1
Aim: What are some applications of Genetic Engineering?
Genetic Engineering is a process that is used to the alter the genetic instructions in organisms.
2
Genetic Engineering Review:
A gene is combined with the DNA of another organism. DNA from Organism 2 This process is called: DNA from Organism 1 GENE SPLICING The combined DNA is called: Recombinant DNA Cell of an organism The recombinant DNA is inserted into the cell of another organism.
3
What is the end result? A genetically engineered organism Recombinant
DNA Cell of an organism
4
Applications of Genetic Engineering:
Scientists genetically alter the DNA of bacteria to produce human proteins. How many pieces of bacterial DNA do you see? 2 What are they called? Chromosome and a Plasmid
5
Bacterial Chromosome vs. Human Chromosome
X
6
Bacteria also have PLASMIDS
Plasmids are small, circular DNA molecules that are found in some bacteria. Scientists alter the genetic instructions found in the Plasmids.
7
How can we alter the genetic material of bacteria to produce human insulin?
Step 1: DNA is removed from a human cell and insulin gene is cut out with Restriction Enzymes.
8
How can we alter the genetic material of bacteria to produce human insulin?
Step 2: Plasmid is removed from a bacterial cell and is cut with Restriction Enzymes.
9
How can we alter the genetic material of bacteria to produce human insulin?
Step 3: Insulin Gene and Bacterial Plasmid are ______ together to form ____________ Spliced Recombinant DNA
10
How can we alter the genetic material of bacteria to produce human insulin?
Step 4: Recombinant DNA is inserted into a bacterial cell.
11
How can we alter the genetic material of bacteria to produce human insulin?
Step 5: Bacteria undergo ________ reproduction and are capable of producing the protein insulin. Asexual
12
Scientists can also genetically alter foods:
Genetically modified foods can be engineered to produce natural pesticides.
13
Scientists can also genetically alter foods:
Genetically modified foods can be engineered to increase their content of vitamins.
