DNA Extraction and Quantification: Methods and Electrophoresis in Molecular Biology
DNA extraction and quantification is a fundamental procedure in molecular biology that allows the isolation of genetic material from cells and the measurement of its quantity and quality for downstream analysis. These techniques are essential to ensure that the extracted DNA is suitable for applications such as PCR amplification, enzymatic digestion, or fragment separation by […]
Electrophoresis
What is electrophoresis? Electrophoresis is a laboratory technique used to separate charged molecules, such as DNA, RNA, or proteins, based on their size and electrical charge, using an electric field and a porous medium (gel) that acts as a sieve. How does it work? This allows the separation and visualization of DNA, RNA, or protein […]
In chemistry, what is phenolphthalein and what is its function?
What Is Phenolphthalein? Phenolphthalein is an organic compound widely used in analytical chemistry, mainly as an acid-base indicator. Its most well-known characteristic is its ability to change color depending on the pH of the medium, which makes it a fundamental tool in the practice of titrations or chemical assessment processes. From a chemical point of […]
