How does genetic engineering?

Genetic engineering is the process of manually adding new DNA to an organism. The goal is to add one or more new traits that are not already found in that organism.
A.

What are the main steps involved in genetic engineering?

This method is also more specific in that a single trait can be added to a plant.
  • Step 1: DNA Extraction. The process of genetic engineering requires the successful completion of a series of five steps.
  • Step 2 : Gene Cloning.
  • Step 3 : Gene Design.
  • Step 4 : Transformation.
  • Step 5 : Backcross Breeding.
  • What is a genetic engineer?

    Genetic engineering, also called genetic modification or genetic manipulation, is the direct manipulation of an organism's genes using biotechnology. A construct is usually created and used to insert this DNA into the host organism.
  • How is DNA important in genetic engineering?

    A small piece of circular DNA called a plasmid? is extracted from the bacteria or yeast cell. A small section is then cut out of the circular plasmid by restriction enzymes, 'molecular scissors'. The gene for human insulin is inserted into the gap in the plasmid. This plasmid is now genetically modified.
  • How is DNA extracted from a cell?

    There are three basic and two optional steps in a DNA extraction: Cells which are to be studied need to be collected. Breaking the cell membranes open to expose the DNA along with the cytoplasm within (cell lysis). Lipids from the cell membrane and the nucleus are broken down with detergents and surfactants.
B.

What is the process of genetic modification?

A GMO (genetically modified organism) is the result of a laboratory process where genes from the DNA of one species are extracted and artificially forced into the genes of an unrelated plant or animal. This process may be called either Genetic Engineering (GE) or Genetic Modification (GM); they are one and the same.
  • How long have we been eating genetically modified foods?

    Research and development of GMOs have been going on for more than 30 years, with the first wide scale planting of GE crops in 1996. The first genetically modified food designed and approved for human consumption that came to market in 1994 was the FlavrSavr tomato. The “why” depends on the “what”.
