Ribosomes.
Proteins are assembled in the cytoplasm (outside the nucleus where DNA is stored in most Eukaryotes) in a molecular machine called the Ribosome. The ribosome is itself partly built up of proteins, and partly (the biggest part) of rRNA. Ribosomes assemble proteins according to instructions coded into the nucleotide sequence of mRNAs (messenger RNAs).The sequence of nucleotides in mRNA determines the sequence of amino acids in the protein (proteins are folded chains of amino acids). Each three nucleotides in the mRNA chain determines which amino acid to place in one specific position in the amino acid chain that builds up the protein.The message for proteins synthesis comes from nucleus. mRNA, ribosome, tRNA and enzymes together synthesize proteins. They are further modified by post translational modifications such as glycosylation, acylation and folding process in ER and Golgi.

Breakdown of proteins produce aminoacids.

In all cells, the ribosome produces proteins from amino acids and all three forms of RNA (mRNA, rRNA, and tRNA) in a process called translation. All RNA comes from transcription that occurs in a eukaryotic cell's nucleus or in a prokaroyte's cytoplasm. Therefore, a eukaroyte's ribosomes often cover the rough endoplasmic reticulum (ER) that often surrounds the nucleus, so it's convenient for those ribosomes to translate the RNA into proteins soon after the RNA leaves the nucleus from transcription.

DNA contains the code for synthesizing proteins. DNA transcribes itself into MRNA (memory RNA), which then leaves the nucleus and translates into TRNA (Transfer RNA) which goes around the cell to retrive the amino acids that were coded into the DNA. It comes back to the MRNA which is now attached to a ribosome and proteins are created.
The DNa is copied by the mRNA(messenger RNA) which brings it to the ribosomes. It is more complicated than that, I need to find a more complete one but if that can help. :)
Ribosomes are NOT located ON a protein. Ribosomes are organelles found in cells in/on which the cell synthesises (makes) proteins, using information that comes from the DNA in the cell's nucleus.

The nucleus is like the control center of the cell, everything comes in and out of the nucleus and the nucleus holds all the genetic data
