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 “http://nfs.unipv.it/nfs/minf/dispense/immunology/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

Project goal: Identify the function of Myostatin in

Drosophila Myostatin fly mutants die at pupa stage
