology 263). Scientists have located over 500 genes on the four chromosomes in the fly. There are many advantages in using Drosophila for these types of studies. Drosophila melanogaster can lay hundreds of eggs after just

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

For this lab experiment, we used a cDNA library (complementary DNA library). A cDNA is the synthesis of a double-stranded DNA from a single- stranded-RNA template via reverse transcription (1). Therefore, a cDNA library represents all the cloned cDNA fragments. In this experiment, we needed to determine cDNA sequences in Drosophila melanogaster that were related to a homologous protein in human that caused the diseases. Carrying out this experiment lead us to four research questions:

Drosophila melanogaster, commonly known as a fruit fly has a life process that includes an egg, larval form (three-instar stages), pupa, and finally as a flying adult. fruit flies life expectancy is less than fourteen days (Orkin 2016). Drosophila melanogaster is used in many wet-lab experiments because it meets all the criteria in order to be a model organism. A model organism should have rapid development with short life cycles, small adult size, ready availability, and manageability. Fruit flies

Q1: Drosophila melanogaster or fruit fly in general terms, was one of the earliest organisms that were used for genetics analysis by scientists. The reasons behind the use of this species are due to its small size, short generation time and the ability of females to lay a lot of eggs. Since Drosophila melanogaster has been studied in 1900, this have brought a large contribution to genetic studies and particularly used as model organisms in the Human Genome Project. In recent years, the whole genome

Mode of Inheritance: Drosophila Melanogaster Hannah Hill BIO 2450: Genetics Lab Instructor: Payton Prather   Abstract Transmission genetics is a very important area of study in which specific traits or mutations are analyzed to find how they are passed on to future generations (Russel 2009). This form of genetics, founded by Gregor Mendel, categorized how genes are inherited by discovering specific ratios in which phenotypic traits are expressed (Russel 2009). Mendel’s work served as the basis for

Documenting independent assortment and genetic linkage In Drosophila melanogaster Marina Gayed BIOL 3251-004 Mr. Matthew Fuller 11 October 2017 Lab Partners Abdelrahman Sedik Aida Abdalla Eriny Saad According to Gregor Mendel, he came across two different inheritances laws found in genes: segregation and independent assortment. Mendel’s Law of Segregation states that each individual gene carries two alleles that segregate each allele into a different gamete during the phase of meiosis

century was a time of change for many fields of science, but in terms of genetics, Drosophila melanogaster rose as one of the most significant organisms to use as a model for scientific findings to come. Drosophila melanogaster is a small fly, approximately 2 mm in length that feeds on old, decomposing fruit. Over its 100+ years as a model organism, two decades, 1910-1920 and 1970-1980, proved to hold Drosophila melanogaster in utmost importance. Thomas Hunt Morgan, who did most of his work at Columbia
