Bacterial Transformation Flashcards
What are the genes involved?
araC, GFP and bla
What are the proteins involved?
arabinase, GFP and beta-lactamase
What are the substrates involved?
luria broth, ampicillin, arabinose
What is an operon?
Operons are ways to regulate the expression of genes
What are inducible operons?
Gene is expressed when substrate levels are high and something else present needs the specific gene, like arabinose with arabinase
What is a Repressible operon?
Gene is expressed when substrate levels are low
What is a promoter?
Place at the beginning of the DNA strand where the RNA polymerase binds to in order to read the DNA
What is a operator?
In between the promoter and genes, it blocks the RNA from reading unless repressor protein from operator is taken away
How does operon-level gene regulation differ from epigenetic regulation?
It’s not really based on what’s present in the outside environment, but more of what proteins are present/not present in the body and what is expressed due to that
What is the Antibiotic Selection Process?
Technique used to identify/isolate bacteria found in foreign DNA (cloned or recombinant) by using antibiotic resistance markers
What is Transformation Efficiency?
How many cells pick up plasmid relative to how much plasmid you add in total
