Genteknologi og celleteknologi

Det europæiske forår er et dystopisk billede af Europas fremtid. Vi følger fire mennesker i begyndelsen af et nyt årtusinde. Lolland er blevet opkøbt af et internationalt konsortium, og nu skal øen omdannes til et økologisk drømmeland, hvor rige mennesker kan nyde lokale råvarer og en smuk – og slet ikke så naturlig – natur. For at bevare idyllen i Europa sætter danskerne hårdt ind over for terror, og med militærets hjælp deporteres samtlige urostiftere og utilpassede med muslimsk baggrund til en containerby i Mozambique. Forfatteren eksperimenterer med grænserne for, hvad man kan tillade sig i kunstens navn og med etikkens sande væsen. Idealer, udnyttelse og realitet går hånd i hånd i denne tankevækkende roman, som tvinger læseren til at forholde sig til store dilemmaer, som trods deres fiktive afsæt slet ikke føles langt væk fra den verden, vi lever i.

Document from the year 2020 in the subject Biology - Genetics / Gene Technology, grade: PhD student, Southwest University, language: English, abstract: This book systematically introduces the basic knowledge of the Hypothalamic Pituitary Gonads (HPG) axis and provides information on the location and regulation, gene mutations, function, reproduction, life cycle, sexual behaviour, disorders and the role of the environmental factors on GnRH gene. Also, we focused on gene and receptor structures, and the signalling pathways of GnRH, and its related genes and hormones such as Luteinizing Hormone (LH), Follicle-Stimulating Hormone (FSH), Progesterone (P4) and Oestradiol (E2). Also, it was pointed to Gonadotropin Inhibiting Hormone (GnIH) and its related peptides, such as RFamide peptides which were found to decrease hormones secretion by working on HPG in an inhibiting biosynthesis process of gonadotropin (¿¿¿) subunits. In addition, the roles of hormones on fertility and reproduction, also, disruption resulted from mutations. Special characteristics of many hormones and pulsatile secretions of GnRH were summarized.This information is necessary for an understanding way of work some necessary hormones also, elucidating reasons infertility. Although, several studies have presented a lot of kinds of regulators of expression for many genes related by fertility in many species, however, the knowledge of the relationship between molecular relating and infertility still has many gaps and problematic, also, many remains to be discovered, and a lot of significant questions (such as sexual behaviour, the regulation of gonadotropin secretion, and growth of tumour cell, in addition to; whether GnRHs are expressed as a full-length or not?), need to be solved, and mechanisms of pulsatile secretions and potential functions of many reproductive hormones need to be elucidated. So, this investigation very important for those researchers and readers to start solve and answer these questions and understanding many things related to (HPG) axis, and (GnRH).

In this Very Short Introduction to the gene Jonathan Slack explores the discovery, nature, and role of genes in evolution and development. Looking at how genes are understood as a concept, the nature of genetic variation, and how their mutation can lead to disease, this is an ideal guide for anyone curious about what genes are and how they work.

Combining elements of biochemistry, molecular biology, and immunology, artificial DNA can be employed in a number of scientific disciplines. Some of the varied applications include site-specific mutagenesis, hybridization, amplification, protein engineering, anti-sense technology, DNA vaccines, protein vaccines, recombinant antibodies, screening for genetic and pathogenic diseases, development of materials with new biochemical and structural properties, and many more. Artificial DNA: Methods and Applications introduces the concept of artificial DNA that has been rationally designed and explains how it may be exploited in order to develop products that will achieve your intended purpose. The first part of the book covers methods of oligonucleotide synthesis and direct applications of synthetic DNA. The second part describes methods of gene assembly from synthetic oligonucleotides and applications of synthetic genes. The authors also discuss the different trends and future developments within each application area .With state-of-the art research, the contributing authors describe how to engineer proteins using rational and semi-rational design to exhibit the desired traits and detail the various amplification reactions and hybridization techniques for modeling evolution and for use in basic research. The only text devoted to this subject, Artificial DNA offers a comprehensive review that allows you to understand the strategy, design, and applications of synthetic oligonucleotides.

In 14 essays by Australian and New Zealand writers critiquing the new biology, and with a foreword by Mae-Wan Ho (the UK scientist leading a global attack on genetic engineering as 'bad science') 'Recoding Nature' challenges the assumptions of those preparing the world for a 'recoded' DNA future.
