The functions of all there cell organelles are differant in their own way , but together they perform one function called protein synthesis.
The central dogma of mol biology is DNA-mRNA-Proteins
The nucleus contains double stranded DNA which is used to sy nthesize a single stranded mRNA by a process called the transcription. This mRNA is transported from the nucleus into the cytoplasm. The mRNA is used to synthesize proteins, bya process called translation. The translation process requires tRNA, aminoacids and ATP. Proteins can be synthesized inthe cytoplasm or can also be done the ER. THis requires specialized particles called ribosomes. They help in protein translation. Protein translated on the ribosomes on the surface of the ER is targetted from the ER into various cell compartments like lysosomes, plasma membrane. ER helps to target the protein into various compartments of the cell.

They are small parts of cells that are involved in protein synthesis. The DNA is copied in the nucleus. The copy moves out of the nucelus to the ER where it binds to a ribosome and this dictates the order of amino acids that are going to make the resulting protein. The protein is a chain of these molecules and the chain then folds up to make up a protein. Hope that helps you. I used to leave my homework to the last minute, too. LOL.

I assume you mean the ribosome.
It's your homework (I assume) so you have to come up with the sentence but here's a hint: look up protein synthesis, you'll want to include the words transcription and translation.

I do not know the answer to your question, but have been using wikipedia.org, www.internethealthlibrary.com and www.healthnewsflash.com, for all my medical research purposes with great success! I hope this helps, if nothing else it may refer you to further links that might be of use to you.
Good luck.

Do you really mean 'rib' or 'ribosomes'? I would suggest you look in a textbook under cells or subcellular organelles and find out.

Angel, you're meant to be studying so you learn, not using Yahoo Answers to AVOID learning!

Very long and complex sentences.

The answer to this question is that it is an incomplete question and therefore unanswerable!
