Enzymes
This type of enzyme recognizes specific DNA sequences and cuts the DNA at or near these sites.
What is a restriction enzyme?
The process of removing DNA from a cell to study or manipulate it.
What is DNA extraction?
This process involves making changes to an organism’s DNA for practical purposes.
What is genetic engineering?
The medical procedure that aims to replace faulty genes with functional ones.
What is gene therapy?
A potential benefit of GMOs.
What is reducing pesticide use, increasing crop yield, or improving nutrition?
A restriction enzyme recognizes this type of sequence, which reads the same forward and backward.
What is a palindrome?
DNA fragments move through a gel from this charge to this charge.
What is negative to positive?
A small, circular piece of DNA found in bacteria that is often used in genetic engineering.
What is a plasmid?
This process involves choosing organisms with desirable traits to reproduce, gradually enhancing those traits over generations.
What is selective breeding?
A potential risk of GMOs.
What is the possibility of allergic reactions, loss of biodiversity, overuse of herbicides, or unintended crossbreeding?
This technique is used to separate DNA fragments after they have been cut by restriction enzymes.
What is gel electrophoresis?
The purpose of this biotechnology technique is to separate and analyze DNA fragments based on size.
What is gel electrophoresis?
Combining DNA from two or more different sources creates this type of DNA.
Combining DNA from two or more different sources creates this type of DNA.
The difference between reproductive and therapeutic cloning.
What is reproductive cloning creates whole organisms, while therapeutic cloning creates stem cells for medical treatment?
One ethical concern about cloning humans.
What is reduced genetic diversity, loss of individuality, or potential misuse?
Two reasons why Gel Electrophoresis would be performed.
What is forensics, paternity tests, gene analysis, study the structure and function of proteins?
Before scientists can analyze DNA, they must make many copies of a specific DNA segment using this technique.
What is polymerase chain reaction (PCR)?
Scientists use this process to create genetically identical copies of organisms or cells.
What is cloning?
One goal of genetically modifying crops.
What is increasing yield, improving resistance to pests, or enhancing nutritional value?
A potential risk of gene therapy.
What is unwanted immune system reaction? Targeting the wrong cells? Infection caused by the virus? Possibility of causing a tumor?
This unique pattern of DNA bands, created through gel electrophoresis, can be used to identify individuals.
What is a DNA fingerprint?
A genetically modified organism that contains DNA from a different species.
What is a transgenic organism?
One major concern with this process is that it reduces genetic diversity, making populations more vulnerable to disease and environmental changes.
What is cloning?
An example of an modern organism produced from selective breeding.
A key ethical question regarding gene therapy.
What is killing embryos in the process?
