DNA analyzing has been playing an increasingly role in the medical field. Genetic diseases’ rate is progressively growing but with the new technology‚ doctors are able now to reduce that high rate by using new invention. For example‚ with DNA analyzing doctors have the ability to reorganize the genetic disorder to make it better. Furthermore‚ now they can catalyze human body’s cells to produce a healing or therapeutic substance that could control the disease instead of fighting it. In another point

Discovery of DNA Erwin Chargaff: Chargaff was an Austrian biochemist‚ he was best known for “Chargaff’s Rules” which lead to the discovery of DNA’s double helix structure. He immigrated to New York and secured a position as a research associate in the biochemistry department at Columbia University. Became a full-fledged professor in 1952. He used chromatographic techniques in his research. It was in the U.S.‚ 1950’s where he was able to make the crucial elements‚ in which lead to the formation

3.1 Source of the Recombinant DNA Polymerase SK72 The recombinant E. coli BL21 (DE3) containing the pET 32b/ DNA polymerase SK72 gene was provided by the Laboratory of Enzyme and Microbial Technology‚ Institute of Bioscience‚ Universiti Putra Malaysia. 3.2 Preparation of the Lysogeny Broth (LB) Agar Plates LB agar plates were prepared by dissolving 10g tryptone‚ 5g yeast extract‚ 5g NaCl and 15g bacterial agar in 950mL of deionized water. The pH of the medium was adjusted to 7.5 using 1M NaOH before

Can you expect to extract more DNA from a strawberry or kiwi fruit? Introduction: In the experiment we were inspecting the amount of genetic materials in fruits with different numbers of chromosomes. In the experiment‚ we mashed up a strawberry/kiwi fruit (See appendix 1 figure 2) added extraction butter and ethanol to extract the DNA. A chromosome is a long thread-like cluster of genes in the nucleus. DNA (deoxyribonucleic acid)‚ a self-replicating material which is present in nearly all living

With a new study on evolution‚ scientists have discovered that the mitochondrial genomes of birds have found two mutations within the mitochondrial genomes within fifty years. Within those fifty years it has shown two mutations within the mitochondrial genomes which can debunk the two percent of evolution per million years. By studying individual chickens Professor Greger Larson at Oxford University’s Research Laboratory for Archaeology‚ they have found two mutations in the mitochondrial genomes

Biochemical Prospective of DNA polymerase in Replication Biologists and chemists have long recognized a relationship among DNA‚ RNA‚ and protein‚ and this recognition has guided a vast amount of research over the past decades and generations. The pathway of DNA to RNA and RNA to protein is conserved in all forms of life and is often called the Central Dogma. DNA functions as a storage molecule‚ holding genetic information for the lifetime of a cellular organism‚ and allowing that information

INTRODUCTION: NULL HYPOTHEISIS: Mental disorders are not present in animals. HYPOTHESIS: As much as life has evolved‚ the relationship between animals and humans has remained very close to each other. If animals are‚ evolutionally‚ and genetically similar to humans; can they develop the same diseases we have today? Humans today

generation and the use of DNA information and analyses will contribute greatly to the field of criminal investigation and in effect‚ downgrade with expediency the crime rate in the country‚" Angara said. What are those for? DNA matching will become an ever more powerful weapon against crime. Law enforcement will increasingly be able to identify suspects from biological evidence at crime scenes‚ saving investigative time and protecting innocent people from suspicion. When DNA evidence is properly handled

Extraction and Analysis of Plasmid DNA from E. coli Cells Introduction A plasmid is an extra-chromosomal element‚ often a circular DNA. Since a plasmid is by definition an extra-chromosomal element‚ it cannot make use of any origin of DNA replication in a chromosome (BP site). Meaning that DNA synthesis within a plasmid depends on having an origin of DNA synthesis of its own. Plasmids are often found in bacterial cells‚ in which they are used as transfer agents for transmitting various antibiotic
