Scientists are constantly striving to make what was once thought of as impossible, possible. But, often in this race to break barriers, what holds back the scientific community is the ethical implications of their actions. With new gene-editing technology, such as CRISPR-Cas9 and TALENs, becoming well-known and easily accessible, genetic alterations are no longer an impossibility. The introduction of these methods presents untold opportunities for genome modification in plants, animals and even humans. However, while there are many positive applications...

Over the years genetic disorders and gene-related illness have been responsible for high mortality rates and reduced quality of life. Genetic disorders can be due to misalignment, missing genes or excess of a gene. Genetic therapy works to replace the defective genes with new ones. Gene therapy is the insertion of genes into an individual's cells and tissues to treat a disease, and hereditary diseases in which a defective mutant allele is replaced with a functional one. (Medlineplus 2020) Gene...

A genetic disorder is a disease caused by a mutation or change in an individual’s DNA. Sometimes a whole or part of a gene is defective or missing from birth or can mutate later in life, which can disrupt how proteins are made. This affects the body’s systems and causes health problems and diseases, such as sickle cell, SCID, and cancer. Majority of treatment strategies, for genetic disorders, do not alter the underlying genetic mutation, however a few have been...

Abstract CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) and CRISPR associated protein Cas9 has revolutionized gene and genome editing. This system was discovered in prokaryotes as a defence mechanism to protect themselves from viral predators via three basic steps of spacer-acquisition, Crispr RNA (crRNA) processing and interference. CRISPR-Cas display a prokaryotic adaptive immune system that memorize previous infection by integrating short sequence of invading genome-termed spacers. CRISPR-Cas9 has been developed into a simple, inexpensive and versatile tool for genome editing....

Gene cloning is a biotechnology in which a section of DNA is isolated and extracted before being cloned using bacterial plasmids. To execute this process, a restriction enzyme isolates a specific gene from a strand of DNA and the plasmid, and then cuts the gene creating complementary sticky or blunt ends. These are joined to form recombinant DNA, which is then inserted into bacteria via heat shock to be cloned. Gene cloning is used for many reasons such as to...

Abstract Amylase is an enzyme produced by the salivary glands and pancreas of Homo Sapiens to hydrolyse polysaccharides such as starch and glycogen (Tracey 2019). Variation in the number of AMY1A gene copies is thought to be a result of ancestral heritage and levels of consumed starch (Tracey 2019). Results from a previous study conclude there to be a positive correlation between the number of AMY1A gene repeats and salivary amylase protein expression (Perry et al. 2007). Given these findings,...

Enterotoxigenic Escherichia coli (ETEC) is one of six categories of pathogenic E. coli that can induce diarrhea in humans. The other five categories are enteropathogenic, enteroaggregative, enterohemorrhagic, enteroinvasive, and diffusely adhering E. coli. Out of all of these pathogenic categories of E. coli, ETEC is the most common cause of E. coli-mediated human diarrhea in the world (Turner, Scott-Tucker, Cooper, & Henderson, 2006). Annually, ETEC infections cause around 100,00 deaths (Crofts et al., 2018). The prototypical ETEC strain H10407 utilizes...

Gene therapy is the process through which healthy genetic code is included in cells to replace abnormal genes or create a desirable protein. Researchers explore various gene therapy strategies to resolve problems such as mutated gene replacement with a healthy gene code. This deactivates any mutated genes and adds a healthy gene into the body to help tackle a genetic disease. There are two possible mechanisms that could be used to undertake gene therapy: Somatic and germline gene therapy. The...

Introduction Gene therapy typically involves the insertion of a functioning gene into cells to correct a cellular dysfunction or to provide a new cellular function. For example, diseases such as cystic fibrosis, combined immune deficiency syndromes, muscular dystrophy, hemophilia, and many cancers result from the presence of defective genes [1]. Gene therapy is basically to correct defective genes responsible for genetic disorder either by insertion (most common), homologous recombination, through selective reverse mutation, or by altering the regulation of a...

Gene editing and enhancing, which allows for a particular area in the genome to end up being targeted and changed by deleting, substituting or adding nucleotides, is currently the subject matter of very much academics, policy, and industry discussions. While not really fresh per se, gene editing has become a particularly salient topic mainly due to a relatively novel tool called CRISPR-Cas9. This particular device distinguishes itself from its counterparts, (at the.g., zinc-finger nucleases and TAL effector nucleases (TALENs)) credited...
