Structure of the RNA square.

An advanced study by the scientists and biochemists at University of California has recently contributed to our understanding of the structure of RNA solved at resolution 2.2 angstrom. As per the study published by a journal published under the Proceedings of the National Academy of Sciences of United States of America, this is the smallest and the finest structure ever detailed and is the farthest that mankind has reached in this field.

The team of scientists headed by Thomas Hermann explained that since the Ribonucleic acid has a unique role of carrying information from the DNA to the proteins, this nano square could possibly be exploited in making self-assembling nano materials for programmable molecular entities.

Secondary structure of the RNA square.

This study on the structure of RNA has shown that the nano square contains four different corners each having a different set of arrangement of nucleotides. An L shaped object or a nano corner is the minutest structure that can be built from a double stranded RNA. When four such nano corners assemble themselves, what we get is known as the nano square; the tiniest square that has ever been made from the combination of two different nucleotides following a complex mechanism.

According to the team of scientists who made this discovery, this study could prove to be a step forward in the field of nanotechnology and modifications of this nano square may provide details about the distinct architecture of RNA, that may possibly be used to design nano materials.
