Pour the mix into the filter and let it sit until all of the liquid drips down into the cup. Then the bananas were mushed more. But with bananas, we share about 50 percent of our genes, which turns out to be only about 1 percent of our DNA, emails Mike Francis, a Ph. DNA is organized into genes and stores genetic information. Do "ot $et the 0$ter touch the bottom, m#xture so that there are two $ayers o! 7 0 obj banana dna extraction lab report conclusion - chrissihart.com Studying DNA is one way scientists learn about what is necessary for life. Three examples of why scientists might need to indentify DNA are for genetic testing, body identification, and analysis of forensic evidence. Descr#be the appeara"ce o! Lastly, when good results were obtained, there was enough DNA to spool onto a rod or a plastic loop. The process of transferring information from DNA to RNA is called transcription. Water is a molecule of two hydrogen atoms and one oxygen atom (H2O)more. the so$ut#o" whe" the a$coho$, #s a%%e%. 0000004908 00000 n These comprise the genetic alphabet which in various combinations, will specify the components of proteins. In eukaryotic organisms, RNA most ofther carries the genetic information out of the nucleus, where chromosomes reside into the cytoplasm of the cell. Motivation: Recent technological promotions in the field of genomics have resulted in Following Generation DNA Sequencing Technologies. D. student in bioinformatics at the University of Georgia. . The banana DNA was circular and was very separated into many smaller pieces. A water bath was prepared. 0000008293 00000 n Some additional protocols for DNA extractions: Sex Influenced Female Dominant Inheritance, beakers 100ml and 2x250ml (or jars that same size), liquid dishwashing detergent (clear solution works better than cloudy), Make a 10% solution of dishwashing detergent in one of your 250ml beakers (make enough to fill the mortar half way), Add the 10% detergent solution to cover the fruit, Grind the banana in the soap solution until there are no lumps (this is the hardest part, have the students take turns), Fasten a coffee filter to the 250 ml beaker with a rubber band so there is room for the fruit to be poured into the filter, Pour the fruit and soap mixture into the filter and place in a cold place to filter, Clean up your lab area while you are waiting for the filtering to complete, Remove the filter and throw away the contents, Pour enough of the liquid into a test tube to fill it 2 cm high, Add twice the volume of 95% ethanol (try to layer the alcohol on top by gently pouring it down the side of the test tube), The DNA will precipitate in the boundary between the alcohol and the banana mixture as a cloudy mass. Lab Report on DNA Extraction from Kiwi and Strawberry fruits Using The subsequent conversion of the genetic information contained in RNA into a protein is called translation.
