Transgenic Maize

Souther Mexico

Corn is a staple grain of the world’s food supply.

Southern Mexico is a world center of biodiversity for maize, with many locally adapted domesticated varieties, called landraces.

Biodiversity is the degree of variation of life.

In 2001, Mexican scientists found DNA in Oaxacan farmers’ maize that seemed to match genes from genetically modified corn.

To genetically engineer crops, scientists extract genes from the DNA of one organism and transfer them into the DNA of another organism of a different species.

The genes are called transgenes, and the new organisms are transgenic plants.

Transgenes-are genes that are transfered naturally like the way Borlog did it.

Their findings were published in Nature

Their findings were published in Nature, but the findings were disputed and, bowing to criticism, Nature stated that the study should never have been published.

Further research has confirmed their findings.

The question is how (positively and negatively) genetically modified crops may affect people and the environment.
