2. A contract is said to be consummated, when everything to be done in relation to it, has been accomplished. It is frequently of great importance to know when a contract has been consummated, in order to ascertain the rights of the parties, particularly in the contract of sale.
A polyribosome (or polysome) is a complex of an mRNA molecule and two or more ribosomes that act to form polypeptide chains during active translation. Originally coined ergosomes in 1963, they were further characterized by Jonathan Warner, Paul Knopf, and Alex Rich.
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.
