Ribosomes in Translation

Translation takes place in this cell organelle?

• Translation takes place in two cellular locations. The mRNA and tRNA meet in the cytoplasm and create the polypeptide chain and then the creation of the protein happens in the ribosome.

• Translation takes place in two cellular locations. The mRNA and tRNA meet in the nucleus and create the polypeptide chain and then the creation of the protein happens in the ribosome.

• Translation takes place in two cellular locations. The mRNA and tRNA meet in the mitochondria and create the polypeptide chain and then the creation of the protein happens in the cytoplasm.

• Translation takes place in two cellular locations. The mRNA and tRNA meet in the endoplasmic reticulum and create the polypeptide chain and then the creation of the protein happens in the lysosome.
