Choose the statement that best describes gene therapy.
the process of producing crops that are resistant to insects
the process of using DNA taken from a crime scene to identify a suspect
the process of inserting normal genes into human cells to correct genetic disorders
the process of creating an identical organism or gene
Why is Dolly the sheep considered a clone?
the source of Dolly's DNA is a single cell taken from an adult donor
the DNA molecules in each of Dolly's cells are different
Dolly has a mix of genes from her foster mother and the sheep that donated a nucleus of one of its cells
Dolly is genetically identical to her offspring
If a farmer asked the ethical question "What are the long-term effects of creating crops that are immune to pesticides and diseases?" what topic would they discussing?

farmers will be able to increase their farms and make more money
the long-term effects of these foods are unknown
a decrease in genetic diversity of plants
genes for pesticide resistance might transfer to weeds by cross-pollination
The parents of a new baby believe they brought the wrong child home from the hospital. Gel electrophoresis was performed using DNA samples from the parents and the child. A section of the gel
electrophoresis results is shown below. Which conclusion is valid based on the gel electrophoresis results?
They have the correct child, because her genetic information is identical to that of the father.
They have the wrong child, because her genetic information does not match that of either parent.
They have the correct child, because her genetic information came from both parents.
They have the wrong child, because her genetic information matches only that of the mother.
Which is a human protein produced by bacteria as a treatment for diabetes?
What do scientists hope to accomplish through stem cell research?
Developing vaccines for lead poisoning
Growing organs for transplant surgery
Developing restriction enzymes to cut DNA
Considering some of the ethical issues surrounding the use of DNA technology, which is a way gene therapy impacted society?
by mapping the genetic make-up of non-living objects
by engineering genes to be able to replace a person’s DNA
by using genes in psychiatry to provide therapy to patients
by correcting genetic disorders with insertion of normal genes
