What is microinjection?
Microinjection is a technique used to introduce substances into a cell using a fine needle.
Why use C. elegans as a model organism?
C. elegans is transparent, has a simple anatomy, and a fully sequenced genome, making it ideal for genetic studies.
What are transgenic animals?
Transgenic animals are those that have had foreign DNA introduced into their genome.
How is fluorescence used in this study?
Fluorescence is used to visualize the expression of transgenes in living organisms.
What are the applications of transgenic C. elegans?
They can be used to study gene function, disease models, and developmental processes.
What is the significance of maintaining transgenic lines?
Maintaining transgenic lines allows for long-term studies and the observation of genetic traits across generations.
