The ribosome serves as the essential molecular machine that translates genetic information carried by messenger RNA (mRNA) into functional proteins. Comprised of two distinct subunits, the ribosome ...

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 ...

Christine Dunham is a leading expert on the ribosome—an elaborate macro-molecular machine that operates like a factory within ...

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 ...

Within a cell, DNA carries the genetic code for building proteins. To build proteins, the cell makes a copy of DNA, called mRNA. Then, another molecule called a ribosome reads the mRNA, translating it ...

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 ...

The process of translation by ribosomes, which functions as a factory of protein synthesis, may be impeded by ‘ribosome arrest peptides’ (RAPs). However, underlying mechanisms remain elusive.
