Translation is the second process involved in protein synthesis. It is the process whereby protein is synthesized from an mRNA molecule. Initially, the information contained in the DNA molecule is transcribed into RNA molecule in the nucleus of eukaryotic cells.
The mRNA molecule then leaves the nucleus and attaches to a complex of RNA and protein called RIBOSOME, which is found floating freely in the cytoplasm or attached to Endoplasmic Reticulum. The Ribosome is an organnelle regarded to be the site of protein synthesis.
Hence, translation starts when the mRNA molecule attaches to the Ribosome in the cytosol of the cell.
The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells
