Gene duplication

Question 1. What were the main findings of the ENCODE project? Only a small percent of the 3.2 Gb human genome encodes for genes but much of the remainder was chalked up a junk. However, the ENCODE project suggests that up to 80% of the genome consist of various active regulatory, and structurally significant regions. Question 2. Define “junk DNA.” Junk DNA plays no active role in influencing an individual organism’s survival or reproduction, i.e. it does not code for or regulate…

Over the course of several millenniums, species have faced extinction by the hand of humans and nature. However, in recent decades, scientists have wondered if it is possible to bring back species that have gone extinct through genetics. Using DNA and protein coding, scientists have progressed to an era where what people thought was lost forever may just be capable of returning to a modern world. The ancestral genetic resurrection is composed of controversy in ethics, technological dependence,…

modification is adequately understandable with regardless of genes implantation that is also applied in most genetic engineered food products. However, human beings or plant modification of genes, such as boosting of muscles, implantation of growth, color of the eyes and hair, intelligent and stronger abilities could establish some serious effects on any livestock such as the inability to resist from any particular chronic disease. The modified gene can be implanted with a chip for which might…

Ethics of Cloning In The Creation: An Appeal to save life on earth, E.O. Wilson claims the next great extinction, in relation to mankind, is already in progress. If neglected, the extinction deems devastation to the degree of the final years of the Eremozoic Era. Wilson suggests that mankind takes a stand to either evolve alongside a quickly changing environment or change the whole environment around us by integrating genetic engineering (91). With this in mind, the twenty-first century has…

in the PER gene than the PER gene of diurnal animals. 2.) Differences in the sequences of PER genes can account for variance in the free running period (FRP) between varying organisms. 3.) Human PER gene homologs arose from prior duplication events throughout evolution. Motivation and Background: The biological clock is an endogenous mechanism that regulates the physiological activities of an organism. It was not until recently that much of the intricate molecular mechanisms or genes…

applied in many areas of DNA testing including analyses of deletion, mutations, and polymorphisms, or quantitative assays and reverse transcription (Henegariu et al., 1997). Indeed, this technique has several advantages such as increasing the number of genes that can be analyzed, reducing sample requirement, saving time, effort, and saving potentially money. Furthermore, using multiplex PCR, the same reaction conditions can be provided for several targets. This method can also provide internal…

Polyploidy refers to the individual with presence of more than two sets of chromosomes (3n, 4n, 5n, etc.) (Soltis et al., 2009) as sporophyte. Polyploids may have arisen as the result of nondisjunction during meiosis or may be generated when chromosomes are dividing properly in mitosis and meiosis, but the cytokinesis does not follow. Polyploidy can be classified into two: polysomic polyploidy (autopolyploidy) and disomic polyploidy (allopolyploidy) (Stebbins, 1951). Autopolyploidy comes from…

Information about an individual's ethnic background and parentage could become cause for discrimination; So Disadvantages include incomplete coverage, which can lead to false normal results, and the ability to test only for unbalanced rearrangements (duplications and deletions), and not balanced translocations or inversions. (Beldean Andreea…

human genes in a cell become abnormal and the cell starts to rapidly grow and divide out of control. Genes are pieces of DNA inside every individual cell that control and tell the cell what to do and when to grow and divide. Each gene is made up of a specific DNA sequence that contains the code to make a certain protein that contain a type of code that makes up certain proteins, in which each has a specific job or function in the human body. Each human cell contains around 25,000 different…

astonishing, we have similar genes. Many uninformed people assume that new genes and DNA are created for new species and structures; that statement is inaccurate. Our genes and DNA evolved over time, the proof…
