Which of the following sentences correctly makes use of terms from the introduction to biotechnology?
Genetic engineering can move genes from one species into another, creating a transgenic organism.
How do scientists generate large amounts of a particular piece of DNA they wish to work with?
They insert the DNA into a bacterial plasmid
Which of the following would be the first step in creating a transgenic cure for cystic fibrosis?
cloning the healthy CFTR allele
What is the difference seen between two alleles for a gene in RFLP analysis?
the number of fragments generated when each allele is cut by a restriction enzyme
A strain of virus in birds picks up avian DNA, infects a human host, and inserts the DNA into the human's genome. What can be said about this event?
A transgenic human has been created.
What event is necessary for a virus to move genes from organism to another?
The virus must insert its DNA into the genome of the host
How does an STR differ from one person to the next?
It differs in the number of times the sequence is repeated
How does gel electrophoresis help when analyzing samples of DNA?
It separates DNA fragments by length.
Which of the following is most similar to the process of creating a plant that expresses Bt toxins to ward off insects?
A strain of bacteria transfers an antibiotic resistance plasmid to another strain of bacteria
What is the current status of transgenic food products in the United Status?
Transgenic food is commonly found in the grocery store.
Why was A. tumefaciens used to transfer the gene for Bt toxin into plant cells?
The Ti plasmid of A. tumefaciens inserts itself into the plant chromosomes, taking the Bt gene with it.
Why do scientists make plants and farm animals that are transgenic for human antibodies and hormones?
This is a way to produce large amounts of these products cheaply.
the human genome has already been sequenced, why are researchers at the Human Genome Project now sequencing multiple humans?
The minor differences between each human's genome can teach us things about the causes of disease
Which technique can be used to determine if a patient carries a disease allele no matter which gene you may be trying to analyze?
probe array
Why is it more difficult to test for cystic fibrosis than to test for sickle-cell anemia?
There are many more disease alleles for cystic fibrosis than for sickle-cell anemia.
Which of the following have humans only accomplished by modern biotechnology?
create new alleles
After accounting for all the side effects associated with transgenic organisms, what has the National Academy of Sciences recommended regarding their use?
No serious side effects have been identified. Use with caution.
On the whole, how has biotechnology been used most successfully by humans?
It has been most successful at creating transgenic organisms to manufacture products for us.
