Question
Chapter 30, Problem 9P
Interpretation Introduction
Interpretation:
The reason for 100-fold larger rate for a protein identifying a specific position along a DNA molecule should be determined.
Concept introduction:
DNA synthesis can be defined as the process by which the deoxynucleic acids such as adenine, thymine, cytosine, and guanine are associated together to form DNA.

RNA polymerase from E. coli (core enzyme alone) has all of the following properties except:
a)requires all four ribonucleoside triphosphates and a DNA template.
b)can extend an RNA chain and initiate a new chain.
c)recognizes specific start signals in DNA.
d)produces an RNA polymer that begins with a 5'-triphosphate.
e)is required for the synthesis of mRNA, rRNA, and tRNA in E. coli.
True or false?: The CTD is responsible for mRNA-processing steps that are specific for mRNA and not for other forms of RNA. Explain why you chose true or false.
Remember remove the introns! All introns start with GT and end with AG.
