The Seven Steps Of Protein Synthesis
Step One
DNA gets a signal that a particular protein needs to be made and unzips the part of the code.
Step 6
At every 3 base pairs, t RNA attaches a particular amino acid for the particular DNA
Step 7
Once the code has been completely read, a stop signal is given and protein synthesis is complete and the protein goes where it is needed

The 30S subunit consists of one molecule of 16S rRNA, and 20 different proteins of various sizes. This unit is responsible for formation of the initiation complex, performs the decoding of the genetic information, and controls the fidelity of codon-anticodon interactions. The large subunit consists of 2 RNA molcules: 23S and 5S rRNA, and 34 proteins. This subunit catalyzes the reactions of peptide bond formation and peptide release. It also provides the path for the nascent polypeptide chain through a tunnel.

Key step in protein synthesis revealed -- ScienceDaily

You can see that the ribosome is not an enzyme, but a ribozyme (catalytic RNA molecule) and no protein takes part in the reaction. The protein that comes close is L27, and it has been shown biochemically that it makes the ribosome slightly faster Probably it ishelping to correctly position P-site tRNA.

We can regard protein synthesis as a chemical reaction, and we shall take this approach at first

The Seven Steps Of Protein Synthesis - Prezi

Which amino acid that is going to be incorporated into the growing peptide chain is determined by the codon (a triplet of bases) on the mRNA (fig 2). Many amino acids have several codon options, so each amino acid can be incorporated by a set of different codons. For example, the amino acid lysine has two codons and serine has 6 different codons. Codons for the same amino acid tend to have the same nucleotides for the two first positions and only differ in the third position. Only two amino acids, tryptophan and methionine, have one single codon. The codon for methionine is also a start signal for protein synthesis. There are also several stop codons, which are used as a signal when the protein message is ending. These are decoded not by a tRNA but by a protein called release factor.

Now that we’ve described DNA and RNA, it’s time to take a look at the process of protein synthesis

What are the basic steps of protein synthesis? | Chemistry

The function of the ribosomes in the cell is to translate the genetic information in form of mRNA into proteins. The mRNA is transcribed from DNA using an enzyme called RNA polymerase. To do this, the ribosome requires the presence ofadaptor molecules, the so called transfer RNAs (tRNAs). The tRNAs are small RNA molecules with a defined 3D structure. The tRNAs are charged with the correct amino acid by specific enzymes called aminoacyl-tRNA synthetases. When correctly charged, they function as adaptors between a three-base mRNA codon and the corresponding amino acid.
