Proteins are the infinitely varied chemicals that make cells work, and science has a pretty good idea how they are made. But ...

By tethering RNA polymerase with the coupling transcription factor NusG or its paralog or version, RfaH, which threads the ...

The protein factories of our cells are much more diverse than we thought they were. Scientists from the Netherlands Cancer ...

The r-proteins needed for their formation must travel from the cell plasma to the site in the nucleus where the ribosomes are manufactured, called the nucleolus.

In eukaryotes, new ribosomes are formed predominantly in the cell nucleus. Therefore, the r-proteins needed for ribosome formation must travel from the cytoplasm of the cell to a site in the ...

Once the ribosome is made it passes from the nucleus into the rest of the cell. There, it will carry out its function and translate proteins for use within the cell. Free and membrane-bound ribosomes ...

A ribosome is composed of two subunits: large and small. During translation, ribosomal subunits assemble together like a sandwich on the strand of mRNA, where they proceed to attract tRNA ...

The evolution of the ribosome, a large molecular structure found in the cells of all species, has been revealed in unprecedented detail in a new study.

This mRNA carries the code for Thrombin out of the nucleus and onto the cellular factory floor. Our mRNA drifts until it runs into a ribosome, a protein-making machine.

Ribosomes are formed in an area of the nucleus called the nucleolus, before being exported to the cytoplasm, where some ribosomes float freely. Other cytoplasmic ribosomes are bound to the endoplasmic ...
