Understanding DNA: The Blueprint of Life and Its Impact on Biotechnology

DNA is the nucleic acid that contains the genetic information essential for the functions of all organisms. Composed of nucleotides, each consisting of deoxyribose, a nitrogenous base, and a phosphate group, DNA's structure includes four nitrogenous bases: adenine, cytosine, thymine, and guanine. The discovery of DNA's structure, attributed to Swiss scientist Friedrich Miescher in 1919, has paved the way for advancements in biotechnology. This includes traditional methods like wine and beer production, as well as modern techniques such as antibiotics, animal modification, and cloning.

  1. COMENIUS EUROPEAN PROJECT DNA IPSIA “Emilio Cavazza” - POMEZIA

  2. DNA is nucleic acid conteins genetic informations necessary to correct functions of all organisms.

  3. DNA is organic acid polymers, monomers called nucleotides Nucleotides are formed of three components: Deoxyribose, one nitrogenous base and phosphate group.

  4. There are four types of nitrogenous bases: • adenine • cytosine • thymine • guanine

  5. The discovery of DNA has been attributed to the swiss Scientist Friedrich Miescher. In 1919 he discovered nucleotide’s structure

  6. DNA 's structure

  7. Biotechnology Biotechnology based on the various changes that can be done on DNA to improve plants and animals, or develop organisms beneficial for man.

  8. Many people think that biotechnology was born recently,but existes already for thousands of years Traditional biotechnologies • Wine • Beer New biotechnologies • Antibiotics • Modified animals • Cloning

  9. Thank you for your attention
