Buffer

The cell is made up of the cell wall, fatty cell membrane and contain a nucleus with the DNA inside and lots of proteins.

The cell wall breaks after the it is exposed to extreme temperatures such as being frozen.

The dishwashing liquid causes the cell membrane to be dissolved.

As the strawberry contains an enzyme called DNase, it can break up the proteins If the fruit does not have DNase, then meat tenderizer works also to break up the protein.

The salt causes the DNA stick together. As DNA does not dissolve in alcohol so it coagulates to form a jelly like substance.
