Answer #1

Termination sequence of DNA which provide binding site for termination factor . It is present at 5'end and is called downstream end . As we already know RNA polymerase can do the function of synthesis and is unable to terminate replication . So if termination sequence is not present at the opposing polarity towards the replication terminus of the chromosome the synthesis will be continued to stop replication of DNA rho factor is loaded before termination at termination sequence .
