Noncoding DNA

The video Will Our Kids be a Different Species by Juan Enriquez raises a variety of questions about the human genome and where future generations are heading. During the first few minutes of the video Enriquez introduces the expansion of the universe. He explains the formation of the galaxy, Earth, and life. He then introduces the process of genome mapping and how different genes are being discovered that might show humans are different. He explains how it is now possible to recreate organisms…

Introduction: In this lab experimentation, the group conducted Deoxyribonucleic acid isolation and restriction analysis on a plasmid from Escherichia coli cells. Plasmids are small circular DNA that are in the bacterium cells. Escherichia coli is a gram- negative bacterium that is known for variable reaction to antibiotics, and can be genetically manipulated. The gram- negative bacterium, Escherichia coli can be genetically manipulated by extracting a certain plasmid that allows it to resist…

Transforming Genetic Material To E. Coli Using Plasmids Proteins are created within the body through a process known as central dogma. This process is the transcription of DNA to RNA and the translation of RNA to proteins. The type of protein created relies on what type of messenger RNA or mRNA that was produced during the transcription of DNA. In our experiment, we looked at the specific LacZ gene that codes for beta-galactosidase, which is a protein/enzyme that can break down lactose into its…

What are genetically modified organisms? Genetically modified organisms (GMOs) are living organisms whose genetic material has been artificially manipulated in a laboratory through genetic engineering. Throughout the United States, the majority of the crops have been totally modified with genetic engineering. Lots of food we eat today is now genetically modified, and we do not really know if what we are eating is natural or non-natural. This has made a great impact in American agricultural world…

Bacteria often contain plasmids, plasmids are circular, double stranded DNA that is not part of the nuclear DNA. Plasmids usually contain genes that code for several traits. Genetic transformation relies on inserting a gene that codes for a new trait in to the plasmid. For this lab, genetic transformation is the insertion of a new DNA in to E.coli cells, the pGLO plasmid was genetically engineered to carry the green fluorescent protein and a gene that codes for a protein that gives the bacteria…

The certain mutations required for detection, signaling, and repair of DNA damage can actually lead to more DNA damage, the incorrect repair of damage, and cancer. If DNA repair pathways that are needed for the life and growth of a tumor can be found and delayed, then the use of chemotherapy and radiotherapy can and will be much more successful (Bolderson, Richard, Zhou…

The increase of knowledge regarding the topic altering genes has become rapid and have open and paved the hope of designing your own perfect baby. Even today, the use of reforming and adjusting the genes of an unborn child is being put in effect. “Techniques of genetic screening are already being used, whereby embryos can be selected by sex and checked for certain disease-bearing genes. This can lead to either the termination of a pregnancy, or if analyzed at a pre-implantation stage when using…

Primate Taxonomy Primate Taxonomy Introduction This first lecture is designed to introduce the primate order in terms of its classification and to familiarise you with the animals so that the rest of the course makes some sort of sense. I will cover a working definition of what makes a primate, give you a general classification scheme, describe the major features that identify the groups within the classification and discuss some of the controversial areas of the classification. I shall…
