How to get DNA from Banana Extraction
I. Introduction
DNA is found in all living cells. A polymer looks like a ladder that has been twisted in a helical form. . The sides of the ladder are acknowledged as the backbone of the DNA helix, and are involve of replicating sugar and phosphate units. DNA has a very important responsibility in the cell, as it encodes for all cellular proteins. s. The proteins expressed in a cell classify the distinctiveness of the cell, and organisms are compilation of several cells. Many of our physical characteristics are ascertained by the progression of our DNA.

Banana is the general name for herbaceous vegetation of the genus Musa and for the fruit they produce. It is one of the oldest farmed plants. They are inhabitant to tropical South and Southeast Asia. Banana is also used to depict Enset and Fe'i bananas, neither of which fit in to the abovementioned class. Enset bananas belong to the genus Ensete while the nomenclature of Fe'i-type cultivars is vague.

Removing DNA from a banana may sound like a complicated task, but it is not very difficult at all. The procedure involves a few common steps which include mashing, filtration, precipitation, and extraction. Squashing exposes a better surface area from which to extract the DNA. Substances are also added that will facilitate break-down cell membranes to discharge the DNA. The filtration step allows for the compilation of the DNA and other cellular substances. The precipitation step allows the DNA to break up from other cellular substances. At last, the DNA is detached from the solution. The DNA will be able to be seen at this stage because huge aggregates will have formed. 

The lengthy, fat fibers of DNA store up the information for the working of the chemistry of life. DNA is present in every cell of plants and animals. The DNA establish in banana cells can be extracted using ordinary, daily materials. We will use an extraction buffer including salt, to split up protein chains that attach around the nucleic acids and detergent to liquefy the lipid (fat) fraction of the banana cell wall and nuclear membrane. This extraction buffer will facilitate and provide us entrance to the DNA within the cells. Rationale:

Students will monitor first hand that DNA is in the food they consume. Students will study the simple technique of extracting DNA and each step is essential. To learn how chemical substances can split up the cell structures adjacent to DNA. To see how DNA looks like in food. To learn and see the physical structure of DNA through the naked eye. Statement of the Problem:

Is the process of human DNA extractions similar from the banana DNA extractions?

If the process of extracting the DNA of human will be similar to extracting the DNA of banana then both of the proteins will isolate because in extracting DNAs of different kinds of cells (plants or animals), purification is the first step in the study and handling of DNA that allow scientists to see the genetic syndrome or pattern of chain ladders in each kind of cells. Although, plants and animals have different structure of cells but both create DNA in nucleus. Scope and Limitations:

The scope for this lab is that DNA has critical part of each living thing, giving every cell its individual uniqueness, yet it is simply extracting from a cell. It would be appealing to watch this experiment open out in a laboratory with tools strong enough to observe this procedure and to see the individual strands of DNA. In addition, DNA might have been hard to understand but it’s amazing how this lab can see a lengthy DNA strands coiled. Lastly, it covers the aspect of the cells in nucleus and how the information of the DNA is kept deeper in human’s body, animal’s body, plants even in long or short period of time. DNA is a real secret hiding from every tiny cell in our body and surroundings. Lastly, we used the fruits to extraction because it’s a...
