38 strawberry dna extraction lab answers

DNA is extracted by a four step process: the strawberries are first crushed, which mechanically breaks cell walls, and facilitates degradation by pectinase and cellulase. A detergent solution is then used to dissolve the cell membrane and nuclear membrane, which are composed of a phospholipid bilayer. I quickly review the modifications we have made to the lab instructions, and I remind the students to complete the Strawberry DNA Extraction Questions once they have finished with the lab. These videos represent the students' favorite part of the lab and are two steps that I generally warn them about.
