DNA analysis has revolutionized crime-solving, transforming the landscape of forensic science by providing an unparalleled method for identifying suspects and exonerating the innocent. Through techniques such as DNA profiling and genetic fingerprinting, forensic experts can match biological samples from crime scenes—like blood, hair, or skin cells—to specific individuals with astonishing accuracy. This molecular approach has not only increased the rate of solving cold cases but also enhanced the precision of criminal investigations, ensuring that justice is served more reliably. Moreover, DNA databases have become invaluable resources, allowing law enforcement to cross-reference new evidence with existing records, thereby swiftly narrowing down suspects and generating leads. As technology advances, the scope and speed of DNA analysis continue to expand, promising even greater strides in the fight against crime and the pursuit of justice. #biotechfacts #biotechnology #microbiology #biotechnologist #biologylife #biotechlife #scientist #sciencestory #scientistlife ______________ Website: pawitrabiotech.com Instagram: @pawitrabiotech Email: info@pawitrabiotech.com  Linkedin: PT Pawitra Jaya Sakti Biotek Phone: +62 85 607 124 424

Kary B. Mullis: A lament for the loss of a life that saved many. An organism's genome is stored inside DNA molecules, but analyzing this genetic information requires quite a large amount of DNA. In 1985, Kary Mullis invented the process known as polymerase chain reaction (PCR), in which a small amount of DNA can be copied in large quantities over a short period of time. By applying heat, the DNA molecule's two strands are separated and the DNA building blocks that have been added are bonded to each strand. With the help of the enzyme DNA polymerase, new DNA chains are formed and the process can then be repeated. PCR has been of major importance in both medical research and forensic science. a technological leap forward that six years after Mullis discovered it in 1983 ushered in the DNA forensic age with the exoneration of Gary Dotson of the rape of Cathleen Crowell in Illinois. Crowell, 16, admitted faking the rape out of fear that her boyfriend had impregnated her. In 1993, PCR yielded its first exoneration in a death penalty case that of Kirk N. Bloodsworth, an ex-Marine with no criminal record, who had been convicted in 1985 of the rape and murder of a 9-year-old girl in Maryland. The conviction rested on the testimony of five eyewitnesses, whom PCR proved wrong. Kary received a Nobel Prize in chemistry in 1993, for his invention of the polymerase chain reaction (PCR). The process, which Kary Mullis conceptualized in 1983, is hailed as one of the monumental scientific techniques of the twentieth century. #karymullis #pcr

A paternity test using DNA is the legitimate method to identify a person’s biological father. It is a widely accepted method by law for clearing paternity disputes. These tests can be done with any biological material containing DNA, but preferably blood tests and swab tests are generally used. Technically this method can also able to determine the father of an unborn baby. #paternitytest #diagnostictests #biotechnology #science

In processes such as DNA fingerprinting based on different DNA base sequences scientists are able to perform crucial procedures such as forensic science common in crime investigations, partenity testing as well identifying individual. since DNA carries genetic information it's unique in every life form with exception of identical twins. #fascinating #biotechnologystudent #biotechnology #dnasequencing

The limitations of Streamlined Forensic Reports (#sfrs) are simple but also critical. Our forensic scientist (#biology) #expertwitness explains that the main limitation of SFR is that they were designed to streamline the investigative and charging processes. In fact, they were not intended for use in court.

The power (lessness) of 'peer reviewed' Lawyers beware The courts regularly hear experts say "peer reviewed paper" in support of opinions that don't hold water scientifically. This extract from a 2020 peer reviewed scientific paper, helps underscore the relative strength (or lack thereof) in making such broad and catch all "peer reviewed paper" claims; -------------- Samples from the fingers of the accused were submitted for mRNA and DNA profiling and the paper summarises the findings as follows: “Thanks to the use of the combined DNA profiling and RNA analysis it was possible to confirm the presence of the victim's genetic profile on the suspect's hand and to identify this biological material as vaginal secretion, confirming that the man had touched/penetrated the little child genital area." The issues - Transposed conditional - I.e., the probability of the activity. (science can't do this) Presumptive is not confirmatory - The testing used is known to give positive reactions to nasal mucous. ---------------- Most, if not all scientific papers have some utility to science and research (even when we learn what not to do), however we must stick to our lane in court. If we reference "peer reviewed paper" in court, we must do so with the paper in evidence and with a proper evaluation of that paper to the specifics of the matter itself.
