HOW DO WE KNOW?
In this chapter, we focused on a number of interesting applications of genetic engineering, genomics, and
(a) What experimental evidence confirms that we have introduced a useful gene into a transgenic organism and that it performs as we anticipate?
(b) How can we use DNA analysis to determine that a human fetus has sickle-cell anemia?
(c) How can DNA microarray analysis be used to identify specific genes that are being expressed in a specific tissue?
(d) How are GWAS carried out, and what information do they provide?
(e) What are some of the technical reasons why gene therapy is difficult to carry out effectively?

- What are some of the ethical concerns arising out of the information produced by the Human Genome Project?arrow_forwardDiscuss three important advances that have resulted from gene cloning.arrow_forwardIn contrast with the genomic manipulations of animals and plants described in this chapter, human genetherapy is directed specifically at altering the genomes of somatic cells rather than germ-line cells.Why couldn’t or wouldn’t medical scientists try to alter the genome of human germ-line cells?arrow_forward
- Recombinant pharmaceuticals (for the production of insulin, human growth hormone or blood clotting factors) Question: What are controversies or ethical dilemmas surrounding this genetic technology or process?arrow_forwardIf you were offered the chance to have the genome of your newborn sequenced at a cost of 1,000, would you do so?arrow_forwardAn unapproved form of gene therapy, known as enhancement gene therapy, can create considerable ethical dilemmas. Why?arrow_forward
- Describe the goals, processes, and outcomes of the Human Genome Project. Who were the major "players" involved? What were the successes and challenges?arrow_forwardWhat are the Major Ethical Issues of Modern Biotechnology?arrow_forwardWhich goals of the Human Genome Project do you think are themost important? Why? Discuss the types of ethical problems thatmight arise as a result of identifying all of our genes.arrow_forward
- CRISPR techniques allow scientists to modify specific genes while sparing all others, thus clarifying the association between a given gene and its consequence to the organism. If this technology can change the future of Medicine, what specific benefits CRISPR can bring to genetic testing or analysis? How can CRISPR help to enhance gene therapy or treatment of genetic diseases?arrow_forwardWhat are the ethical implications of genetic engineering and cloning?arrow_forwardWhat advancements in genetic engineering or modification have occurred over the last 20 years and how will this shape our future? Identify and explain at least one biotechnology technique that is involved with genetic engineering.arrow_forward
