No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Scientists have long tried to figure out the precursors to both RNA (ribonucleic acid) and DNA (deoxyribonucleic acid), as well as how the two emerged.
