Table of ContentsIntroductionUsing DNA ExtractionConclusionIntroductionDNA are molecules found in chromosomes that contain your genetic information. Every human has a different set of DNA. The first to study DNA was the Swiss chemist Johann Friedrich Miescher, in the 1860s. Some of the famous pioneers who contributed to the study and research of DNA were James Watson, Francis Crick and Rosalind Franklin. Say no to plagiarism.

We are now able to perform forensic testing, diagnostic testing, carrier testing and paternity testing. One of the most well-known methods used to perform these tests is DNA extraction. DNA extraction is the process by which DNA is separated from the cellular material contained in the acquired cell. Although this process is extremely useful in genetic research and forensic testing, it is a very critical and labor-intensive process. People handling DNA must be careful to avoid contamination or cross-referencing of the DNA sample. To extract the DNA, the sample is placed in a test tube with lysis buffer, intended to break down the cell membrane. The lysis buffer is then washed and substances that disrupt the cell's proteins and RNA (ribonucleic acid), such as protease and RNAse, are then placed in a container with the sample. The sample is then cleaned, captured and ready for extraction. Once the extraction solution is added to the cells, it is placed in an incubator overnight, undisturbed. After that, the extract is harvested. Use of DNA Extraction DNA extraction has many uses. One of these uses is in the genetic modification of plants. Genetic engineers can remove or add traits to the plant, such as pesticide resistance or a change in size. Many agricultural companies use it to increase their production. DNA extract. Then they clone the genes they need and use them in other plants. The pharmaceutical industry also uses DNA. This is usually the first step in the development of various types of drugs. The hepatitis B vaccine is an example. Forensic testing involves using each person's unique DNA to identify the culprit of a crime from a group of suspects. This type of testing has helped enforce the law and achieve justice. DNA is found in all parts of the body such as strands of hair, blood, sweat, saliva..etc. This evidence is found on the weapons used in the crimes, on the furniture during the crime, on the clothing the suspect was wearing, and more. This makes forensic DNA testing very practical. Forensic scientists collect DNA from the crime scene and work to find an identical match. Forensic DNA testing was first used in 1985 in England, when a 17-year-old boy was accused of murdering and raping two women in his neighborhood. DNA testing revealed that the young boy was actually innocent and helped police arrest the real criminal. DNA paternity tests are used to confirm a baby's biological parents or any biological relationship (e.g. siblings, aunts, grandparents, cousins). . Given that.
