New RNA Letter Regulates Gene Expression
Science Related News
A new study finds that RNA, considered the DNA template for protein translation, often appears with an extra letter -- and this letter is the regulatory key for control of gene expression. The discovery offers insight into different RNA functions in cellular processes and contributions to the development of disease.

Scientists take big step toward recreating primordial 'RNA world' of 4 billion years ago
Scientists have succeeded in creating a ribozyme that can basically serve both to amplify genetic information and generate functional molecules, a big step toward the laboratory re-creation of the 'RNA world' generally believed to have preceded modern life forms based on DNA and proteins.
