The -10 and -35 sequences are recognized by: A.) 16S rRNA of the ribosomal small subunit B.)Sigma factor of RNA polymerase C.) The initiator tRNA D.)23S rRNA of the ribosomal large subunit E.)None of these F.)Initiation factor 3

Solution

The correct answer is

B) Sigma factor of RNA polymerase

The DNA sequence of the promotor region is recognized by the requisite RNA polymerase. The best characterized bacterial promotor are those of bacterium E.coli that are recognized by Sigma factor 70.
