<u>Translation:</u> process of protein formation is called translation .
In the process of translation, a cell reads information from a molecule called a messenger RNA and uses this information to build a protein. Translation involves “decoding” a messenger RNA and using its information to build a polypeptide, or chain of amino acids
.
Translation involve three major steps
• Initiation ("beginning"): in this stage, the ribosome gets together with the mRNA and the first tRNA so translation can begin.
• Elongation ("middle"): in this stage, amino acids are brought to the ribosome by tRNAs and linked together to form a poly peptide chain.
•Termination ("end"): in the last stage of translation, the finished polypeptide is released to go and do its job in the cell.
<u>Organelles involve in translation:</u>
Ribosomes: main process of translation occour at ribosomes.
Rough endoplasmic reticulum: ribosomes are located on rough endoplasmicreticulum .it bound proteins in the vesicles.Vesicles containing proteins are budded off into cytoplasm and move toward golgi apparatus for further modification .
Golgi apparatus: synthesisezed proteins are not functional . In golgi apperatus they are further modefied and processed and stored for a short time and then released toward destination.
