Does molecular biology have a future?
Molecular and cell biology have a great deal to offer tropical medicine in the future. Over the last 20 years there has been a gradual shift in the emphasis of basic biomedical research from the study of disease in patients and their organs to its definition at the level of molecules and cells.
What are the recent advances in molecular biology?
1 Some of the most powerful new technologies include polymerase chain reaction (PCR) advances, “difference analysis” (that is, the discovery of different gene expression patterns between different cells), transgenic/gene knockout technology, and gene delivery to tissues/gene therapy.
What is one of the most interesting discoveries of molecular biology?
DNA Polymerase (1956) In 1956, Arthur Kornberg and his lab forever changed the world of molecular biology with the discovery of DNA polymerase from E. coli cells. In one instant, scientists were now finally capable of synthesizing new DNA sequences onto an existing DNA strand.
What is the scope of molecular biology?
Molecular biology pertains to the study of living systems at the molecular level, especially DNA and RNA, and provides a background for further work in the rapidly expanding areas of genomics, cell biology, biotechnology, microbiology, diagnostics, and therapeutics.
Why is molecular Medicine important?
Molecular medicine aims to diagnose and manipulate the molecular processes underlying disease and health. Central in all its activities is the knowledge of biological functioning of human beings at the most basic level.
Why do we use PCR to study DNA?
Using PCR, a DNA sequence can be amplified millions or billions of times, producing enough DNA copies to be analyzed using other techniques. For instance, the DNA may be visualized by gel electrophoresis, sent for sequencing, or digested with restriction enzymes and cloned into a plasmid.
What is a molecular technologist?
Molecular genetics technologists work in labs and study the role of genetics in medicine. Technologists analyze a patient’s DNA to research, diagnose, and treat many different diseases and disorders, such as cancers, congenital, and nervous system disorders.
Which country has the best genetics?
Data from Thomson Scientific’s Essential Science Indicators, 1 January 1997-31 October 2007
