Q: A gene can behave in different ways depending on the genome in which it is contained. How can genetic engineers perform tests to be sure that a gene transferred from, say, a bacterium into a plant will result in the desired effect only?

A: Thank you for your question. Alan McHughen, CE biotechnology specialist and geneticist, discussed the safety of inserted genes in a recent article. An excerpt is below: “…To ensure the inserted gene does what it is supposed to, various molecular, chemical and biological tests are conducted on the GM plant, animal or microbe to check that the inserted DNA sequence is intact and the expressed protein is functional before the GMO is commercialized. They are also extensively tested for... Continue Reading
Q: How do you ensure that a piece of genetic code produces the desired protein and not a multitude of others. How do you keep junk DNA from becoming active and causing undesired proteins from being produces.

A: Great question. Alan McHughen, CE biotechnology specialist and geneticist, provided a related response that might be of interest to you; an excerpt is below: “Genes are composed of long stretches of DNA, which is composed of the chemical building blocks we abbreviate as A, T, C and G (adenine, thymine, cytosine and guanine, respectively). Just as in the human language English, in which thousands of words are composed of specific sequences of 26 letters, in biology all genes in all... Continue Reading

A: Kevin Folta, Interim Chair and Associate Professor in the Horticultural Sciences Department at University of Florida, has created a video response to your question. Please view the video here: . A transcript of the video is included below: Well, thank you for the question. This is a really interesting one to me because I’m really interested crop domestication. How did the wild weeds that were dotted all over the globe turn into elite foods that have tremendous nutritional... Continue Reading

A: Kevin Folta, Interim Chair and Associate Professor in the Horticultural Sciences Department at University of Florida, has created a video response to your question. Please view the video here: A transcript of the video is included below: So what are the big differences between GMO technology, cross-breeding and simple cross-pollination? Let’s start with the last one. Cross-pollination is simply a process where two sexually compatible plants happen to cross by virtue of pollen, which... Continue Reading

A: Within the context of biotech crops, adventitious presence or AP occurs when trace amounts of an agricultural biotech product that has not been approved for commercial use (e.g., research events, field trial escapes) by any competent government authority, but is found in the commercial crop or food supply despite best agricultural and manufacturing practices. In the context of agricultural biotechnology, a similar concept of low level presence or LLP is defined as the unintentional, low... Continue Reading
