Developing B and T lymphocytes assemble new immunoglobulin and T-cell receptor genes from discrete arrays of variable (V), diversity (D) and joining (J) gene segments. This process, known as V(D)J ...

A bacterial protein helps to stop transcription—the process of making RNA copies of DNA to carry out the functions of the cell—by causing the cellular machinery that transcribes the DNA to pause at ...

The CRISPR-Cas gene-editing system has long been the focus of research as a promising tool in genome editing. However, the emphasis has been on its underlying mechanisms and nucleases. In contrast, ...

Scientists have found the first example of how micro-RNA regulates wood formation inside plant cells and mapped out key relationships that control the process. For more than a decade, scientists have ...
