(Image: adapted from National Human Genomw Research Institute) Ribosomes are composed of two main subunits: a small subunit and a large subunit. In eukaryotes, the small subunit is called the 40S ...

Ribosomes are composed of two subunits, the small and large subunits, each containing specific rRNA molecules. The main types of rRNA include: Small Subunit rRNA: In prokaryotes, the small subunit ...

Surprisingly, it does this in the absence of both messenger RNA and the ribosome’s small, message-reading subunit. The ribosome is a large molecular complex of RNA and protein. When eukaryotic ...

Researchers from Stanford University and LMU have uncovered how cells renew their endoplasmic reticulum’s protein factories.

First, three initiation factor proteins (known as IF1, IF2, and IF3) bind to the small subunit of the ribosome. This preinitiation complex and a methionine-carrying tRNA then bind to the mRNA ...
