Ribosomes

Ribosome’s Ribosomes are different in many sizes; usually they are made of three or four [|ribosomal RNA] molecules and more than 50 [|protein] molecules. There are two places that ribosome’s usually exist in the cell: suspended in the cytosol and bound to the [|endoplasmic reticulum]. These ribosome’s are called free ribosome’s and bound ribosome’s respectively. In both cases, the ribosome’s usually form aggregates some of the functions of Ribosome’s are the workhorses of [|protein biosynthesis], the process of translating mRNA into [|protein]. Proteins that are formed from free Ribosome’s are released into the cytosol and used within the cell. Also Ribosome’s read the sequence of [|messenger RNAs] and assembles [|proteins] out of [|amino acids] bound to [|transfer RNAs]. The mRNA comprises a series of [|codons] that dictate to the ribosome the sequence of the [|amino acids] needed to make the protein. The Ribosome’s were discovered by cell biologist from Rome George Palade in the mid-1950s with the use of a high-powered electron microscope. But the name was given to the Ribosome’s in 1958 by scientist Richard B. Roberts. [] [] [] Neo and David
