The -10 and the -35 boxes found in bacterial gene promoters function to:
A)recruit DNA polymerase activity for DNA replication before cell division.
B)activate transcription at the -35 region of a gene.
C)orient RNA polymerase at a gene's transcription start site.
D)identify the boundaries between introns and exons.
E)identify the boundaries for DNA unwinding during transcription.

Question

Quizplus · Accepted Answer

The -10 and -35 boxes are regions of DNA found in bacterial promoters that are recognized by RNA polymerase, which orients itself at the transcription start site of a gene. This orientation allows for proper initiation of transcription.

Therefore, option C is the best choice.
