Final Answer:
The meat tenderizer, containing enzymes like papain, functions in a DNA laboratory experiment by breaking down cell membranes and nuclei, facilitating the release of DNA during the extraction process.
Step-by-step explanation:
In the context of a DNA laboratory experiment, meat tenderizer, which contains enzymes like papain, is often used to aid in the extraction of DNA from cells. The cell membrane and nuclear envelope protect DNA within cells, and meat tenderizer helps break down these barriers. The enzymes in meat tenderizer break down proteins, including those found in cell membranes and nuclei, facilitating the release of DNA.
The main function of meat tenderizer is to digest proteins and disrupt cellular structures, allowing easier access to the DNA. This process, known as cell lysis, is a crucial step in DNA extraction. By breaking down cellular components, the DNA is liberated from the cell and other cellular debris. Subsequently, other steps in the DNA extraction process, such as precipitation and purification, can be carried out more efficiently, leading to a higher yield of intact and pure DNA for further analysis or experimentation.
