Question
Chapter 8, Problem 6Q
Summary Introduction
To explain: The expected results of the given experiment.
Concept introduction:
Transcription process marks the beginning of gene expression. Transcription factors are the proteins that function in transcribing DNA to mRNA. Enhancers are distal control elements located away from the transcribing gene. The control elements of enhancers are short DNA
Given:
The experiment is designed in Professor Q’s laboratory to determine how far an enhancer be moved from the promoter region of the straight spine gene and still initiate transcription. In order to determine this, the numbers of nucleotide pairs are varied between promoter and enhancer sites. The graph shows the data after measuring the production of straight spine mRNA.

Explain the impact William B. Travis has made.
If PCR was performed on the fragment of DNA shown below using "5'-TAGG-3" and "3'-TCTA-5'" as the primers, how many base pairs long would the PCR product be? To help with this, remember the antiparallel structure of DNA and that primers are complementary and antiparallel to the target sequence that they bind to. Hint: Check out the 5' and 3' labels....they are important!
