Chapter 17.2, Problem 1CC
MAKE CONNECTIONS → In a research artide about alkaptonuria published in 1902, Garrod suggested that humans inherit two "characters" (alleles) for a particular enzyme and that both parents must contribute a faulty version for the offspring to have alkaptonuria. Today, would this disorder be called dominant or recessive? (See Concept 14.4.)

E27. A cloned gene fragment contains a regulatory element that is recog-
nized by a regulatory transcription factor. Previous experiments have
shown that the presence of a hormone results in transcriptional acti-
vation by this transcription factor. To study this effect, you conduct a
electrophoretic mobility shift assay and obtain the following results:

Explain the action of the hormone.
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

Question:-
Many types of breast cancer have chromosomal translocation mutations. What scenario best describes, what occurs during this type of mutation, causing cells to proliferate abnormally?
Chromosomal translocations may place the gene downstream near the promoter region, therefore causing over-expression of the gene
The gene may be placed in the transcription start site, downstream of the gene, initiating transcription by recruiting polymerase II
Translocation mutations will initiate the transcription of mRNA in the cytoplasm of the cell catalyzing protein synthesis.
Chromosomal translocations can sometimes place a gene under the control of a powerful enhancer, upstream.

In the technique of DNase I footprinting, the binding of a protein to a region of DNA protects that region from digestion by DNase I by blocking the ability of DNase I to gain access to the DNA. In the DNase I footprinting experiment shown here, a researcher began with a sample of cloned DNA 400 bp in length. This DNA contained a eukaryotic promoter for RNA polymerase II. The assembly of general transcription factors and RNA polymerase II at the core promoter is described in Chapter 12 (see Figure 12.14). For the sample loaded in lane 1, no proteins were added. For the sample loaded in lane 2, the 400-bp fragment was mixed with RNA polymerase II plus TFIID and TFIIB. 2 400 350 250 175 50 Which region of this 400-bp fragment of DNA is bound by RNA polymerase II and TFIID and TFIIB? || III ||| | ||||arrow_forward

- Mating Ste12 Tec1 Budding 17. (8 points) Scientists are studying the transcription factors Ste12 and Tec1. They have found that when ste12 binds to one part of the genome alone it activates the transcription of genes important in mating pheromones. They also found that when Tec1 binds to another part of the genome alone it activates the transcription of cellular budding genes. Lastly, they found that in another part of the genome, Ste12 and Tec1 both bind to the DNA, they activate the transcription of genes that control the formation of filaments. a) These proteins bind to enhancers.
