【 摘 要 】
It has long been known that there is remarkable affinity between 5 S and 18 S rRNA from wheat embryos. Experimental evidence has failed to support the proposition that the extensive complementarity which exists between 3'-terminal regions of the large-subunit (5 S) and small-subunit (18 S) rRNA is involved in uniting the subunits of the ribosome. Alternatively, it is suggested that the degree of complementarity between the 3'-terminal regions of wheat-embryo 5 S and 18 S rRNA may have significance at the level of the genome. It is suggested that common sequences in the 3'-terminal coding regions of 5 S and 18 S rRNA genes may serve to co-ordinate the expression of 5 S rRNA genes with the expression of the remainder of the (18 S/ 5.8 S/26 S) rRNA genes.
