Ribosome - Biology-Online Dictionary

The newly formed polypeptide chain undergoes several modifications before becoming a fully functioning protein. Proteins have a . Some will be used in the , while others will remain in the or be transported out of the . Many copies of a protein can be made from one mRNA molecule. This is because several can translate the same mRNA molecule at the same time. These clusters of ribosomes that translate a single mRNA sequence are called polyribosomes or polysomes.

Together, the evidence was convincing. “What all of this was saying was that we were getting a totally unprecedented mechanism for ribosome-mediated protein synthesis,” Weissman says. “Every other time that people have seen the ribosome make or extend proteins, it's been a messenger RNA that's responsible for bringing the tRNA to read out the genetic code, and you need a large and a small subunit. Here we had synthesis with no messenger RNA and no small subunit. And a protein, Rqc2, was responsible for recognizing and recruiting these specific tRNAs.”

Translation occurs in the . After leaving the , mRNA must undergo several modifications before being translated. Sections of the mRNA that do not code for amino acids, called introns, are removed. A poly-A tail, consisting of several adenine bases, is added to one end of the mRNA, while a guanosine triphosphate cap is added to the other end. These modifications remove unneeded sections and protect the ends of the mRNA molecule. Once all modifications are complete, mRNA is ready for translation.
