10 Facts about Ribosomes

Post On: May 7, 2017

You will get important information about a complex molecular machine, which can be found in all living cells of human being on Facts about Ribosomes. The amino acids will be connected each other through Ribosomes. There are two main elements of Ribosomes. They are the large subunit and small subunit. The former one has something to do with the formation of polypeptide chain. It joins the amino acids. The latter one has the ability to reads RNA. Check other facts about ribosomes below:

Facts about Ribosomes 1: rRNA

rRNA or ribosomal RNA is found in each subunit of ribosome along with ribosomal proteins.

Facts about Ribosomes 2: the translational apparatus

The term the translational apparatus is used to call the Ribosomes and their connected molecules.

George Emil Palade was the Romanian cell biologist who first observed Ribosomes in 1950s. He spotted dense granules or particles using his electron microscope.

Facts about Ribosomes 4: the term Ribosomes

In 1958, Richard B. Roberts coined the term ribosome to call the dense granules. The term was well received by other scientists.
