Question

Refer to the figure below, which deposits a typical prokaryotic gene, for the following four questions. The sequences labeled as "regions A-D" include both strands over the area highlighted Region A Region B Region C Region D 5'hellip GCCATIAGTTAGCCC A AT AT ATGAT AG A AGC ACTCT ACT GTC A ACT C AAT AGGT CC ACGC hellip 3' hellip C GGT A ATC AATCGGGTT AT AT ACT ATCTTCGTGAG ATG AC AGTTG AGTT ATCCAGGTGCG hellip +1 -10 -35 Which region of the DN A sequence will most likely be transcribed into RNA? Region A Region B Region Region D All of the above

Explanation / Answer

Answer is region D.

Because, -10 upstream is the TATA box where RNA polymerase enzyme binds (TATA box is the promoter). Upstream to TATA box for about 35 bases, i.e., -35 is the site where transcription bubble formed and RNA synthesis begins. So region D is the answer.
