Plant genetics

When organisms pass their genes on to future generations, they include more than the code spelled out in DNA. Some also pass along chemical markers that instruct cells how to use that code. The passage of these markers to future generations is known as epigenetic inheritance. It’s particularly commo

Interested in becoming a Clinical Aromatherapist? We offer an Online Clinical Aromatherapy Certification Course Recently I was reading through a dialogue in an aromatherapy forum and was interested in how some individuals began their dialogue with “I am a clinical aromatherapist”. I also see this on occasion when ‘surfing’ the web, so to speak. So […]

GMOs might be lurking in your favorite soy burgers, corn tortillas, or other foods. Learn how to avoid them by taking this short quiz.

(August 2003) Even before the creation of transgenics, the alteration of crops to improve their production was performed through selection. In fact, this selection has been going on for thousands of years and only in the past few centuries has it become a dedicated science onto itself. So, why has there been a push to

Domesticated crop plants tend to have low genetic diversity because they have usually been selectively bred from varieties that are genetically related. This cross-breeding approach produces high-yield varieties, but it can also increase susceptibility to disease and pests.[1] Cross-breeding these…

Humankind unwittingly dabbled in genetic engineering 10,000 years ago, when early farmers saved seeds from their most vigorous plants — those with the hardiest genes — for the next year’s crops. We’ve come a long way since then.

One of the most revolutionary discoveries of the century, the CRISPR gene-editing system is built on a bacterial defense mechanism that allows scientists to make precise edits to DNA. Now scientists at MIT have discovered a new class of enzymes called OMEGAs that perform a similar function – and…

Genetically modified organism, organism whose genome has been engineered in the laboratory in order to favor the expression of desired physiological traits or the generation of desired biological products. Learn more about the development and uses of genetically modified organisms in this article.

As the Supreme Court debates the patentability of human genes, the media argues about whether patents help or hinder genetic research. The Genetic Literacy Project asserts that when public access and private interests are balanced, intellectual property protection can play an important role in spurring innovation.
