The discovery of ribosomes dates back to the 1950s, when George Palade first observed dense particles in the cytoplasm of cells using electron microscopy. These particles were later named "ribosomes" ...

This image highlights two alternatives for the ribosome to be recruited to an mRNA that is still being synthesized by RNA polymerase (RNAP). RNAP (left, red) can directly deliver the mRNA to the entry ...

Scientists at the University of California, Santa Cruz, have trapped the ribosome, a protein-building molecular machine essential to all life, in a key transitional state that has long eluded ...

Angiogenin is a well-characterized enzyme that has a variety of important roles; it can trigger the growth of new blood vessels, is involved in cell survival, migration, and proliferation, and has ...

Transcription and translation are processes a cell uses to make all proteins the body needs to function from information stored in the sequence of bases in DNA. The four bases (C, A, T/U, and G in the ...

Ribosomes, the cell's protein-making factories, consume large amounts of energy as they build the proteins that keep cells alive and functioning. When cells experience stress—such as lack of nutrients ...

Neurons have a "hibernation mode." Scientists discover how brain cells use RNA tentacles to lock their protein factories together to survive when energy is low.

Ribosomes are molecular machines that translate messenger RNA (mRNA), which is transcribed from DNA, into proteins. Scientists have now learned more about ribosomes in nature, and their function. This ...

Under stress, animal cells pair inactive ribosomes into RNA-linked disomes. A ribosomal RNA “kissing loop” joins them, protecting ribosomes and reducing protein synthesis to conserve energy.<br /> ...

Ribosomes are large molecular machines made of protein and RNA that build all proteins in the cell. Because protein production is extremely energy-intensive, cells rapidly reduce protein synthesis ...
