The enzyme RNA polymerase (RNAP) carries out transcription, copying DNA into RNA. It's the first step in gene expression, and a process fundamental to all life. But the inner workings of this ...

This image illustrates the process of gene transcription within a cell. The DNA double helix unwinds to expose a specific sequence, allowing RNA polymerase to synthesize a complementary pre-mRNA ...

Water molecules play an active, essential role in gene transcription, helping RNA polymerase II carry out the chemical steps ...

The fruit fly lacks the tRNA nuclear export receptor Exportin-t, which only exports end-processed tRNAs to the cytoplasm to ensure the completion of the processing steps in the nucleus. The related ...

Scientists have uncovered an unexpected way cells can generate cancer-driving proteins—by cutting RNA into shorter, ...
