Q & A

What is a wet lab, and what kind of work is done there?

A wet lab is a laboratory where experiments involving DNA, RNA, and protein work are conducted. It is also where chemical reactions are performed, using various equipment to mix chemicals and measure small amounts of fluids for experiments.

What is the purpose of pipettes in a molecular biology lab?

Pipettes are used to measure and transfer small amounts of fluids with precision. These measurements are essential for conducting reactions or experiments, as they allow scientists to work with very small quantities of chemicals and biological materials.

Why do different chemicals need to be stored at different temperatures in the lab?

Different chemicals require specific temperature conditions to prevent degradation and maintain their effectiveness. By storing them at the proper temperature, scientists ensure that the chemicals remain fresh and stable for use in experiments.

What is the purpose of a gel imaging room in a molecular biology lab?

The gel imaging room is used to visualize DNA, RNA, or protein samples. Scientists use gels, stains, and specialized equipment like PCR machines to separate and visualize molecules to analyze their properties or results from experiments.

What role does a PCR machine play in molecular biology?

A PCR (Polymerase Chain Reaction) machine is used to amplify small amounts of DNA, making it easier for scientists to analyze and study specific DNA sequences. It works similarly to a photocopy machine for DNA, replicating it many times over.

What is a negative eighty-degree Celsius freezer used for in the lab?

The negative eighty-degree Celsius freezers are used for long-term storage of biological samples, such as DNA, tissues, or other sensitive materials. These extremely cold temperatures prevent degradation and preserve the integrity of the samples.

How does tissue culture work in plant regeneration?

Tissue culture involves growing plants in a sterile environment to avoid contamination. Small pieces of plant tissue are cultured in a medium that mimics developmental stages, allowing for the creation of clones or regenerated plants from a single sample.

What are GCMs and why are they important in the lab?

GCMs (Gas Chromatographs and Mass Spectrometers) are used to analyze the chemical composition of substances, such as the flavor and aroma compounds in plants. The GCM separates compounds in a sample, and the mass spectrometer identifies them based on their unique molecular fingerprints.

What is the significance of spectral science rooms in plant research?

Spectral science rooms are used to experiment with different light wavelengths to observe how plants grow and react to specific light treatments. The different light conditions allow scientists to study how plants' growth patterns are influenced by various light environments.

How does the greenhouse contribute to the lab's plant research?

The greenhouse provides a controlled environment for growing plants, including flowers like petunias. The lab uses the greenhouse to study plant growth under specific conditions and observe how different treatments, such as light exposure or temperature, affect plant development.
