Where does translation take place in the cell?

Where does translation take place in the cell?

Where Translation Occurs. Within all cells, the translation machinery resides within a specialized organelle called the ribosome. In eukaryotes, mature mRNA molecules must leave the nucleus and travel to the cytoplasm, where the ribosomes are located.

Does translation occur in the cytoplasm or rough ER?

Recall that in eukaryotes, translation can occur either in the cytoplasm or on the rough ER. Membrane and secretory proteins are synthesized in ribosomes on the rough ER whereas the cytosolic proteins are synthesized in ribosomes in cytoplasm. The start codon for both prokaryotic and eukaryotic translation is AUG.

Does translation occur in the rough endoplasmic reticulum?

Translation occurs on ribosomes in the cytoplasm or rough endoplasmic reticulum.

Where does the majority of translation occur?

The majority of these processes take place in the cell cytoplasm or in the endoplasmic reticulum. In eukaryotes, translation occurs entirely separately from transcription, because pre-mRNA script created in transcription must be modified before its translated.

What happens when translation takes place?

Translation is the process by which a protein is synthesized from the information contained in a molecule of messenger RNA (mRNA). Translation occurs in a structure called the ribosome, which is a factory for the synthesis of proteins. …

What is the result of translation?

The molecule that results from translation is protein — or more precisely, translation produces short sequences of amino acids called peptides that get stitched together and become proteins. During translation, little protein factories called ribosomes read the messenger RNA sequences.

Where does translation take place? ribosome (Translation, or protein synthesis, occurs at the ribosome.) Where does translation take place? -Golgi apparatus -Ribosome -Endoplasmic reticulum -Nucleus

Where does the translation of tRNA take place?

The three binding sites for tRNA on ribosome are called the A, P, and E sites. Ribosomes also contain enzymes that catalyze the reaction that binds amino acids together into a polypeptide chain. Translation itself can be broke down into three steps: initiation, elongation, and termination.

When does the last step of translation take place?

That is the role of the last step of translation, called termination. Termination of translation mechanisms happens once a stop codon (UAA, UAG, UGA) enters the A site. When a stop codon enters the A site, it is recognized not by tRNA, but special proteins called release factors.

What kind of machinery is needed for translation?

Translation is a complex process that requires some specialized machinery. Two types of molecules are involved in the translation process: tRNA and ribosomes. tRNAs (“transfer” RNAs) are molecules that bridge the gap between codons in mRNA and the amino acids they specify.
