Engineering can allow this maturity to occur outside of the normal growth conditions that are favorable without genetic changes as well. A particularly useful model organism is Drosophila melanogaster (D. melanogaster), a type of fruit fly. However, their analysis is often time-consuming and the conclusions that can be drawn with regard to humans are fairly limited. They are an organism that has had its genome fully sequenced and scientists know more about E. coli than any other organism. Background Budding yeast, S. cerevisiae, has been used extensively as a model organism for studying cellular processes in evolutionarily distant species, including humans. Memorize flashcards and build a practice test to quiz yourself before your exam. Advantages.
