Essays on DNA

The use of biometric identifiers in security systems is an enticing idea and has been embraced by the public following its use in banking systems where the data from iris scanners, facial recognition, and fingerprint scanners is utilized. Biometric identifier locates the user’s details from the central database, whereas the...

DNA Evidence and its Application in Forensic Investigations DNA evidence is among many scientific tools that have been provided for the investigation of forensic evidence via the analysis of DNA which is a material that makes up one's genetic code. DNA can be retrieved from their hair, blood, skin cells as...

CRISPR was first discovered by Ishino and coworkers at Osaka University in Japan while cloning a peculiar gene-repeat (Ishino et al. 5429-30). Nearly two decades later, a group of researchers at the food ingredient producer Danisco in Madison, United States, discovered that these CRISPR repetitions in bacteria offered defense against...

From its humble beginnings, forensic science has come a long way. For identification purposes, fingerprints have been used for a very long period. The breadth of forensic discoveries and advancements will be extended by this discipline. The tools used today to identify criminal offenders include DNA testing, impressions, and even...

Recently, it has been proposed that human DNA and RNA are structurally distinct. As the scientific theory of the origin and evolution of man indicates, the structure, a double helix, of these two salts, i.e., both the RNA and the DNA, has actually been present for billions of years. Numerous...

Introduction After the use of fingerprints, the use of DNA testing for forensic investigations can be considered the most important invention in the area of criminal investigations. The word "DNA" stands for deoxyribonucleic acid. DNA utilizes biological components like skin, hair, blood, and bodily fluids to identify people. A distinctive genetic...

The film Gattaca is set in the future, where DNA plays an important part in defining social class and genetic modification of people is common. Vincent, according to Brezina, Enrico, and Amelia, is born and conceived without the assistance of technology (338). Vincent is subjected to strong genetic prejudice and...

The jurors made a critical error in their evaluation of the evidence. With all of the evidence shown to the jurors, it is easy to conclude that there was no tampering with or framing of the evidence in order to frame "the kid" of the crime against his blood father....

The term "signature-tagged mutagenesis" (STM) refers to a technique that allows for the simultaneous screening of numerous different mutants. The method is accomplished by applying a special DNA sequence known as a signature tag to each of the implicated bacteria. Initially, this method was referred to as TN mutagenesis screening...

An organism classified as a genetically modified organism (GMO) has had its DNA altered or transformed. Recombinant DNA is a process that includes transferring genetic material from one plant or animal to another to create these organisms. The genetic engineering method produced GMOs (Zhang, 2016). The method involves inserting the...

DNA sequence changes can result from cell mutations passed down from a parent organism to its children. Some cell mutations can be advantageous, but the majority are damaging because they result in the cell's ability to perform a specific function being lost. Bacteria naturally experience base pair mutations at a...

Introduction Media, scientists, and governmental agencies have all expressed interest in and opinions about the use of genetic engineering and biotechnology. There are no definitive solutions to the question of what lies ahead for genetically engineered creatures. Organisms that have had their genetic makeup altered by genetic engineering are referred to...
