Understanding Gene Expression and Traits

The video explains how genes in organisms express traits through proteins. It begins with an introduction to traits, using examples from the animal kingdom. The video then delves into the structure of genes and chromosomes, explaining how DNA is organized. It highlights the role of proteins, particularly the green fluorescent protein (GFP), in expressing traits like bioluminescence in jellyfish. The video also discusses the diverse functions of proteins in cells and the importance of their structure. Finally, it explores the scientific applications of GFP in research, such as tracking proteins and studying diseases.
