Genome editing involves the modification of the genome at a specific site in a DNA sequence [1]. Today, genetic engineering is used in overcoming many single-gene ailments such as cystic fibrosis, haemophilia, and a plethora of other diseases. However it was not until 2012, that the genome editing technique known as the Clustered Regularly Interspaced … Read more
Should we do it? Would it make us a ‘better’ species? In a world of advancing technology, we suddenly have the power to edit our DNA like a word processor; we could potentially eliminate the chances of inherited diseases altogether which would ultimately save countless lives. However, this may open a door to creating genetically … Read more
Chinese scientist, He Jiankui, has created the first genetically modified human babies through the controversial process of gene editing. The process of Gene editing functions by changing a person’s DNA. Jiankui’s conduction of this on unborn children is under fire by some (including his country’s government) and supported by others. Many scientists around the world … Read more
Imagine a world where you are able to alter the life of your unborn child for as little as $160. Would you do it? Most parents would. Many think that this question won’t be posed for hundreds of years, but in reality, this modification already occurs and only stands to grow within the coming decades. … Read more
Refraction of light results from the phase shift of wavefront points, as their velocity changes within media of different optical properties. Snell’s law (the law of refraction) is a formula used to describe the relationship between the angles of incidence and refraction, when referring to light or other waves passing through a boundary between two … Read more
Introduction The scientific abilities gene editing can provide are vastly beneficial, yet have sparked debate about its efficacy. With this power there have been many debates whether it should be illegal or not. Some feel that this is immoral, while others argue that the scientific benefit it can provide outweigh the fact it causes ethical … Read more
Section 1 – Summary Study: Zhong, G., Wang, H., Li, Y., Tran, M. H., & Farzan, M. (2017, June 19). Cpf1 proteins excise CRISPR RNAs from mRNA transcripts in mammalian cells. Scientists at The Scripps Research Institute (TSRI), in Florida, discovered a way to further optimize gene-editing technology. The scientists at TSRI were able to … Read more
Though the ethical concerns of gene editing and similar practices have existed since the concept first emerged decades ago, new discussions have arisen with the CRISPR-Cas9 technique. CRISPR-Cas9 is used to cut DNA at a particular, targeted location. The complex made up of Cas9 and guide RNA can find a targeted section and cut it. … Read more
The latest genomic engineering tool used in science, CRISPR/Cas9 has been used in many studies. Research proves that it is efficient at crop improvement and helps prevent the spread of diseases. However, research exists that allow gene editing to be even more efficient with the use of multiple gRNAs (guide RNA). This review focuses on … Read more
Partial acquired genetic resistance to HIV after targeted gene disruption (infusion of autologous CD4 T cells modified at CCR5 by a ZFN).
The science of hereditary has changed hugely since the first experiments done by Mendel in his pea garden. What he discovered then was the existence and fundamental importance of the gene and its function in inheritance, predicting the patterns of behaviour during the formation of gametes. Although there was no knowledge at the time of … Read more
This essay considers the biological/social implications of Gene Drives and whether New Zealand should change their regulations to permit them.
This essay concludes that the benefits of allowing GMOs to be planted outweighs any biological risks or possible negative economic impacts.
Implications are defined as “the conclusion that can be drawn from something although it is not explicitly stated”, or “inferred”. The nature of something refers to “the inherent and unchangeable character”. In the context of the Grain-Fed Beef Industry, it’s inherent characteristics are that it is a world-wide, ever-expanding economic activity where high value food … Read more
This essay looks at the development of the Crispr Cas9 system and what it can do, together with previous techniques used before CRISPR.
