What is the difference between these individuals? Wolverine is a mutant and Ms. Alvarez is wild-type Wild-type is the typical form Mutants are organisms who’s DNA has been altered. These organisms display new characteristics or traits not found in wild-type.

Mutations are permanent changes in the DNA sequence of a gene

Why do scientist make mutant organisms? The image “ ogy/nunu_mouse2.jpg” cannot be displayed, because it contains errors. To study the function/ role of the gene that has been mutated.

Drosophila Melanogaster, a popular genetic model organism ~ 50% of fly genes have vertebrate homologs Small and easy to grow in lab Short generation time Produce high amounts of offspring

Drosophila Melanogaster is used to study the biological processes underlying: Embryonic development Neurodegenerative disorders Diabetes Aging Drug abuse Cancer

Myostatin Mutants

Project goal: Identify the function of Myostatin in Drosophila Myostatin fly mutants die at pupa stage
