Study Notes
General Bio Lab Experiments
Microscopy Techniques
Microscopy techniques are essential tools for observing and analyzing small structures, such as cells, bacteria, and plant debris. Techniques include light microscopy, electron microscopy, and confocal microscopy, each with its unique advantages and applications.
Enzyme Activity Assays
Enzyme activity assays are used to measure the amount of enzyme in a sample and to determine the effectiveness of enzyme inhibitors or activators. Common assays include colorimetric, fluorometric, and luminescent methods, each detecting a specific enzyme reaction.
DNA Extraction Methods
DNA extraction methods are crucial for obtaining clean and concentrated DNA samples for further analysis. Common methods include phenol-chloroform extraction, salt precipitation, and enzymatic digestion, each with its advantages and limitations.
Gel Electrophoresis Procedures
Gel electrophoresis is a technique used to separate and visualize DNA or RNA molecules based on their size and charge. It involves the use of an electric field to move the molecules through a gel matrix, such as agarose or polyacrylamide. Techniques include horizontal and vertical gel electrophoresis, as well as denaturing polyacrylamide gel electrophoresis.
Plant Growth Experiments
Plant growth experiments are conducted to study the growth and development of plants under various conditions, such as different temperatures, light intensities, and nutrient levels. These experiments can help researchers understand the factors that influence plant growth and develop strategies to improve crop yield and quality.
