Introduction. This lab will determine the presence or absence of amplified DNA in your samples by visualization on an agarose gel. Arthropod and Wolbachia DNA, if present, will be distinguishable based on the size, or base pair (bp) length, of the DNA molecule.
Objective: -Use chemical indicators to test for glucose and starch. -Demonstrate the permeability of an artificial cell for glucose, starch, and Starch Indicator Solution and explain their diffusion.

In this lab, students learn how to use gel electrophoresis as a conservation tool.
Because nucleic acids are negatively charged ions at neutral or alkaline pH in an aqueous environment, they can be moved by an electric field. Gel electrophoresis is a technique used to separate charged molecules on the basis of size and charge.
In general, gel electrophoresis is a process by which the macromolecules within a sample are separated from one another on the basis of size. The process can be applied to different types of macromolecules such as proteins and nucleic acid (DNA and RNA).
Gel electrophoresis. Hydrated gel networks have many desirable properties for electrophoresis. They allow a wide variety of mechanically stable experimental formats such as horizontal/vertical electrophoresis in slab gels or electrophoresis in tubes or capillaries.
