Ribosomes

Postby Tamsicle » Sat May 21, 2005 1:51 pm

Ribosomes: Can someone please tell me where they are synthesised? They're proteins, right? I know they're involved in protein synthesis, but what composes the initial proteins which allow the synthesis of other proteins to take place? Without ribosomes, how can you make more organelles involved in the synthesis of more?! And when they bind with mRNA, how does the mRNA 'know' how to get to the endoplasmic reticulum region or loose ribosomes within the cytoplasm? Is it their chemical properties?

Ribosomes are syntesized in the nucleus, the structure at which this occurs is the nucleolus. When the ribosomes are produced, they move out of the nucleus to the rough endoplasmatic reticulum. More information here http://cellbio.utmb.edu/cellbio/nucleus3.htm
