Experiment I: For each of the following, please choose the appropriate function of the substance. Liquid Detergent in the Extraction Buffer [Choose] [ Choose ] Salt in the Extraction Buffer Alcohol in the Extraction Buffer \( \begin{array}{l}\text { [ Choose ] } \\ \text { Negates the negative charges in the DNA } \\ \text { Enzymes that cut DNA } \\ \text { Source of DNA } \\ \text { Precipitates the DNA } \\ \text { Dissolves the plasma membrane and binds proteins and carbs }\end{array} \) [ Choose ] DNases

To determine the appropriate function of each substance in the extraction buffer, let's analyze each component: 1. **Liquid Detergent in the Extraction Buffer**: - The function of liquid detergent is to **dissolve the plasma membrane and bind proteins and carbohydrates**. Detergents disrupt lipid bilayers, allowing the extraction of cellular components. 2. **Salt in the Extraction Buffer**: - The function of salt is to **negate the negative charges in the DNA**. Salt helps to stabilize the DNA by neutralizing the charges on the phosphate backbone, which facilitates the precipitation of DNA. 3. **Alcohol in the Extraction Buffer**: - The function of alcohol is to **precipitate the DNA**. Alcohol (usually ethanol or isopropanol) is used to precipitate DNA from the solution, allowing it to be collected. 4. **DNases**: - The function of DNases is to **enzymes that cut DNA**. DNases are enzymes that degrade DNA, which is important to prevent contamination during the extraction process. Now, let's summarize the choices: - **Liquid Detergent**: Dissolves the plasma membrane and binds proteins and carbohydrates. - **Salt**: Negates the negative charges in the DNA. - **Alcohol**: Precipitates the DNA. - **DNases**: Enzymes that cut DNA.
