When food is genetically modified, its genes are changed by scientists to produce new traits that farmers and consumers want from their food. for example, with genetic modification, a plant that is eaten by a certain type of insect could be changed in such a way that it tastes bad or is even dangerous to that insect. with genetic engineering, food items can become more resistant to disease and pests, last longer on store shelves, or have higher nutritional value per serving. what is genetic modification?

Respuesta :

Genetic modification involves the transfer of a segment of DNA from one organism to another so as to change its genetic constitution.

How are organisms modified?

  • Genetic engineering or genetic modification is a technology that deals with the manipulation of an organism’s genes by transfer of piece of DNA from other organism.
  • Genetically modified plants have been produced by humans from thousands of years by out crossing, selective breeding and selection.
  • Nowadays plants, animals and even microorganisms are genetically modified by targeted removal of a required gene from one organism and integrating it to the genome of another.
  • The 3 types of genetic modification are crop breeding by traditional ways, genetic modification and genome editing.
  • Endonucleases help to cut out the required gene and vectors act as vehicles to transfer the required gene to new organism.
  • To produce a GM plant, new DNA is transferred into plant cells. The cells are then grown under controlled conditions where they develop into complete plants. The seeds produced by these plants will inherit the new DNA.
