Electrophoresis of RNA
Liver RNA. Electrophoresis gel containing RNA (ribonucleic acid) isolated from liver tissue. The RNA molecules (white bands) are being observed under ultraviolet light, which causes a chemical present in the gel to fluoresce. Electrophoresis separates molecules according to their size, by applying an electrical current to samples loaded onto the gel. The bands present in each sample represent different types of RNA. RNA is a nucleic acid that is involved in directing protein synthesis. Different RNA sequences are present in different tissues, representing differing patterns of gene expression

EDITORS COMMENTS
This print showcases the process of electrophoresis, a fundamental technique in molecular biology research. The gel contains RNA molecules isolated from liver tissue, and under the influence of ultraviolet light, these RNA molecules emit a mesmerizing glow. Electrophoresis allows scientists to separate these molecules based on their size by applying an electrical current to the gel-loaded samples. The distinct white bands visible in each sample represent different types of RNA present in the liver tissue. These variations in RNA sequences reflect diverse patterns of gene expression across different tissues. As a nucleic acid crucial for directing protein synthesis, RNA plays a vital role in genetic processes. The fluorescence caused by ultraviolet light is particularly fascinating as it highlights the presence and distribution of specific RNAs within the gel matrix. This visual representation aids researchers in analyzing and understanding gene expression patterns at a molecular level. This image not only captures the beauty of scientific exploration but also serves as a reminder that every living organism possesses unique genetic information encoded within its cells. Science Photo Library has once again provided us with an awe-inspiring glimpse into the intricate world of molecular biology research through this stunning photograph.
