QUESTION 2 If you made a change in the DNA of a promoter sequence that inactivates the promoter, what would happen at the RNA level? O The DNA helicase would not be able to recognize and bind the DNA, so the RNA would not be made The mutation of the DNA would be carried through to the RNA sequence The RNA polymerase would not be able to recognize and bind the DNA, so no RNA would be made Nothing, because the RNA would be made as usual

The enormous complexity in initiating eukaryotic gene transcription seems at first glance to be wasteful. What is the most plausible reason for requiring so many different proteins to assemble on a large array of DNA sequences in order to initiate transcription? O The use of large numbers of proteins and regulatory sequences in DNA opens many possibilities for sophisticated combinatorial gene regulation O The need to open chromatin for transcription demands a much larger number of proteins and regulatory sequences in DNA O The use of large numbers of proteins and regulatory sequences in DNA is essential for alternative splicing of hnRNA in eukaryotes O The larger number of eukaryotic genes demands a correspondingly larger transcription apparatus than that of prokaryotes The larger size of eukaryotic cells demands a correspondingly larger transcription apparatus than that of prokaryotes
WHAT ELSE CAN I ADD TO THIS DISCUSSION In general, what is gene regulationand what are the consequences if this process goes awry? Gene regulation is the process used to control the timing, location and amount of genes expressed. The process is carried out by a variety of mechanisms, including regulatory proteins and chemical modification of DNA. It’s key to the ability of an organism to respond to environmental changes. If the gene regulation process goes awry, these alterations are called mutations and can accumulate over a lifetime. Errors in genes that control cell division can cause cancer and other genetic mutations to take place.

Alternative Splicing Possibilities Suppose exon 17 were deleted from the fast skeletal muscle troponin T gene (Figure 29.46). How many different mRNAs could now be generated by alternative splicing? Suppose that exon 7 in a wild-type troponin T gene were duplicated. How many different mRNAs might be generated from a transcript of this new gene by alternative splicing?
A scientist compares the promoter regions of two genes. Gene A’s core promoter plus proximal promoter elements encompasses 70bp. Gene B’s core promoter plus proximal promoter elements encompasses 250bp. Which of the scientist’s hypotheses is most likely to be correct? More transcripts will be made from Gene B Transcription of Gene A involves fewer transcription factors Enhancers control Gene B’s transcription Transcription of Gene A is more controlled than transcription of Gene B.
