CH 2 The Historical Development of Biotechnology
Terms in this set (18)
started biotechnology; allowed humans to manipulate plant traits.
vertical gene transfer
Transfer of genetic information from parents to offspring
Shape of DNA
Transferring bits of genetic information from one organism to another, allowing the expression of desirable traits in the recipient organism.
Horizontal gene transfer
natural genetic engineers transfer of genetic material between cells and is not its offspring.
removing a gene from one organism to another organism
Biotechnology is a relatively new phenomenon
False. Biotechnology was been used to alter living organisms for human use began in early agriculture between 7,000 and 12,000 years ago.
Agriculture contributes to early bartering and money exchange systems.
One of the first methods for storing food was by producing fruit juice and then fermenting the fruit juice into wine
A purebred strain is a type of plant or animal that results from the crossing or mating of parents that are different
False. A hybrid strain is a type of plant or animal that results from the crossing or mating of parents that are different.
Gregor Mendel observed his pea plant and found that short-stemmed plants produce only more short-stemmed plants and that long-stemmed plants produce only more long-stemmed plants.
Alexander Fleming discovered the antibiotic penicillin accidentally when his experiments with bacteria became contaminated with mold.
Bull semen has been successfully stored for as long as 30 years.
Microbes can function as natural genetic engineers and can complete horizontal gene transfer.
The first plant was grown in vitro in the 1930s.
False. The first plant was grown in 1950 using the genetic code.
Genetic engineering is the only type of biotechnology that scientists are currently using and studying
False, genetic engineering is a very large part of biotechnology, however many new and breakthroughs in the use of living organisms do not rely on genetic engineering.
all organisms share a "universal language" and by understanding this led to many scientific discoveries.
Used the blood of sheep that survived a diseased called anthrax and injected it into other sheep who then never become sick. Led to vaccines.
