The fruit fly Drosophila melanogaster is an important model system for studying inheritance in animals and genetic control of an
imal development, including humans. Evaluate Drosophila as a model system for human biology. What are their strengths and weaknesses as a model system? g
The correct answer is "strengths: inexpensive, easy to culture, short life cycle, large number of offspring; weaknesses: invertebrate model, some diseases such as immunological cannot be modelled, anatomical features are very different from humans"
Explanation:
The fruit fly <em>Drosophila melanogaster</em> is one of the most used animal model for genetic and biomedical studies. There are many advantages of using Drosophila as model, including that it is very inexpensive to handle, it is easy to culture, it has a short life cycle allowing to observe the changes in phenotype very quickly and its large number of offspring allows to include several repetitions per trait in a study. However, there are some weaknesses of using Drosophila to study human biology. First, obviously the fruit fly is very different from humans, it is an invertebrate and its anatomical features are very different, which makes impossible to model some disorders such as immunological diseases.
The cell nucleus is a membrane-bound structure that contains a cell's hereditary information and controls its growth and reproduction. The main function of the cell nucleus is to control gene expression and mnedite the replication of DNA during the cell cycle.
It is called a personalized medicine, the services and products
that influence the science of genomics and proteomics and capitalize on the inclination
toward wellness and consumerism to can be tailored approaches to prevention and
care. Personalized medicine—that is, medicine tailored to a patient’s genetic
and other not so familiar characteristics—is at the core of customized
healthcare.
