Question

How ribosomes make proteins

Answer 1

The process of making proteins is quite simple. need an amino acid. Another nucleic acid that lives in the cell is transfer RNA. tRNA is bonded to the amino acids floating around the cell. With the mRNA offering instructions, the ribosome connects to a tRNA and pulls off one amino acid. The proteins and nucleic acids that form the ribosome sub-units are made in the nucleolus and exported through nuclear pores into the cytoplasm. The two sub-units are unequal in size and exist in this state until required for use. The larger sub-unit is about twice as large as the smaller one. The larger sub-unit has mainly a catalytic function; the smaller sub-unit mainly a decoding one. In the large sub-unit ribosomal RNA performs the function of an enzyme and is termed a ribozyme. The smaller unit links up with mRNA and then locks-on to a larger sub-unit. Once formed ribosomes are not static organelles. When production of a specific protein has finished the two sub-units separate and are then usually broken down. Ribosomes have only a temporary existence.

Answer 2

Ribosomes provides the site for the synthesis of protein, where mRNA gthers up the message for the synthesis of protein, this message is then translated by tRNA and the process begins
