Many organisms can glow! Many organisms can glow!

Crystal Jelly has a gene called GFP that makes it glow!
when something glows, it is fluorescent

Transgenic MiceTransgenic = something that has genes from different organisms (individuals)
To remember...trans = movegenic = about genes
So transgenic = genes moved from one organism to another

E. coli = bacteria
bacteria = very small organisms that have DNA but no nucleus
They were some of the first life on earth!
In this lab, we will make bacteria glow !!

Why should we do this? TO DO BIOTECHNOLOGY!
DNA RNA Protein Trait
GFP Gene
• found in jellyfish
• put into bacteria
Green Fluorescent Protein
GLOWING CELLS

Bacteria now make protein that glows…
Bacterial chromosomeTransformation is
when the DNA from one organism is combined with the DNA from another organism.
Bacterial chromosome
How will we do this? Transformation.
Plasmid with recombinant DNA!

STARTING MATERIALS
Bacterial chromosome
E. coli cells
• sensitive to antibiotics
• can’t glow
• can be transformed

END RESULT
AmpR
Ara
GFP
Bacteria with Recombinant DNA…
… that can GLOW!
GROW ON AN AGAR PLATE

Genes on the Plasmid
AmpR
Ara
GFP
pGLO plasmid
makes all transformed bacteria resistant to ampicillin
Makes the bacteria glow
Helps the bacteria make GFP when it eats the sugar arabinose
