Answer #1

During the transcription process, the enzyme RNA polymerase starts the process of RNA transcription. It binds to the promoter site and starts the process. The promoter site is AT-rich region and is located at -10 and -35 upstream from the start site of the gene. In this case, this site at which this enzyme bind is the promoter sute.

The answer is A.

    The gene machine program shows you what happens when lactose is present in E. coli, and how the lac operon is under negative control. However, the lac operon is also under positive control from a protein called CRP, eAMP Receptor Protein. The absence of the lac repressor is essential but not sufficient for effective transcription of the lac operon. RNA polymerase also depends on the presence of CRP. Like the lac repressor, which can bind to the DNA and lactose....

    In rho-dependent transcription termination: the formation of a hairpin in the transcribed mRNA causes RNA polymerase to pause, facilitating termination. rho binds the mRNA, and when it makes contact with RNA polymerase, it assists with the removal of the mRNA from the DNA template. the rho factor binds to the -10 consensus sequence located in the promoter region to terminate transcription. a site within the poly(A) tail is cleaved which signals termination. the 3' untranslated region (3" UTR) is synthesized....
