extraction, the soap pulls apart the fats (lipids) and proteins that make up the membranes surrounding the cell and nucleus Once these membranes are broken apart, the DNA is released from the cell The salt enables the DNA strands to come together, or aggregate The DNA precipitates out of the solution when the alcohol is added

Banana DNA Extraction

Banana DNA Extraction S0416 Objectives/Goals The objective is to determine if the banana#s DNA denatures overtime In this experiment, the bananas are categorized into three different ripening stages: the under-ripe, ripe, and over-ripe If the banana is in the under-ripe ripe stage, then it is expected to have the most amount of DNA Methods

Sonication for enzyme extraction has been proposed in this work As an example, Becerra et al [25] have used this procedure to extract intracellular yeast proteins, and found that sonication promoted a 50 times increase in protein extraction, when compared with other mechanical extraction procedures such as shaking by vortex or using glass beads
