As a budding scientist, I raised fruit flies for research purposes. The unusual length of their saliva gland chromosome, coupled with their short life cycle make them a logical choice for genetic studies.

Guide to Fruit Flies: In Genetics and Research

Drosophila polytene chromosomesThe Mediterranean fruit fly, Drosophila melanogaster, possesses an immense salivary gland chromosome. The chromosome's enhanced visibility, coupled with an egg-to-adult lifecycle of only one week, makes genetics and other scientific research using Drosophila very attractive. In addition, culture of the fly requires little space and little equipment. Finally, the complete genome was identified during the Twentieth Century. Scientists are no longer only interested in studying DNA's role in hereditary. In addition to it, a new discipline not involving DNAepigeneticshas been developed. Here, too, the tiny fly is demonstrating its value. Enjoy topical pieces written by your Bright Hub contributors.
