When TMV-RNA is used for infection, the amino acid sequence of the coat protein of the progeny is the same whether the host is Zinnia or tabacco. This proves that the genetic code is

TMV infects a variety of plants, including Zinnia and tobacco. When TMV-RNA is used for infection, the amino acid sequence of the coat protein of the progeny is the same whether the host is Zinnia or tobacco. This proves that the genetic code is :-

A genetic unit that codes for the amino acid sequence of a complete plypeptide chain is most closely related to a :

RNA responsible for directing proper sequence of amino acids in protein synthesis is:

A single amino acid is often coded by more than one triplet code. In most of the cases the first two bases are the same but the third base is different. This feature of the genetic code is called :
