(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 ...

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 ...

These 70S ribosomes consist of two subunits: a 30S small subunit and a 50S large subunit. The 30S subunit contains a 16S ribosomal RNA (rRNA) molecule, while the 50S subunit harbors 23S and 5S ...
