The bacterial holoenzyme binds
a. only to the template strand
b. only to the non-template strand
c. to both strands
Homework Answers
to both strands.
because the holoenzyme is the part of RNA polymerase. It binds to the -10 to -20 consensus sequence in the DNA and leads to unwinding the double stranded DNA. In this way, it creates a bubble formation which provides the appropriate place for the activity of RNA polymerase to synthesise the RNA by the process of transcription.

Note that one of the two halves of the DNA molecule is labeled template strand and the other is the non-template strand. In protein synthesis, the RNA polymerase reads the template strand and uses it to make mRNA, filling in complementary bases. The mRNA then closely resembles the non-template strand. a. In what two significant ways do the non-template strand and the mRNA differ?
