Abstract:
Technologies for genetic diagnosis are experimental techniques used to recognise and analyse the genes of an individual. Genes are segments of deoxyribonucleic acid (DNA) that bear a code for a specific protein that functions in the body in one or more cell types. Technology for genetic testing is rapidly developing. To replicate parts of a gene or find changes in genes, different methods can be used. It is a fact that these genetic diagnostic techniques become affordable for individuals to obtain accurate information about their genotype (the particular combination of genes or genetic makeup of a person) in the near future.

INTRODUCTION Technologies for genetic diagnosis are experimental techniques used to recognise and analyse the genes of an individual. Genes are segments of deoxyribonucleic acid (DNA) that bear a code for a specific protein that functions in the body in one or more cell types. Technology for genetic testing is rapidly developing. To replicate parts of a gene or find changes in genes, different methods can be used. It is a fact that these genetic diagnostic techniques become affordable for individuals to obtain accurate information about their genotype (the particular combination of genes or genetic makeup of a person) in the near future.

GENE PROBE: Proceeding faster into the field of Molecular Biology and clinical medicine, genetic diagnostic technology called gene probe can be generated in various ways and fall into three categories in general: oligonucleotide probe, polymorphic probes and gene-specific probes. The diagnostic tool can be utilized to locate a specific part of a gene (a segment of the gene’s DNA) or a whole gene in a particular chromosome. Probes can be used to find normal or mutated segments of DNA. A DNA segment that has been cloned or copied becomes a labelled probe when a radioactive atom or fluorescent dye is added to it. The probe will seek out its mirror-image segment of DNA and bind to it. Sophisticated microscopic and photographic techniques may then detect the labelled probe. A variety of diseases may be identified pre- and post-birth with gene probes. Gene probes will likely be used in the future to screen individuals concurrently for several significant genetic disorders.
