Readers write - How GMO's are made - Second article in a series explaining GMO's.

REFERENCES are available on the web: “GMO Myths and Truths” and “Physicians and Scientists for Responsible Application of Science and Technology”.

Making GMO's consists of 3 main steps:

1.     First, genetic material from various organisms is isolated, cut and rejoined with viruses or bacteria as “gene carriers” because viruses and bacteria are very good at getting into cells.

2.     This new “recombinant DNA” is stitched with antibiotic “marker genes” to make it easy to identify which cells have taken up the foreign genetic material and survived.
3.     The vectors inside the cells that have survived are then mechanically injected into the target organism using a fine glass pipette in the case of animal embryos, or fired into the cells of plants using a “gene gun”.

This process is imprecise and unpredictable. It is based on an obsolete understanding of genetics. Recent findings show there are no simple one-to-one relationships between genes and traits, but that the expression of a gene is the result of its interaction within the whole organism. 

So using viruses and bacteria stitched with antibiotic to insert a cold-resistance fish gene into a plant can have disastrous results, such as creating new disease-causing viruses and bacteria, and spreading antibiotic resistance genes to the pathogens to make the diseases untreatable.

Next week: Who makes GMO's and why?

I have been a resident of Coldstream since 1976. I have had 15 years of experience on Council, 3 years as Mayor. As a current Councillor I am working to achieve fair water and sewer rates and to ensure that taxpayers get fair treatment. The current direction regarding water supply is unsustainable and I am doing all I can to get the most cost effective water supply possible.
