Question

Which is a concern of scientists when genetically modifying plants

Answer 1

There are many reasons for concern. The GE crops are created by using a new genetic process to insert an unknown amount of DNA that has the potential to spread in the environment in unpredictable ways. Independent research on the effects of eating these new foods has been suppressed when it shows evidence that the GMOs are harmful to health. Hope this helped. ;)

Answer 2

But some scientists and members of the public have expressed concern that the genetic engineering of plants could result in unsafe foods, do irreparable harm to beneficial organisms, and spur the uncontrollable growth of weeds.
