Which step is shown?

The step is transcription.

Transcription is the process by which the RNA is produced from ribonucleotide polymerisation taking DNA as the template.

The DNA is the genetic molecule of the living organisms. This DNA stores the genetic information and passes them to the offsprings by means of reproduction. This DNA has the information about the production of the proteins that is manifested by the central dogma theory.

The enzyme DNA dependent RNA polymerase acts on DNA which brings the ribonucleotides and polymerises them according to the complementary template supplied by DNA.

Here the step of transcription are mentioned where we can see a RNA polymerase producing a part of the RNA.

The protein synthesis stage shown above is called "Initiation".

Explanation:

Initiation is where the preparation of the molecules responsible for the origin of the protein molecule takes place. For this stage, the ribosomes must be ready, as they will be essential for this moment. It is also necessary that the mRNA is already formed because it is he who will give the instructions for protein formation. Last but not least, several molecules of different tRNA are needed, which can bind to amino acids and take them to the robosomes for the proteins to be manufactured.

The process begins when the tRNa binds to the amino acid methionine and takes it to the small subunit of the ribosome. After that, the tRNA already bound to methionine and the small subunit of the ribosome, binds to the 5 'end of the mRNA and moves towards the 3' end, while adding other amino acids, forming a chain of amino acids, the protein
