Each corresponding amino acid is added to the growing chain and linked via a bond called a peptide bond. Elongation continues until all of the codons are read. Since there are no tRNA molecules that can recognize these codons, the ribosome recognizes that translation is complete. The new protein is then released, and the translation complex comes apart.

In order to do that, they have to produce the same constituents for the new cell that is to be made. The only way to do that is by producing proteins. The proteins are produced in the process that is called protein synthesis. The first step is in the nucleus where a particular gene is being expressed so it enables all protein factors to come and to replicate that part of a chromosome.
This is finished when mRNA, the same single-stranded genetic code of a particular gene, is formed. This is transcription. Right after that, the mRNA enters the cytoplasm through nuclear pores.

The process of translation can be seen as the decoding of instructions for making proteins, involving mRNA in transcription as well as tRNA.
