Ribosomes

From sciarIDnet | wiki

Ribosome exist in all living cells they are smaller than organelles so they can only be seen by an electron microscope. Depending on the cell there can be a few million ribosomes or a few thousands. They are most active in brain cells.Ribosomes translate the RNA which is very much like DNA, DNA comes from RNA . The RNA is divided into two structure the mRNA(genetic code), the tRNA(building blocks) ; the mRNA gives the template of the cellular DNA to the ribosome so it can build a specific protein, this is the initial step because the rRNA is a passive template, so the initiator tRNA comes to the small ribosome structure and brings the building block which is the amino acid. The tRNA binds in three sites inside the ribosome and initiates it, the tRNA leaves or exits and the large subunit of the ribosome approaches and connects to the smaller subunit where the initiation occurred. The ribosome complete joint structure contains and entry site and an exit site. The tRNA then starts bringing amino acids to the ribosome, the ribosome takes the amino acids and with it creates new born proteins that then go out of the cell and into most parts of our body. Each ribosome can produce hundreds of proteins and the ribosomes usually work together.

In conclusion the ribosome translates or decodes the RNA specifically the mRNA to produce proteins. So this “birth” or code translation that leads to creation of protein is very powerful because they exist in specific sites, in very small places in our cells the magic of creation is constantly happening by a translation mechanism still in its totality mysterious to scientist.
