/SM 0.02 Avery and the other scientists discovered that DNA is the nucleic acid that stores and transmits the genetic information from one generation of an organism to the next. 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. Then the DNA can be precipitated out of the solution by adding alcohol. Once these membranes are broken apart, the DNA is released from the cell. Genetic testing can best be defined as a process in which an individuals DNA is isolated and tested for the presence of specific genes or defects that could indicate the future onset of some disease. <<37B5D6E5CA566B46AF6D8E49138E4E7A>]>> 1 0 obj For more info, see, https://askabiologist.asu.edu/activities/banana-dna, Public Service and <> The process involves a few general steps, including mashing, filtration, precipitation, and extraction. 4. startxref stream the DN +co$or' texture', The soap so$ut#o" co"ta#"s so%#um $aure$ su$!ate' wh#ch, the soap pu$$s apart the !ats +$#p#%s a"% prote#"s that. 0000008815 00000 n /Filter /DCTDecode Analysis & Conclusion/Discussion - Jessica's RESEARCH PROJECT - Weebly Then the bananas were mushed more.
