These results identify a transcriptional regulatory element associated with a nuclease- hypersensitive site in the pol gene of HIV-1 and suggest that its activity may be controlled by a complex interplay of cis- regulatory elements .
 DNA: pol gene; DNA: regulatory elements; DNA: nuclease- hypersensitive site; DNA: transcriptional regulatory element; DNA: hypersensitive site
