Part of a three-part series presented by David Cove, coauthor of A primer of genetics. Dr. Cove addresses the mechanics of DNA replication and the subject of genetic engineering. This episode discusses how organisms replicate. Dr. David Cove describes the structure and function of DNA as he covers how coding sequences and promoters work together to create proteins from amino acids. DNA's remarkable suitability as a medium for duplicating the blueprints of life both rapidly and accurately in a simple yet precise language is emphasized.
Part of a three-part series presented by David Cove, coauthor of A primer of genetics. Dr. Cove addresses the mechanics of DNA replication and the subject of genetic engineering. This episode introduces the process of genetic engineering. How does cDNA differ from normal DNA? Can a bullet really implant genes? And why is a gene for bioluminescence so valuable to researchers? This program answers those and other questions. Dr. David Cove deftly explains how reverse transcriptase is used to isolate genes, how isolated genes are cloned, how cloned genes are delivered via benign virus or "DNA gun," and how the effects of delivered genes are tracked by reporter genes.
Part of a three-part series presented by David Cove, coauthor of A primer of genetics. Dr. Cove addresses the mechanics of DNA replication and the subject of genetic engineering. This episode surveys past and probable future applications of genetic engineering while calmly presenting possible benefits and liabilities. Many scientists and consumers believe that genetic engineering will vastly improve life on Earth, while others believe it will spell the ruin of the planet. What are the facts behind the rhetoric and the hysteria? The case is stated for genetically modified crops; microorganism-produced human insulin; engineered vaccines, which involve no disease-causing microbes; and the diagnosis and cure of gene-based diseases. The concept of risk assessment is also defined.
Using archival photos and interviews with descendants of the Chiricahua Apaches, the program highlights the clash between Indian and white cultures and portrays the effects on an Indian society faced with the loss of its land and traditions.

"In June, 1993, the Golden Venture, a freighter carrying 300 undocumented Chinese passengers, ran aground off New York. The deaths and deportations that followed became a crucial turning point, ushering in a new, repressive era that has led America (once a beacon of liberty) to tighten its borders"--Container.
