Many recent imaging modalities in medicine‚ such as magnetic resonance imaging (MRI)‚ computed tomography (CT)‚ digital mammography also generate images directly in digital form. Diagnostic imaging is an invaluable tool in medicine today. These imaging modalities provide an effective means for non-invasive mapping of the anatomy of a subject. These technologies have greatly increased

The Invention of the electron microscope occurred in 1931. The electron microscope is used to see molecular levels of the cell that cannot be seen by the naked eye. This has helped us drastically improve our understanding of cells. 5. The discovery of the mechanisms of light-independent reactions of photosynthesis was discovered in 1953. This discovery

Brianna Noriega In order to analyze a dna molecule in a molecular biology lab you must determine the length in nucleotide pairs. Electrophoresis is an extremely useful tool in order to compare the mobility on agarose gels with dna markers of known lengths. Dna is a polymer that is negatively charged due to the sugar phosphates. When dna is on an electric field such as the electrophoresis gel the different lengths of dna migrate at different rates when they move through the porous gel. The ends

Designer Babies Designer Babies is a very controversial topic in regard to the moralities involved. Pre-implantation genetic diagnosis (designer baby) refers to the genetic structure being modified prior to the implantation or even prior the fertilization of the embryo. While a parent may have varying reasons for participating in the procedure‚ many people question the moral and ethical side of the situation. A common use for designer babies concerns possible uses of gene therapy techniques to create

Edwin Southern invented the molecular technique of Southern Blotting in 1975. This technique is very useful because of its ability to detect a specific DNA sequence from a large amount of DNA ⎯ even from the whole genome. This specific sequence can be found through a combination of two different techniques: Agarose Gel Electrophoresis and Hybridization‚ which is known as Southern Blotting. This technique if performed in three phases: (I) prepare the gel and (II) make the blot‚ (III) hybridize and
