DNA contains the instructions required to build each living thing. database? For example, scientists can identity genetic cell membranes if the cell wall guards the cell, DNA extraction, a detergent will cause the cell to pop open, or lyse, so that the DNA is released into solution. In this activity each material plays a specific role in helping to extract the DNA from the cells. Close the bag and very gently squeeze and move the saltwater and banana mush together. Approximately 3ml of banana solution were dispenced into each test tube. 1 ) Peel a banana and take about of it 2 ) In a ziplock bag , mash the banana until it is a liquid 3 ) Mix 20 m L of the extraction buffer with the banana liquid The goal of this lab is to extract the genetic material from an organism so that it can be seen with the naked eye . The remaining two bases, cytosine and thymine, are known as pyrimidines. DNA can be extracted and observed.

Banana DNA Extraction Lab Name: _____ Objectives: Describe where DNA is located in a plant cell. 1 1 . When subjected to certain conditions, it is possible to collect large amounts of DNA to make it visible. The salt will help the DNA stick together once it is out of the cells. This complementarity between adenine and cytosine nitrogenuos base pairs and between guanine and cytosine nitrogenuos base pase pairs, attracted to one another by hydrogen bonds, is critical to genetic function. every $#v#"g orga"#sm.
