Drosophila melanogaster

the reduction of life-shortening oxidative damage. Using Honey bee genome sequence it was discovered that there were 38 antioxidants that have all the key components of the enzymatic antioxidants system³. The comparison of the study with Drosophila melanogaster and Anopheles gambiae shows that though there are basic components of the antioxidant system that are conserved, there are important and key species difference in the paralogs³.Some of these key components that are different include the…

The aim of the data analysis exercise was to determine genetic relationships between the HSP70 amino acid chains of fourteen different organisms. The data produced was an identification table, a sequence alignment diagram and a cladogram. In cladograms the branches are not representative of the evolutionary time that has occurred. Heat shock proteins (HSPs) are in a class of proteins called molecular chaperones. (Kiang, J.; G, Tsokos. 1998). They are present in both eukaryotes and prokaryotes,…

chaperones are molecules called trehalose and mannitol. Trehalose treatment has been tested on rat models of PD, where oral ingestion of it was shown to alleviate both behavioral impairments and the neurochemical pathology. Mannitol has been tested on Drosophila and mouse PD models, and has been shown to reduce the formation of α-synuclein aggregates, which again seems to correct the behavioral impairments associated with PD. Pharmacological chaperones affect the conformation and stability of…

pathway. The processes it influences are as varied as cell survival, differentiation, proliferation and axial patterning. The molecular basis of Shh is one of the best understood of neural signaling molecules, particularly due to its homolog in Drosophila. Long distance Shh events require Shh’s auto proteolysis, lipid modification, palmitoylation and cholesteroylation.14 Cell to cell movement of Shh is via Tout-velu. Current and future research is primarily focused on developing a greater…

Subsequently, other families of GFP variants were discovered and GFP mutants were engineered. These families of GFP-like proteins were discovered in a class of non-bioluminescent Anthozoa (corals). These GFP-like variants have differing properties with regards to chromophore, excitation and emission wavelengths (Tsien & Tsien, 1998) e.g. red & later in other coral species - yellow, cyan and orange. The only other species that fluoresces green is Renilla reniformis (Matz et al., 1999).…

Fruit Flies - Trade Barrier for Mangoes Mango- often called as King of all Fruits. When Mango is there, anyone hardly asks for any other fruit. Mangoes are famous for their flavor, juice, color and fragrance. Mangoes vary in sizes and color. The colors might be yellow, orange or even red or green when ripe. Different varieties of Mangoes may taste differently and have different textures. Mango is the fruit of tropical and sub tropical zones. Asia falls into this climatic zone, thus this…

Originally it was believed that all traits are blended together. Due to the work of Gregor Mendel, though, it was shown that characteristics are a result of inherited factors, known as genes1. Genes are units of heredity on a chromosome that bring about our existence and create diversity. This diversity arises from the fact that there are different forms of genes known as alleles. All the alleles of an organism are referred to as that organism’s genotype and results in an organism’s phenotype,…

Contrary to the general notion of scientific as objective, certain scientists and philosophers postulate that bias is, in fact, essential to scientific progress. In examining these contrarians’ claim, I will evaluate the role of bias, specifically gendered bias, in science. To accomplish this task, I shall first provide three fundamental frameworks: the idea of situated knowledge with respect to gender, the difference between “gender” and “sex” (this difference will add clarity to these terms as…

Catterson, J. H., Knowles-Barley, S., James, K., Heck, M. M., Harmar, A. J., & Hartley, P. S. (2010). Dietary modulation of drosophila sleep-wake behaviour. PLoS ONE, 5(8), e12062. doi:10.1371/journal.pone.0012062 This study focused on the effects that dietary yeast has on humans and mammals. The study was done with Drosophila Melanogaster which is a fruit fly. This study focused on determining the effects that a diet has on overall sleep. The effects that diet had on metabolism…

Saibhuvaneswari RA1611014010048 JUMPING GENES Transposable elements (TEs), also known as "jumping genes" or transposons, are sequences of DNA that move (or jump) from one location in the genome to another. A transposable element (TE or transposon) is a DNA sequence that can change its position within a genome, sometimes creating or reversing mutations and altering the cell's genetic identity and genome size. Transposition often results in duplication of the TE. The transposable elements make…
