In summary, molecular biology photometry is a technique that uses a spectrophotometer to measure the absorbance of light by molecules in a sample. This allows for the quantification of DNA, RNA, and proteins in molecular biology experiments. It is a fast, accurate, and non-destructive method with relatively low cost. However, it requires a pure sample and cannot detect molecules with low absorbance or distinguish between different types of molecules. It is also limited to measuring molecules with aromatic rings, such as DNA, RNA, and proteins.
