Biotechnology is how scientists manipulate living organisms to gain benefits for society. We have been using biotechnology for centuries to create food and even pets. Today, we are bombarded with biased information that cloud our understanding of biotechnology.
Genetically Modified Organisms (GMO)
Gene Cloning
Genetic cloning is the production of multiple copies of a gene.
DNA Cloning Assignment |
What if you want to clone an entire organism and not just one gene?
Cloning is a controversial process that involves creating a genetically identical organism, or clone, from the genetic material of an individual. Clones are created by inserting a nucleus from an individual into an unfertilized egg. The egg will develop as if it had been fertilized to create a new living organism.
Polymerase Chain Reaction (PCR)
The polymerase chain reaction (PCR) makes many copies of a gene or other DNA segment. This might be done in order to make large quantities of a gene for genetic testing. PCR involves three steps: denaturing, annealing, and extension. They are repeated many times in a cycle to make large quantities of the gene.

Gel Electrophoresis
Gel Electrophoresis is a technique used by scientists to separate mixtures of DNA, RNA, or proteins according to molecular size. Gel Electrophoresis creates a unique pattern based on the DNA, RNA, or proteins present. This unique patter is called your DNA Fingerprint
DNA Fingerprinting is essential for forensic science and paternity exams.
Scientist will run a gel electrophoresis on any DNA or protein samples found at crime scenes. Using the DNA fingerprint created from each suspect, crime scene investigators can select which suspect is guilty.
Can you determine which suspect is guilty?
