Case study is the study of a court case which helps us to get an insight into the real life proceeding of the theoretical knowledge of something that we have. With respect to forensic science, we can say that case study helps us to get an idea of the principles and techniques that are applied in a real case in order to obtain the results. It also helps us to understand what might be the outcome of a particular approach in terms of the legal system in a specific type of case that is looked into. Here the case of child custody with the help of DNA fingerprinting is to be analysed and considered to help us understand how DNA fingerprinting might play a vital role in proving the parents of a child in a court case.

Genetic information is contained in chromosomes of humans. Each human has 23 pairs of chromosomes in their bodies. Among them, each part of the pair is obtained from one of the parents. Genetic information is inheritable, that is, they are passed on from parents to their offspring. DNA is contained in the chromosome and is present in the nucleus of cells of human body. DNA consists of nucleotides like adenine, guanine, cytosine and thymine. In each case, adenine pairs up with thymine and guanine pairs up with cytosine to form the DNA backbone. Now in each DNA the sequence in which these nucleotides are present is what distinguishes one individual from another and is unique to everyone. It is therefore to be noted that this DNA sequence serves as an identity or fingerprint for every individual. This is the basis on which the method of DNA fingerprinting analysis is conducted. The DNA constitution of all cells present in an individual are the same and it does not change with the passage of time. Also, unlike normal fingerprinting, DNA fingerprinting of an individual cannot be altered surgically. The only exception for the uniqueness of DNA fingerprint is the case of identical twins or triplets. The chances that the DNA fingerprint found at a crime scene might be duplicated are roughly 1 in
