EXPORT MECHANISM: The tRNA must mature inside the nucleus before export. tRNAs are aminoacylated, and only tRNAs charged with an amino acid are exported efficiently. Export occurs when the tRNA is ...

Scientists have uncovered key new information towards understanding the crucial first step in protein synthesis, the process by which the genetic code, harbored within DNA and copied into RNA, is ...

Rush hour never ceases at the nucleus’ border. Gene products begin their lives in the nucleus as strands of mRNA that ship out into the cytoplasm, where they serve as templates for protein synthesis.

This narrated animation illustrates the process of protein synthesis, starting with chromosomal DNA inside the cell's nucleus. A gene is transcribed into messenger RNA, which leaves the nucleus and ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 84, No. 8 (Apr. 15, 1987), pp. 2317-2321 (5 pages) The subcellular distribution of v-sis-related protein(s) was ...

To better understand how RNA in bacteria gives rise to protein -- and potentially target these processes in the design of new antibiotics -- researchers are turning their attention to the unique way ...

Factor-pooling by ribosomes caught on video using state-of-art high-speed atomic force microscopy technology. Ribosomes are the complexes of ribonucleoproteins at the heart of protein synthesis in ...

Disease-causing huntingtin, shown in red, interacts with ribosomes, shown in green, in a striatal neuron. The nucleus is blue. [Nicolai Urban of Max Planck Institute for Neuroscience in Jupiter, ...
