1. Plasmids Plasmids are closed circular‚ double-stranded‚ extrachromosomal DNA molecules which occur naturally in bacteria‚ yeast‚ and some higher eukaryotic cells‚ and exist in a parasitic or symbiotic relationship with their host cell (Lodish et al.‚ 2000) The main application of plasmids is as cloning vectors in gene cloning. In gene cloning‚ a fragment of DNA‚ containing the gene to be cloned is inserted into a circular molecule called the “vector” to produce recombinant DNA molecule. Plasmids

Biotechnology has greatly impacted the way we live today. It is the use technology on living organisms in order to produce substances useful to today’s society. For example‚ the invention of Invitro Fertilization‚ also known as IVF. Invitro Fertilization is when an egg (the ova) is surgically removed from women in order to create fertilization inside a test tube. IVF was invented for women who were born barren/ infertile (unable to bear offspring) or women who simply cannot reproduce‚ so that

eight Millennium Development Goals would not be met unless decisive action was taken to stabilize ecosystem services.We use the term ‘modern biotechnology’ to describe techniques which are not used in traditional breeding or selection‚ such as the manipulation of genetic material and the fusion of cells. The more sophisticated forms of modern biotechnology‚ including genomics and proteomics‚ present unprecedented opportunities for Africa to address some of its problems and stimulate economic growth

chimps but not necessarily the biotechnology part of it. For example‚ they built small holding cells for the chimps‚ and puzzles to assess their brain development. In this story the drug seemed to be effective on humans‚ until the grandfather became resistant to it. This applies to the real world‚ because even if something in biotechnology seems like it would have great benefits‚ it can wear off or have side effects since you’re disrupting nature. Biotechnology also has the potential for great

Use of forensics and biotechnology in Criminal Justice Abstract “Proof” is defined as an act or process of showing that something is true (Merriam-Webster’s online dictionary). In criminal justice‚ proof is seemingly the most important factor in crime solving. As the old saying goes “it’s not what you know‚ it’s what you can prove.” The method of gathering and examining information is known as forensic science; a prominent resource in the law enforcement field. Whether on television or in

Archaea - very primitive; live in extreme habitats 2. Eubacteria - more advanced 3. Eukaryota - all life forms with eukaryotic cells (have a nucleus) Use of ribosomal RNA sequences for classification rRNA is found in all cells rRNA is easy to isolate Analyzed to determine the exact sequence of nucleotide bases
