I don't get you. You have studied animal science - I suppose this has something to do with biology... you are on your master thesis, so you already have a bachelor... and you will make us believe that you are unable to read a book on cell or molecular biology or the Wikipedia article (at least as a startng point)? Or are you simply too lazy to gather and process this information by yourself?
Look up for "protein biosynthesis", then possibly come back and ask a more specific questions about the things you don't understand from the sources that are available to you.
Sorry for this rude answer, especially if I got it wrongly. But to me it really looks as if you are just asking to be pampered...
thank's about your respon Mr. Jochen Wilhelm.,.,I realized less read books and journals, because I have not well to understand English language. in the future I will try to read a lot of book and This may be a lesson for me.
