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: 1)Scientists can target and identify a gene. 2)Cut the desired gene with restriction enzymes.
3
Genetic Engineering Review: 3)The gene is combined with the DNA of another organism. 4)The recombinant DNA is inserted into the cell of another organism. This process is called: GENE SPLICING Cell of an organism DNA from Organism 1 DNA from Organism 2 The combined DNA is called: Recombinant DNA
4
What is the end result? Cell of an organism A genetically engineered organism Recombinant DNA
5
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
6
Bacterial Chromosome vs. Human Chromosome Bacterial Chromosome Human Chromosome X
7
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.
8
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.
9
Step 2: Plasmid is removed from a bacterial cell and is cut with Restriction Enzymes. How can we alter the genetic material of bacteria to produce human insulin?
10
Step 3: Insulin Gene and Bacterial Plasmid are ______ together to form ____________ Recombinant DNA Spliced How can we alter the genetic material of bacteria to produce human insulin?
11
Step 4: Recombinant DNA is inserted into a bacterial cell. How can we alter the genetic material of bacteria to produce human insulin?
12
Step 5: Bacteria undergo ________ reproduction and are capable of producing the protein insulin. Asexual
13
Genetically modified foods can be engineered to produce natural pesticides. Scientists can also genetically alter foods:
14
Genetically modified foods can be engineered to increase their content of vitamins.
15
