The steps for protein synthesis are:
-Unziping
-Transcription
-Translation
-Elogation
-Termination
1) Unziping: DNA double strand unwinds to expose a sequence of nitrogenous bases (4 the base pairs along a length of DNA separate, exposing binding sites of the bases);
2) Transcription: A copy of the DNA strand is made creating a RNA strand (1 RNA bases bind to DNA bases);
3) The exit of the mRNA made up in the second step to the cytoplasm (5 An RNA copy of the gene leaves the nucleus);
4) Translation: (2 amino acids are brought to the RNA, the mRNA and the tRNA meet to translate the nitrogeneous bases in amino acids);
5) Elogation and Termination: (3 The amino acid string folds and form a protein) the protein information from the mRNA, translated with the help of the tRNA is used for the protein synthesis in the cells cytoplasm.
Therefore, the final order for the question is: 4-1-5-2-3
