Lab Procedures in Illustration
The illustration depicts several laboratory procedures, each serving a specific purpose in scientific research. Three of the most accurate procedures depicted are:
Micropipetting
Micropipetting involves accurately measuring and transferring small volumes of liquid. The procedure involves using a micropipette, a specialized tool designed for precise liquid handling. The key steps include:
- Selecting the appropriate micropipette tip based on the volume of liquid to be measured.
- Calibrating the micropipette to ensure accuracy.
- Aspirating the liquid by slowly depressing the plunger.
- Dispensing the liquid by slowly releasing the plunger.
Micropipetting is crucial in various laboratory techniques, such as preparing solutions, performing assays, and analyzing samples.
Gel Electrophoresis, List 3 correct lab procedures depicted in the illustration
Gel electrophoresis is a technique used to separate and analyze DNA or RNA molecules based on their size and charge. The procedure involves:
- Preparing an agarose gel by mixing agarose powder with a buffer.
- Loading the DNA or RNA samples into the gel wells.
- Applying an electrical current to the gel, causing the molecules to migrate through the gel.
- Visualizing the separated molecules using a fluorescent dye or UV light.
Gel electrophoresis is widely used in molecular biology for applications such as DNA sequencing, genotyping, and gene expression analysis.
Spectrophotometry
Spectrophotometry is a technique used to measure the absorption or transmission of light by a sample. The procedure involves:
- Preparing a sample solution and placing it in a cuvette.
- Using a spectrophotometer to pass light through the sample.
- Measuring the amount of light absorbed or transmitted by the sample.
- Interpreting the results to determine the concentration or properties of the sample.
Spectrophotometry is commonly used in various fields, including biochemistry, environmental science, and pharmaceutical analysis.
