Explain what is happening at each numbered step in the diagram below

Steps are in protein synthesis:

1) m-RNA

2) ribosome / r-RNA

3) amino acid

4) t-RNA

5) peptide linkage.

The cytoplasm contains ribonucleoprotein particles called ribosomes, which are where protein synthesis takes place. In biology, the process of protein synthesis is crucial to cellular survival.  The process through which cells produce proteins is known as protein synthesis.

Function of these steps in protein synthesis -

1) m-RNA : The function of mRNA is to transport protein information from DNA in a cell's nucleus to the cytoplasm, or watery interior, where the machinery responsible for making proteins reads the mRNA sequence and converts each three-base codon into an amino acid that belongs in a protein chain that is expanding.

2) ribosome / r-RNA: The catalytic stages of protein synthesis—the joining of amino acids to form a protein molecule—are governed by the rRNA molecules. To represent this role, rRNA is frequently referred to as a ribozyme or catalytic RNA.

3) amino acid: Long thought to as little more than protein synthesis substrates, amino acids have lately been demonstrated to operate as modulators of intracellular signal transduction pathways frequently linked to growth-promoting hormones like insulin and insulin-like growth factor1.

4) t-RNA: The primary role of tRNA is to transfer amino acids to create polypeptides in the proper order. As a result, it aids in protein synthesis. Additionally, it serves as an adaptor molecule by connecting particular amino acids to the appropriate codons found in the mRNA molecules.

5) peptide linkage: Covalent bonds between two amino acids are known as peptide bonds. Proteins are large chains of amino acids that are created by living things via peptide bonds. In addition to providing structural support, initiating significant processes, and identifying chemicals in the environment, proteins have a variety of other activities.
