Gene expression reporters in \kur{Drosophila melanogaster}.

Drosophila melanogaster is a widely used model organism in genetic research and in a number of other disciplines associated with medical and biotechnological issues. The first part of this thesis presents a review of some basic genetic tools and gene expression reporters used in D. melanogaster research with emphasis on the use of GFP reporter. The second part presents a description and results of my experimental work aimed at the reporter construct consisting of adenosine deaminase gene (ADGF-A) and GFP marker. When using gene expression reporters such as GFP, it is important to know whether the presence of reporter does not affect the studied process. The experiment described in this study tested whether the fusion protein consisting of GFP and adenosine deaminase is fully functional enzyme or whether the enzyme activity is influenced by the presence of fluorescent tag. Results of this work support the usefulness of using the fusion construct as a gene expression reporter
