  3. 1-Why The Knowledge Of Biochemistry Is Essential For Medical Students

  4. ANSWER ~~Biochemistry is the study of the chemical nature of living things and the chemical transformations that happen within them. It is integrally tied into the studies of genetics, immunology, physics, and chemistry.Biochemistry offers the foundations and explanations for the essential processes of life.~~~Biochemistry is the collection of every organic chemical reaction in living organisms. Without functioning biochemical reactions, life in any form would not exist. In humans, at the most basic level, properly functioning balances ofchemical reactions within the body are responsible for health while disfunctioning balances of chemical reactions are responsible for diseases. Biochemical reactions are responsible for everything from metabolism to genetics. The study of biochemistry is important for deepening our understanding of how organisms function. Understanding biochemistry plays a large role in understanding the genetic basis for some diseases, the pharmacological effects of medications, the intricacies of metabolism, and the most basic differences between organisms. 

  5. Biochemistry is the science concerned with the chemical basis of life. The major objective of biochemistry is the complete understanding, at the molecular level, of all the chemical process as associated with living cells. Biochemistry encompasses large areas of cell biology, of molecular biology, and of molecular genetics. The knowledge of biochemistry is essential to all life sciences. Biochemistry and medicine are intimately related. Health depends on a harmonious balance of biochemical reactions occurring in the body, and disease reflects abnormalities in bimolecular, biochemical reactions, or biochemical processes. Biochemical approaches are often fundamental in illuminating the causes of disease and in designiang appropriate therapies

  6. 2-What Methods Are Used For DeterminingThe Structure Of Biomolecules??

  7. Biomolecules are the building blocks of life and perform important functions in living organisms. There are several types of biomolecules. Of most importance are the nucleosides and nucleotides that make up DNA and RNA, the molecules that are involved in heredity. There are also the lipids which function as the building blocks of biological membranes and as energy providing molecules

  8. Main articles: Protein structure and Nucleic acid structure determination……. Structure probing is the process by which biochemical techniques are used to determine biomolecularstructure.Thisanalysis can be used to define the patterns which can infer the molecular structure, experimental analysis of molecular structure and function, and further understanding on development of smaller molecules for further biological research.[11] Structure probing analysis can be done through many different methods, which include chemical probing, hydroxyl radical probing, nucleotide analog interference mapping (NAIM), and in-line probing.[10] DNA structures can be determined using either nuclear magnetic resonance spectroscopy or X-ray crystallography. The first published reports of A-DNA X-ray diffraction patterns-- and also B-DNA—employed analyses based on Patterson transforms that provided only a limited amount of structural information for oriented fibers

  9. 3.What Are The Major Causes Of Disease? • Major causes of disease are following………1_bacterial infection like……..Streptococoistaphilococoigram +ve Bacteriagram –ve bacteria2_viral infection like……..Aids & Hapatitesdue to blood transfussion,smoking,alcohol abuse etc.3_SEVERE TRUMA4_INJURY5_DUE TO ACCIDENT6_DUE TO DOG OR SNAKE BITE ETC

  11. Define Proteomics:- Proteomics is the large-scale study of proteins, particularly theirstructuresandfunctions.Proteinsare vital parts of living organisms, as they are the main components of the physiological metabolic pathways of cells. The term Proteomics was first coined in 1997 to make an analogy with genomics, the study of the genome. The word proteome is a blend of proteine and genome, and was coined by Marc Wilkins in 1994 while working on the concept as a PhD student

  12. Define Stem Cell Biology:- Definition noun, plural: stem cells (1) An unspecializedcell characterized by the ability to self-renew by mitosis while in undifferentiated state, and the capacity to give rise to various differentiatedcell types bycelldifferentiation. (2) A cell that has not yet acquired a special function
