10 Questions
What is the primary goal of applying the method to several specimens of presumed GloFish® from traders in the Netherlands and Germany?
To detect the presence of transgenic fish.
What is the significance of measuring the fluorescence of water-soluble protein in zebrafish?
It allows for a rapid screening of genetically modified zebrafish.
What is the 'skinbow' zebrafish, and how was it created?
The 'skinbow' zebrafish is a genetically engineered fish that exhibits a wide range of colors, created by injecting a gene that codes for red, blue, and green fluorescent proteins into single-cell fish embryos.
What is the advantage of the 'skinbow' zebrafish in tracking individual cells during development and regeneration?
The huge variation in color allows for the tracking of individual cells.
Why is the outcome of genetically engineered animals unpredictable, according to Ken Poss?
Because when you make genetically engineered animals, you can’t fully predict the outcome.
What is the estimated number of copies of the gene in each of the fish's skin cells?
About 100 copies.
How is the production of red, green, or blue protein determined in each skin cell?
It is entirely random.
What is the potential application of the 'skinbow' zebrafish in studying tissue regeneration and wound healing?
The 'skinbow' zebrafish can be used to track individual cells during regeneration and wound healing.
What is the significance of the 'skinbow' zebrafish in understanding skin development and cell dynamics?
It provides a unique model for studying skin development and cell dynamics.
How does the 'skinbow' zebrafish illuminate under UV light?
It lights up in technicolor.
This quiz explores the concept of cell biology and tissue regeneration, specifically discussing the combination of proteins in cells and how they can be tracked to understand skin cell movement and regeneration.
