Last Will may prevail over earlier Will:-

  Last Will may prevail over earlier Will:- In case of dispute between earlier and subsequent parts of a Will,the subsequent part of the Will will prevails ( Kaivelikkal Ambunhi & ors vs H.Ganesh Bhandary,(1995) 5 SCC-444 & Uma Devi Nambiar & ors vs TC Sidhan,( 2004) 2 SCC-321. In case of “ Jasbir Singh vs Jaspal Singh & ors ”,2016 SCC Online P & H-3416,it   was held that the last will would prevail and the previous Will automatically deemed to have been cancelled, even in the absence of any specific clause.

Scientific and Legal Dimensions of DNA Technology

            DNA fingerprinting, profiling, or typing is widely considered the most significant contribution of science and technology in the twentieth century. This breakthrough is anticipated to become the universal identification technique of the twenty-first century. This emerging methodology has completely revolutionized the entire world by distinguishing every individual from another. Consequently, it plays a momentous role in both criminal and civil justice delivery systems today. It serves as an invaluable tool for the accurate identification of ancient or fragmented skeletal remains. Medical professionals also rely heavily on this technology for the detection of early onset diseases. Furthermore, it allows for the proactive mapping and diagnosis of various severe inherited disorders. This high-utility identification power stems directly from the biological blueprint found within living organisms.

            Deoxyribonucleic acid, commonly known as DNA, is the complex chemical structure that uniquely identifies each organism. An organism’s complete set of genetic material is known scientifically as its genome. This unique chemical compound acts as the fundamental building block of the entire genome. Structurally, DNA molecules are located securely inside an organism’s microscopic cellular chromosomes. A chromosome is a specialized structure found directly within the central cell nucleus. These structures contain genes, which function as the physical units of heredity passed across generations. Chromosomes themselves are composed of dense chains of DNA wrapped tightly around protective proteins. Each biological parent contributes exactly one chromosome to each pair of a child's chromosomes. Therefore, children inherit half of their genetic chromosomes from their mothers and half from their fathers.

            Every living organism is made up of individual cells that encompass these hereditary chromosomes. These nuclear chromosomes harbor our unique DNA strands like an organized biological database. The specific, fixed position on a chromosome where a particular gene is located is known as a locus. This designated chromosomal locus is what contains the stretch of DNA targeted during forensic evaluation. Forensic scientists analyze this specific locus to observe and document genetic variability between individuals. To extract these profiles, scientists rely almost exclusively on two primary laboratory methodologies. The first major technique is known as restriction fragment length polymorphism, or RFLP. The second dominant method involves polymerase chain reaction, which amplifies short tandem repeats. While alternative genetic testing methods exist, they generally lack the required technical precision. Ultimately, RFLP and PCR stand as the only globally accepted standards for absolute forensic accuracy.
