PowerPoint Presentation On Genetically Engineered Plants

PPT On Genetically Engineered Plants

Presentation Transcript:
1. Genetically Engineered Plants

2. Introduction Genetic modifications are a result of technology that has altered the DNA of living organisms( plants, animals, bacteria). Other related terms- Genetic engineering Transgenics Recombinant DNA technology

3. Transgenic plants have been developed for a variety of reasons- longer shelf life disease resistance herbicide resistance pest resistance enhanced taste and quality reduced maturation time higher yielding crops more efficient use of land can save money and promote higher profits

4. Gene Technology Genes code for proteins The sequence of bases in the DNA of a gene contains information to make a protein Transferring the information from DNA to protein is called gene expression Process of formation of protien from DNA:- During transcription, DNA is copied into messenger RNA (mRNA) chains. During translation, mRNA moves to the ribosome, where the building blocks of proteins (amino acids) are added . This sequence of amino acids ultimately forms a protein.

5. Golden Rice Created by Peter Beyer and Ingo Potrykus of the Institute of Plant Sciences at the Swiss Fedral Institute of Technology. Designed to produce β carotein, a precursor of Vitamin A, in the part of rice the endosperm. Created by transforming rice with two β-carotene biosynthesis genes: psy (phytoene synthase) from daffodil (Narcissus pseudonarcissus) crt1 from the soil bacterium Erwinia uredovora

6. Vitamin A deficiency Weakens the immune system Can lead to blindness which increases the risk of death Is entirely preventable!
