In the present study attempts were made to assess the phytochemical‚ nutraceutical and chemical composition‚ pharmacological properties and safety profiles of C. spinosa. Powder microscopy revealed characteristics features of C. spinosa. Preliminary phytochemical screening of flower buds of C. spinosa L. revealed the presence of alkaloids‚ reducing sugars‚ carbohydrates‚ saponins‚ phenolic compounds‚ tannins‚ anthraquinones and lignins

This shows that DNA bound to Cren7 is more compact than bare DNA. D. Atomic force microscopy (AFM). A DNA molecule or a protein-DNA complex is put on a flat mica surface. The surface can be scanned with a small tip of the AFM. The surface can be visualized on a nanometer scale. An image of bare DNA (top) and DNA bound to Alba1 (bottom)

Lesson 02.08 DBA/Module Exam Lesson 02.01: Chemistry of Life · Explain why biological macromolecules are important for everyday life. Cells make large macromolecules by bonding smaller molecules together into chains called polymers (from the Greek polys‚ "many‚" and meris‚ "part"). Polymers are large molecules composed of many identical or similar subunits called monomers. There are four categories of biological macromolecules that provide energy and structure to living organisms and their cells

The History of Forensic Science Law Enforcement has used forensic science for years to help solve puzzling crimes. But not to many people know just how long the art of forensic science has been around. For example evidence of fingerprints were found in paintings and prehistoric rock carvings made by humans. The Chinese have probably used forensics much longer than most civilizations. For example back in the 700’s they used fingerprints to find out the identity of documents and clay sculptures.

Biology 1003 - Cells: Size‚ Structure and Microscopy Introduction What is life? What are the key factors that biologists have defined that apply to every single organism on the planet? In the 17th century‚ due to the amazing advancement of the microscope‚ biologists created a theory to differentiate the living from the non-living called the cell theory. One concept from the theory is that all living organisms are composed of one or more cells. The importance of studying cells is akin to the

Autoradiography Presenter: Miranda Grounds References: Alberts‚ p174-176‚ 730. Rogers A (1979) Techniques of autoradiography. 3rd Edition. Elsevier‚ North Holland pp429. Radiography is the visualisation of the pattern of distribution of radiation. In general‚ the radiation consists of X-rays‚ gamma (g ) or beta (b ) rays‚ and the recording medium is a photographic film. For classical X-rays‚ the specimen to be examined is placed between the source of radiation and the film‚ and the absorption
