A new study has revealed a positive shift in public sentiment towards one aspect of agricultural biotechnology, showing that gene editing consistently receives higher favorability ratings than GMOs in both social and traditional English-language media. (sciencedaily.com)
A new study from the Alliance for Science, an initiative based at the Boyce Thompson Institute, has revealed a positive shift in public sentiment towards one aspect of agricultural biotechnology, showing that gene editing consistently receives higher favorability ratings than GMOs in both social and traditional English-language media. (sciencedaily.com)
Typically, in this context, biotechnology refers to the processes that involve the transfer of transgenes from organisms to plants hence food production. (gmo-safety.eu)

The released transgenes can further be transferred to the nucleus, transcribed and translated. (nih.gov)

Gene editing and genetically modified organisms (GMOs) have been topics of significant debate in recent years. (sciencedaily.com)
However, some of the issues that have to be addressed with a high level of stringency are the potential Allergenicity associated with genetically modified plants/crops. (gmo-safety.eu)

In view of this, it has been considered necessary by biosafety regulations of individual countries to test the feasibility of GMOs in contained and controlled environments for any potential risks they may pose. (hindawi.com)
The present analysis is designed to facilitate additional improvements in the APHIS system, which will be necessary to meet future challenges of assessing potential environmental risks of a large number of diverse and novel transgenic products. (nationalacademies.org)
The next section will delve into these important ethical implications in genetic engineering, highlighting the need for thoughtful reflection on both the risks and rewards associated with manipulating genes to improve human health. (willtoexist.com)

Five Ethiopian tropical maize genotypes were evaluated for their regeneration potential through somatic embryogenesis to establish regeneration system and select regenerable genotypes as prerequisites in applying genetic transformation for improved drought stress tolerance. (scialert.net)
Somatic-cell nuclear transfer, the technique by which Dolly was created, was first used 40 years ago in research with tadpoles and frogs. (who.int)
The nucleus of an adult somatic cell (such as a skin cell) is removed and transferred to an enucleated egg, which is then stimulated with electric current or chemicals to activate cell division. (who.int)

This can be achieved either by cytometric techniques or by nucleic acid-based methods ( 3 ). (iiarjournals.org)

So far, viral and nonviral approaches suffer from major drawbacks hindering efficient gene therapeutic applicability: the immunogenicity of viral systems on the one hand, and the low gene transfer efficiency of nonviral systems on the other hand. (genengnews.com)
