Construction of DNA, RNA, And Protein By Building Models Introduction Nucleic acids are made of nucleotides. When these nucleic acids form sequences they create either DNA or RNA. DNA and RNA are composed of a phosphate, a sugar, and a nitrogen base. The main difference in RNA and DNA is that uracil replaces the base of thymine in RNA. Proteins are essential to maintaining cells by creating hormones and enzymes, and defending the cell. The arrangement of DNA and RNA bases dictates what protein…

based DNA isolation, DNA was isolated from buccal cells to study the genes TAS2R38, CDK3, ADH/ALDH, and D1S80. It was hypothesized that after gel electrophoresis, the TAS2R38 DNA sample will be cleaved at two places, since by the taste test was positive for PAV. The CDK3 gene will display one or two bands and the ADH/ALDH was expected to form one or three bands based on homozygosity or heterozygosity for the gene. D1S80 will have repeated sequences from 14 to 72 repeats. After examining the DNA…

The result from the transformation process showed no colony growth on the agar plate, which means no plasmid DNA got inserted into the vector (Table 1). Thus, the transformation was considered unsuccessful. With that being said, the gene was not transferred among the bacterial cells. The reason could have been that the agar plate had a strong concentration of antimicrobial drug, so the bacteria may have been unable to grow under such condition. Another reason could be that the cell did not get…

Introduction: The United States has been passing around the idea of a national DNA database much controversy has stemmed from this issue. This issue offers many benefits such as disaster identification, catching criminals and helping medical staff with the inclusion of medical records. On the other hand many view this as a blatant disregard for people’s privacy and a threat to their democracy. It is seen as a system that is much to costly and easily abused and too totalitarian for the government…

Significant quantities of DNA can be extracted from the coronal and root portions of tooth, including the root tips. However, the root body is the region that yields maximum quantitiy of DNA. The quality and quantity of DNA extracted from teeth provides a great advantage in forensic DNA analysis. [10] Teeth is divided into two parts anatomically: i) The crown - which is exposed in the mouth and ii) The roots which are enclosed in the alveolar bone of the jaws. Tooth roots which are composed…

Science, “In April of 1953 Watson and Crick published a model of the DNA helix in a one page letter to Nature. It began with the now famous understatement: ‘We wish to suggest a structure for the salt of deoxyribose nucleic acid (D.N.A.). This structure has novel features which are of considerable biological interest’” (Laboratory. 2011). This is the very foundation that DNA was discovered. According to Forensic Magazine, “DNA profiling was originally developed as a method of determining…

bring a lot of DNA and proteins into the water. By testing water samples from various parts of Lake Elsinore, for quality of DNA and protein, one can determine where the highest concentration of life exists. What is DNA? DNA stands for deoxyribonucleic acid. DNA is in all living things. Most cells in the human body have the same DNA inside of their cells. Most DNA is at the nucleus of a cell. Mitochondria are a part of a cell (“What is DNA?”). DNA is also found in mitochondria. The DNA inside…

Describe the chemical structure and function of DNA DNA is a fundamental molecule responsible for the growth and maintenance of the human body. Since the discovery of DNA and its double helix structure though the Watson-Crick Model, there has been a significant increase in the understanding of human disease and development of effective treatment. DNA’s specific chemical structure allows it to carry out its function which therefore maintains our survival. Deoxyribonucleic acid is a…

Today in lab we worked/talked about DNA. DNA is molecules called nucleotides. What is the main purpose of DNA ? The main role of DNA in the cell is the long-term storage of information. Where is the DNA found in the body ? Most DNA is located in the cell nucleus. Okay so in lab, we did an experience. We used A Heavy duty ziploc bag, 1 strawberry [including the stem], 10 mL DNA extractions buffer [ soapy, salty water], Cheesecloth, Funnel, 50mL vial/ test tube, Glass rod, Inoculating loop, or…

DNA stands for deoxyribonucleic acid and it is a self cloning material present in nearly all living beings. The DNA carries all the genetic information of that specific being. Humans and animal DNA was discovered to be very similar, so scientist questions what they could do with that information. In the article “ Will gene-altered athletes kill sports? Soon animal DNA could make us faster and stronger.no training needed” by Gregory M. Lamb, he wrote about how scientists are mixing human DNA with…
