Extracting DNA from a Banana and Other Fruits Introduction All living things, bananas and people included, pass on information from one generation to the next using the same basic material, DNA. You must cite our web site as your source. The banana DNA was easy to see as it was a light pink/clear and it was chunky and had thick pieces when picked up with the skewer but it appeared shredded in the liquid. About 60 percent of our genes have a recognizable counterpart in the banana genome! When subjected to certain conditions, it is possible to collect large amounts of DNA to make it visible. It does not store any personal data. The nanodrop system revealed that at an absorption of 260 wavelengths, the DNA measured 7.49 using a 374.66 ng/ul sample.

Cells reproduce in part by passing deoxyribonucleic acid (DNA) from parent cells to offspring cells. DNA can be extracted and observed. We understood how a buffer solutions disrupts the plasma membrane and releasing cellular components into the solution. In the cytoplasm, the information in RNA is translated into proteins, which serve as the end products of most all genes. 0000002648 00000 n DNA is made up of a series of monomers called nucleotides. 0000002685 00000 n Then alcohol added to the solution causes the DNA to precipitate out. The salt enables the DNA strands to come together, or aggregate. During the procedure of the lab, a ratio of one banana per one cup (250 milliliters) of distilled water had to be mixed together in a blender. The positively charged sodium ions in the salt help protect the negatively charged phosphate groups that run along the backbone of the DNA. Complementarity serves as the basis for both the replication of DNA and for the transcription of DNA into RNA. My Thus, DNA is present in all living organisms.
