For the genes DNA to subsequently influence an inherited trait, the stored genetic information in the DNA in most cases is first transferred to a closely related nuclei acid, RNA or ribonucleic acid. During the DNA extraction, the soap pulls apart the fats (lipids) and proteins that make up the membranes surrounding the cell and nucleus. The banana mixtures were cooled in the ice chest containing ice for 2 minutes.
