The [http://en.wikipedia.org/wiki/ribosome ribosome] is a complex composed of RNA and protein that adds up to several million daltons in size and plays a critical role in the process of decoding the genetic information stored in the genome into protein as outlined in what is now known as [http://sandwalk.blogspot.com/2009/10/ribosome-and-central-dogma-of-molecular.html the Central Dogma of Molecular Biology]. Specifically, the ribosome carries out the process of translation, decoding the genetic information encoded in messenger RNA, one amino acid at a time, into newly synthesized polypeptide chains. | The [http://en.wikipedia.org/wiki/ribosome ribosome] is a complex composed of RNA and protein that adds up to several million daltons in size and plays a critical role in the process of decoding the genetic information stored in the genome into protein as outlined in what is now known as [http://sandwalk.blogspot.com/2009/10/ribosome-and-central-dogma-of-molecular.html the Central Dogma of Molecular Biology].

The small subunit of the prokaryotic ribosome sediments at 30S<ref>[http://en.wikipedia.org/wiki/Svedberg Svedberg unit] in Wikipedia</ref>. It is composed of a 16S chain of RNA about 1,500 bases long (~500 kDa), plus about 20 protein chains. The proteins in the first small subunit determined range from about 3 kDa to 29 kDa. | The small subunit of the prokaryotic ribosome sediments at 30S<ref>[http://en.wikipedia.org/wiki/Svedberg Svedberg unit] in Wikipedia</ref>.
