In this paper, the study of sum signed graphs is continued. The balancing and switching nature of the graphs are analyzed. The concept of $rna$ number is revisited and an important relation between the number and its complement is established.
Keywords: balanced signed graph, $rna$ number, $rna$ complement number.
