Modeling of DNA and protein organization levels with Cn3D software.
The molecular structure of living organisms and the complex interactions amongst its components are the basis for the diversity observed at the macroscopic level. Proteins and nucleic acids are some of the major molecular components, and play a key role in several biological functions, such as those of development and evolution. This article presents an educational, bioinformatics-based process, designed to enhance a better understanding of the structure of the above molecules. In addition, by using selected protein molecules, it attempts to clarify protein organization levels and how these are related with the structural and functional diversity, which define the biodiversity of living organisms at the macroscopic level. In the framework of this project, molecular modeling has been performed using the Cn3D software, created by the US National Center for Biotechnology Information (NCBI). Cn3D is a user friendly application, which is easy for students to get familiar with quickly. Our suggested process may be easily enriched by a multitude of protein, nucleic acid, or other molecule structures, which are freely accessible at NCBI website. The described process has been implemented by students (n = 225) of the 5th high school grade, in two high schools in Greece. © 2016 by The International Union of Biochemistry and Molecular Biology, 45(2):126-129, 2017.
