Technically they are two separate units. The poly(A) sequence generally promotes transcript stability or degradation in eukaryotes and prokaryotes respectively. While the SV40 sequence is a terminator sequence that signals the end of a transcriptional unit. Terminator sequences also have a role in RNA processing and stability.
