How does the cell convert DNA into working proteins? The process of translation can be seen as the decoding of instructions for making proteins, involving mRNA in transcription as well as tRNA. But ...

The diagram illustrates the key stages of protein synthesis in a eukaryotic cell. It begins with transcription to produce pre-mRNA in the nucleus (1), followed by post-transcriptional modification (2) ...

The origin of the nucleus remains hotly debated among scientists, but new imaging and genomic data are shedding light on this billion-year-old mystery.

The eukaryotic spliceosome is a multi-megadalton ribonucleoprotein (RNP) complex found in eukaryotic nuclei that catalyzes the removal of introns (non-coding regions) from pre-mRNA and splices exons ...
