Aquatic Genes In Tibetans

Improved Essays
Certain groups of people work very well at high altitudes. People who live at higher altitudes are expected to have a higher hemoglobin count since hemoglobin helps deliver oxygen to tissues. The amount of oxygen in the atmosphere decreases as the altitude increases. The increase in hemoglobin helps blood cells carry more oxygen to nourish the body. This is true with the majority of people who live in these regions such as in the Andes, Rockies, and the Alps. There is a group of people from Tibet who does not follow this concept. They have a much lower hemoglobin level than an average person. They live and work just as successfully as other groups in higher altitudes. Scientists questioned why did the Tibetans have a lower hemoglobin count …show more content…
To extract the DNA samples, we will ask 50 males and 50 females for a total of 100 voluntary Tibetans who are 18 and older from the same region to give a small sample of blood. The blood samples contain DNA and genes that we will use to analyze to find the EPAS1-TD gene. In order to analyze the genes from the blood samples, we need to perform the procedure of PCR, polymerase chain reaction, to amplify and clone the DNA. Performing PCR is necessary because it allows us to amplify a particular region of the DNA, the EPAS1 gene, set up by the primers in the annealing process. This is very quick and efficient for cloning the EPAS1 gene. After getting the PCR product containing the EPAS1-TD gene, we need to clean the PCR product through column chromatography. This will dissolve all the contaminants such as the excess primers and NTPS which will preserve our DNA specimen. To put the gene into the plasmid PGEM3Z, we will digest the DNA by using restriction enzymes such as Xba I to cut the DNA into smaller fragments containing the EPAS1-TD gene. The restriction enzymes will also cut at the designated restriction enzyme cleavage site in the plasmid where it will transfer the cut up EPAS1 gene into the plasmid PGEM3Z. The DNA Ligase will come and seal the plasmid shut with the EPAS1 gene DNA segment in it. Doing this will allow for the control of gene

(Khan Academy) E. coli chooses prefers glucose and other "better" sugars, so if any are present other than lactose the lac operon will not be expressed in the plasmid.

    Identifying an Unknown Plasmid Through the Process of Gel Electrophoresis Introduction: Biotechnology requires certain techniques and methods that help identify plasmids, which can be used for forensics, DNA fingerprinting, etc. In this class, each lab focused on teaching the process of using the correct techniques used to identify a plasmid. Plasmids are pieces of DNA that are circular and relatively smaller than chromosomes. They aren’t important in the sense that they don’t carry out critical functions required for growth and life. Also, they are located in the cytoplasm, outside of the chromosome and nucleus of a cell.…

    Several Advancements in technology produced a fast DNA sequencer in the 70’s, and in 1983, Karv Mullis created what is called Polymerase Chain Reaction (PCR). PCR is a very simple and inexpensive technology that is used to amplify and produce large amounts of copies of a segment of DNA. Now this has become one of the most significant scientific advances in molecular biology, PCR amplification is used every day to diagnose diseases, its also used to identify bacteria and viruses, and to match criminals to crime scenes. PCR has revolutionized the study of DNA to such an extent that Dr. Mullis was awarded the Nobel Prize in Chemistry in 1993.…

    Sickle cell anemia is a disease that results in the destruction of the protein hemoglobin. Hemoglobin is a molecule located in the red blood cells that is responsible for the delivery of oxygen to the cells to the entire human body. This disease is a reaction of a point mutation in the β-hemoglobin gene that leads to the synthesis of sickle hemoglobin, which distorts and injures the red blood cell (Solovieff, Hartley, Baldwin, Klings, Gladwin, Taylor, & Sebastiani, 2011). Healthy red blood cells are round and able to maneuver throughout the body very easily if they contain hemoglobin A, which is the desired protein. Unlike normal red blood cells, patients with sickle cell anemia develop a “sickle cell” shape, making the red blood cells incompetent…

    Life, from its origin 4 billion years ago to the present, is ever changing due to the differential success of various evolutionary lineages and genes. Our understanding of these changes, and our ability to influence them, has been revolutionized in recent years, mostly due to technological advances. Surprisingly, genomes are far more fluid than once believed. Furthermore, recent discoveries have enabled us to directly engineer genomes, including human genomes and those of other species. These developments are likely to have wide applications in the future and to affect all of our lives.…

    Research for Sickle Cell Disease started in 1910.When a patient from the West Indies had anemia characterized by oddly shaped red blood cells. A Chicago physician, James B. Herrick identified the red blood cells as sickled shaped. It was discovered that the sickling of the cells was associated with the low oxygen in 1927 by Hahn and Gillespie. A medical student at John Hopkins, Sherman, noticed the birefringence of deoxygenated red blood cells, recommended that low oxygen adjusted the hemoglobin structure in the molecule. In 1948 multiple individuals made discoveries.…

    Protein mutations are often introduced at the DNA level in the corresponding gene, which takes advantage of the central dogma of biology (DNA is transcribed to mRNA; mRNA is translated to proteins. The introduction of mutations in target genes has become trivial with the advances in synthetic biology. Major classes of library construction include (1) random mutagenesis, (2) recombination, (3) semi-rational design, and (4) scanning mutagenesis. Together, these classes of library construction are termed “combinatorial design” and require little to no prior knowledge of the protein, albeit more knowledge can help design libraries more efficiently. The counter technique is termed “rational design” and requires detailed information about the…
