Proteins are necessary for the cells to perform cellular functions. Ribosomes are the cellular component that make proteins from all amino acids. Ribosomes are made from complexes of RNAs and proteins. The number of ribosomes in a cell depends on the activity of the cell. Ribosomes are freely suspended in the cytoplasm or attached to the endoplasmic reticulum forming the rough endoplasmic reticulum. On an average in a mammalian cell there can be about 10 million ribosomes.
When the ribosomes are attached to the same mRNA strand, this structure is known as polysome. The existence of ribosomes is temporary, after the synthesis of polypeptide the two sub-units separate and is reused or broken up. Amino acids are joined by the ribosomes at a rate of 200 per minute . Therefore small proteins can be made quickly but two or three hours are needed for proteins which are as large as 30,000 amino acids.
The ribosomes present in the prokaryotes function differently in protein production than the ribosomes of the eukaryote organisms. The ribosomes of bacteria, archea and eukaryotes differ significantly from each other in structure and RNA sequences. The differences in the ribosomes allows the antibiotc to kill the bacterial ribosome by inhibiting the activity of the bacterial ribosomes, the human ribosome sramin unaffected. The ribosomes of the eukaryotic cellas are similar to the ribosomes of the bacterial cells, showing the evolutionary origin of the organelle.
