applications of molecular biology ppt

Once cDNA is synthesized, then a few hundred nucleotides (500-800bp) from either end (3’ or 5’ end) is sequenced to create two different kinds of ESTs. Background 3. RAPD markers are dominant in nature so it has restrictions for mapping purpose. BSc Biochemistry, BSc Medical Biochemistry, BSc Biological Sciences, BSc Human Biology; Level. The screening of microsatellite variation can be automated. The genotype of each individual is scored at hundreds or thousands of molecular marker loci (e.g.

  • Molecular biology allows the laboratory to be predictive in nature, it gives information that the patients may be at risk for disease (future). In the pool of unknown DNA or in a whole chromosome, these molecular markers helps in identification of particular sequence of DNA at particular location.

    This can be examined through the maternal line via sequencing their mitochondrial genome and through the paternal line via genotyping their Y-chromosome. Lastly, unlike visible traits such as eye color or petal color, the phenotype of a molecular marker can be detected in any tissue or developmental stage, and the same type of assay can be used to score molecular phenotypes at millions of different loci. It is based on PCR assay and it doesn’t need require any prior sequencing of DNA. The amplification of segment of DNA depends on the positions complimentary to the primers’ sequence. DIAGNOSTIC BIOMARKERS" program provides professional education and training at the post graduate level for laboratory scientists in the area of molecular diagnosis for acquired, inherited and infectious diseases. 2.

    CAPS marker was described by Konieczny and Ausubel in 1993 for genetic mapping. SCAR is based on PCR-agarose gel electrophoresis. For that reason, the many methods that are commonly used will first be described in details followed by lectures on how they can be applied in so different scientific disciplines.The Master's Degree program prepares professionals who will be competent in performing and interpreting molecular-based laboratory tests, explaining the appropriate use and meaning of molecular based tests to other professionals as well as to patients, establishing and validating new molecular methods in a molecular diagnosis laboratory.

    For example, markers can be identified by screening both the traits and molecular marker genotypes of hundreds of individuals. Molecular biology methods have tremendous value not only in the investigation of basic scientific questions, but also in application to a wide variety of problems affecting the overall human condition. For example, about 8% of the men in parts of Asia (about 0.5% of the men in the world) have a Y-chromosomal lineage belonging to Genghis Khan (the haplogroup C3) and his decendents.

Zabeau and Vos invented the AFLP technique in 1993. CAPS markers technique is based on the digestion of monomorphic PCR product for generation of polymorphism. If they don’t differ, then one can estimate the unlikelihood of them coming from different sources – eg they are from the same source. The products of digestion are screened for their differential migration rate in course of electrophoresis by staining with ethidium bromide. numerous physicists and chemists also took an interest in what would become molecular biology. Molecular Genetics and its Applications in Forensic Sciences. in 1985. Have questions or comments? Microsatellite consists of co-dominance of alleles and requires low quantities of DNA templates.
