TITLE: EXTRACTION OF DNA

OBJECTIVE:
Extract DNA from yeast, onion and apple.

INTRODUCTION:
Every cells of living organism contains genetic materials known as deoxyribonucleic acid, DNA. It can be isolated from tissue sample of living things by separating it from other cellular component in a manner that still preserves its structures. The structure of DNA is double-stranded helices that made up from the monomer of nucleotides. Each of the nucleotides composed of three parts that are the phosphate group, deoxyribose sugar backbone and also nitrogenous bases (Adenine, Guanine, Thymine and Cytosine). This nitrogenous base are arranged in sequence and holds the information and coding for controlling the physical trait that we all have as well as the regulation of our body.
DNA extraction is simply a process that results in separation of DNA from the cells or viruses that are hosting it. Through the meaning is simple but the process is not. When we go into the peculiar details of DNA extraction, we realize that it’s more of an initial stage in other intensive DNA testing processes. DNA test could be performed for any reason; however for any DNA testing to happen the first stage normally is the isolation and extraction of DNA molecules from the cells that they reside in.
DNA extraction follows a series of step, stripping all proteins from the DNA and the extraction protocols have to make sure that the

    Deoxyribose Nucleic Acid (DNA) is a polynucleotide molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses. Most DNA molecules are double stranded helices, consisting of two polynucleotide strands made up of simpler molecules known as nucleotides. A nucleotide is made up of an organic nitrogenous base, a deoxyribose sugar and phosphate groups. It is order of these bases which make up the genetic code; a set of rules, by which information is encoded within genetic material.…

    Background information: The long thick fibers of DNA store the information for the function of the chemistry of life. DNA is present in every cell of plants and animals. The DNA found can be extracted using common, everyday material. We will use an extraction buffer containing salt, to break up protein chains that bind around the nucleic acids, and dish soap to dissolve the lipid (fat) part of the strawberry cell wall and nuclear membrane. This extraction buffer will help provide us access to the DNA inside the cells.…

    1. Why Do Cheek Cells Make A Convenient Source For Obtaining DNA Samples?

    In this laboratory, two experiments were performed; the first one was performed to determine whose fingerprint was found at a crime scene. For this experiment, four-10 mL DNA samples were placed in a well of agarose gel, using a micropipette; the sample was also covered in a TBE buffer solution. The four samples were then put in the electrophoresis apparatus to be run through electrophoresis. After 20 minutes, the samples were ready and the results were documented; it was found that suspect “B” was the culprit. The second experiment was performed to isolate and extract DNA from epithelial cells.…

    Gel Electrophoresis Research Paper

    Restriction enzymes are tools in DNA research that can cut DNA into exactly needed pieces. Certain cuts can be rough, while others can be clean. Certain cuts can have an organized pattern to have a staggered cut. Other cuts will leave complementary bases with them. Electrophoresis allows the manipulation of DNA to separate and organize those parts. Electrophoresis is the substrate electric movement of the separation of DNA. Gel Electrophoresis can separate both DNA and RNA. This can also allow the knowledge of the unknown bases of a strand of DNA. This can allow the knowledge of familiar patterns that can create a unique signature. Separation of these molecules…

    Lab Report

    Lichens are a sybiotic association of fungus (mycobiont) and algae (Pediastrum boryanum . The fungus engulfs the algae, then supplies carbs, nitrogen, and vitamins while the algae photosynthesizes. This unusual relationship enables the lichen to grow in environments where neither fungus nor algae would normally be able to solely survive. They are found on every continent, ranging all the way from the freezing Arctic to the sweltering grasslands of Africa. Even though they can live in such extreme conditions, they do require clean air. This is why they are excellent environmental indicator. An indicator species is an organism whose presence or absence reflects the overall health of an environment. Lichens flourish where there is good air quality; however, they cannot survive where the air is polluted and toxins loom. This is because they have no stomata, or pores, to shut to keep the toxins out; therefore, absorbing all of the pollutants in the air. Because they are such unique organisms, they accumulate different metal anions in the air than other organisms, like plants do, for example. Lichens attract toxic metal ions. An ion is a charged atom. If the ion has a positive charge, it is a cation. An ion with a negative charge is an anion. During the ion exchange process, Hydrogen, an anion, is released and metal cations move in. This process occurs when lichens are exposed to polluted air. When the lichens are dropped into any of the metal solutions, their cell wall releases the methylene blue ions, which are replaced by metal cations. Upon their detachment, the ions integrate into the solution, which in turn, colors it blue. The darker the solution, the more metal cations taken in by the lichen. Valence is a measure of how much an atom wants to combine with something else. If the valence of a metal ion affects lichen uptake, then the higher the cation, the…

    DNA is one of the nucleic acids information-containing molecules in the cell (ribonucleic acid, or RNA, is the other nuclei c acid). DNA if found in the nucleus of every human cell. The information is DNA: guides the cells (along with RNA) in making new proteins that determine all of our biological traits. DNA gets passed (copies) from one generation to the next. DNA in a cell is really just a pattern made up of four different parts called nucleotides. Image a set of blocks that has only four shapes, or an alphabet that has only four letters. DNA is a long string of these blocks or letters.…

    In the article “How Boys Become Men”, written by John Katz, he analyzes situations he experienced while growing up. Katz believes that boys become men by not showing fear or feelings and not ratting on others. As in the novel, The Other Wes Moore, both Weses are forced to become men at an early age. They experience events that push them to make decisions that make them grow and think like men do. Katz details the maturation process for boys, as the book, The Other Wes Moore, does with both Weses. They make decisions and take actions to mature and become a men.…

    DNA extraction lab

    There are three specific steps required to isolate DNA from its cellular contents. The steps used to remove and expose DNA from its cell are: breaking down the food type you are using by crushing it, for example a banana or strawberries, exposing the substance to a sodium chloride (NaCl) solution, subjecting the product to detergent solution (dH2O), filtering the solution and lastly, the addition of ethanol. When beginning with a solid substance, such as a banana, crushing the substance allows for breaking down the cell membrane and cell wall, if using a plant cell. This ultimately, removes the contents of the cell from the deoxyribonucleic acid (DNA) and further exposes it for the detergent solution. After this step, one would use NaCl solution to stabilize the DNA, since we know that it is negatively charged, due to the phosphate functional group. The way this occurs is when NaCl is added to the solution the molecule dissolves and forms ions. As a result, the positively charged ions neutralize the negative charge on the DNA molecule ("Discovering DNA" 20 Feb. 2014). The technique used to separate the DNA is by adding a detergent liquid to the solution, which allows for the cell membrane to break down. This step specifically emulsifies the phospholipids and proteins that make up the cell membrane ("Discovering DNA" 20 Feb. 2014), in order to further expose the DNA. Then in order to separate the DNA from the proteins and lipids one must use a filter paper with an appropriate pore size so that the flow rate of the solution is effective. Once the flow rate is minimal, the excess in the filter, consisting of cell debris and banana residue, can be disposed and then the filtrate is focused upon. With the specific amount of…

    DNA STRAWBERRY CONCLUSION

    The hypothesis for this lab is if strawberry DNA is separated from other components, then when it is placed in a insoluble solution the DNA can eventually be isolated. DNA is deoxyribonucleic acid. Its a self replacing material present in all living organisms as the main constituent of chromosomes. It is the fundamental and distinctive characteristics of someone or something, especially when regarded as unchangeable. DNA extraction is the removal of deoxyribonucleic acid from the cells or viruses in which it normally resides, it is useful to biologists. One technique for extracting DNA is by precipitating it with alcohol. Another technique is Hirt DNA extraction, which is an isolation of all extrachromosomal DNA in a mammalian cell. Extracting DNA is useful for biologists because it can be used for the experimental idea for patients who require a organ donation. DNA isolation is a routine procedure to collect DNA for subsequently molecular or forensic analysis.
