This protein is capable of fluorescing green when exposed to ultraviolet or blue light. GFP is widely used as a <strong>reporter gene<\/strong> in molecular biology because it provides a visible marker of gene expression or protein localization. In experiments, GFP can be fused to other proteins, and its fluorescence can be used to track the expression and localization of the protein of interest within cells.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Molecular Type<\/strong>:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>pGLO<\/strong> is a <strong>plasmid<\/strong> (a DNA molecule).<\/li>\n\n\n\n<li><strong>GFP<\/strong> is a <strong>protein<\/strong> (a molecule made up of amino acids).<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Conclusion:<\/h3>\n\n\n\n<p>The main difference is that <strong>pGLO<\/strong> is a <strong>DNA plasmid<\/strong> containing the <strong>GFP gene<\/strong>, while <strong>GFP<\/strong> is a <strong>protein<\/strong> that the gene encodes.
