Essays on Crispr

Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) are prearranged sections in bacterial as well as archaeal genomes, which form part of an adaptive immune system against phages —viruses that infect bacteria but not humans. CRISPR and CRISPR-associated (Cas) systems have been rapidly emerging as an alternative genomic editing tool to ZFNs (zinc-fingernuclease) and TALENs (Transcription activator-like effector nucleases). In the article, “Targeted mutagenesis in rice using CRISPR-Cas system,” the author applies CRISPR/Cas system in rice (Miao, et al.). The author investigates whether the CRISPR/Cas technology can create double standard breaks (DSB) in rice callus. The successful application of CRISPR/Cas ...

The development of CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) technology has transformed genetics and gene editing. CRISPR’s precision and efficiency have allowed scientists to control and modify genetic material with unparalleled precision. This technology, however, presents a slew of ethical issues about its possible ramifications and implications. This essay will outline the CRISPR technology, discuss the ethical problems with CRISPR and conflicts surrounding it, as well as argue whether gene editing is ethical in general.

What Is the CRISPR Technology?

CRISPR technology is a genetic technique that allows researchers to alter particular genes in an organism’s DNA. The method employs a class of enzymes ...

1. A brief summary of the article The article “Gene editing technique could transform future” by Fergus Walsh, which appears in BBC news, discusses the advancements made by genetic engineering in the realm of gene splicing and manipulation. The CRISPR technology allows scientists to produce clearly defined results when attempting to make changes at the genetic level. One important concept that arises from this technical development is the ability to alter or repair damaged DNA. This could have profound implications for health and medicine, which has led genetic engineers to pursue it to a greater degree. However, Walsh indicates ...

Introduction

The treatment for multitudes of diseases and disorders resulting from genetic reasons have been ambiguous since long as the only cure could be the correction of genes and DNA in the specific region. Gene therapy gave a promising horizon to the correction of such genetic defects whereby molecular tools are applied to reverse the mutation or any other changes in the DNA. The advancing biomedical research have offered several tools for gene therapy since last few decades that have been able to perform the desired roles but with one or the other limitations. Lately, CRISPR-Cas9 based tools for gene ...

Introduction

Scientists have discovered a way of turning off genes so as to provide room for studying how cells work and other aspects of the cells. The discovery has been deemed to be a major success towards a news technology in studying the biochemical pathways and interactions that occur in cells hence facilitating normal development as well as disease progression. Norris (Para. 1) points out that, scientists at UC San Francisco have made this major breakthrough of turning off genes in cells. They indicate that the ability to turn off genes will pave way to increase in research and making of discoveries in ...
