Question

what are the component of ribosome ?

Answer 1

A ribosome is a component of cells that assembles the twenty specific amino acid molecules to form the particular protein molecule determined by the nucleotide sequence of an RNA molecule.

Answer 2

:-) the exact functions of the components of ribosomes have been fairly unclear for a long time, until there was an article in "science" about this exact manner TODAY: http://www.sciencemag.org/content/334/6058/941

but this is excessive information for you :-) the points you ought to know were found long ago and are the following:

- the ribosome is a macromolecular complex: it consists of amino acids (protein) AND ribonucelic acids (ribosomal RNA or rRNA)

- because of it's size (1 mol ribosomes would weigh 4.2 tons!), it is made out of several subunits which are synthesized apart from each other and assemble right on the RNA

- the rRNA actually makes up most of the ribosome. the size of the RNA parts is measured in Svedberg ( http://en.wikipedia.org/wiki/Svedberg).
