the plants and fruits we eat everyday are full with pesticides and herbicides in their genes. If a farmer uses quimicos to make fruit fly infertil so, it will dessaperar in two generations... what do you think we are eating when we eat an apple treated geneticly with this chemical andnd pesticide?

Thank you for your question. One of our experts will get back to you soon.

Thanks for the question, which I will address in two ways here.   1. What are three ways that organisms are modified by scientists? Here I will focus only on plants.   a. Agrobacterium: Agrobacterium tumefaciens (Agro) is a naturally occurring soil organism that causes a disease in plants called crown gall disease. In the late 1970s, Mary-Dell Chilton discovered that Agro actually transfers genes (DNA) from the Agro to the plant cell, where it becomes integrated into the plant... Read More

First of all, to clarify – hybridization is part of conventional breeding and conventional breeding uses hybridization to create new combinations of genes from parent varieties. For example, a disease-resistant wheat variety may be hybridized to a variety that makes flour better suited for making whole wheat bread. This is a common goal of most conventional breeding programs. It typically involves taking pollen from one parent and using it to fertilize another parent. The... Read More

Viroids are very small pieces of circular RNA that have the potential of causing plant diseases. These entities are infectious agents that are different from viruses because they have no protein coat encircling their genetic material. Thus far, viroids are only known to be effective infectious agents in plants. Viroids have not been associated with any animal disease, and they have not been found in animal cells and tissues.    Biotechnological tools are being used in...
