Jakarta – Former Governor of West Java (West Java) Ridwan Kamil (RC), Lisa Mariana, and the initials CA underwent DNA tests at the Criminal Investigation Police, South Jakarta (South Jakarta). This investigation was conducted to determine who the biological father of the child ca. The DNA test series begins with blood sampling and saliva of RK, Lisa Mariana, and children ca. The sampling was conducted by the National Police Pusdokkes team on Thursday, August 7, 2025 after the parties signed a letter for medical action. DNA tests are scientific methods that are often used in legal processes and biological identification. In this case, investigation becomes an important stage because it prioritizes objective genetic evidence, not just oral information. Browse to continue with the content quoted from MedlinePlus, deoxyribonucleic acid of DNA is a genetic material that carries instructions to form and regulate the function of each living being. In other words, DNA is a ‘unique code’ that determines a variety of physical and biological properties of a person. Everyone has a different arrangement of DNA except for identical twins. DNA is inherited from parents to children, which therefore contains genetic information from both parties. DNA test is a scientific investigation that compares the arrangement of DNA of two or more people to see if there is certain compatibility. According to MedlinePlus, this test is still used for different purposes, ranging from the examination of family relationships (eg paternity tests), which helps the diagnosis of genetic diseases to individual identification in legal or forensic cases. DNA test results are very accurate because they rely on unique genetic markers in everyone. Conditions and procedures for DNA tests are cited by Antara News Agency. DNA tests cannot be done randomly. Although there are no specific requirements for anyone to live it out, this investigation is mostly conducted by individuals who have certain interests, both for medical, legal or personal purposes. Generally, the DNA test procedure includes: Biological sample sampling is collected from people examined, such as blood, hair, skin, saliva or pieces of nails. For family relationship tests, samples are taken from those compared, such as Father and Son. DNA extraction samples are processed to separate DNA from other components, usually using special enzymes. DNA -electrophoresis extracted is separated in fragments based on its size using an electric field. Polymerase Chain Reaction (PCR) DNA is selectively reproduced, so there are quite many copies that need to be analyzed. DNA analysis reproduced is analyzed to find certain genetic markers adapted to the purpose of the investigation. Comparing DNA If the test is aimed at testing family relationships, DNA results are compared to the view of compatibility, for example in the paternity test, half the composition of the child’s DNA will match the father’s DNA. The results and waiting time of the test results usually come out within 2-4 weeks or longer, depending on the complexity of the investigation. (Wia/Zap)
