Question
Chapter 19, Problem 9TYPSS
Summary Introduction
Introduction:
Enhancers are a short sequence of the DNA (deoxyribonucleic acid) that is capable of binding to the proteins in order to elevate the occurrence of the transcription process of a specific gene. The promoter is a region, which begins the transcription process of a gene.

Coli growth even when fed Red Bull. You find that each class of mutations localize separately to two separate regions. For those mutations that prevent growth even when fed Red Bull are all clustered upstream of the core promoter around -50 bp. For those mutations that are able to constitutively activate the operon in the absence of Red Bull are all located between the coding region of sleep and wings. Further analysis of each DNA sequence shows that the sequence upstream of the promoter binds the protein wings and the region between the coding sequence of sleep and wings binds the protein sleep. When the DNA sequence of each is mutated, the ability to bind DNA is lost. Propose a final method of gene regulation of the Up Lateoperon using an updated drawn figure of the Up Late…arrow_forward
- What would be the effect of moving the insulator shown in Figure 17.8 to a position between enhancer II and the promoter for gene B?arrow_forwardOne of the main lessons of this chapter is that several bacterial genes are often transcribed from a single promoter into a large multigene (polycistronic) transcript. The region of DNA containing the set of genes that are cotranscribed, along with all of the regulatory elements that control the expression of these genes, is called an operon. a. Which of the mechanisms in the following list (i-vi) could explain differences in the levels of the mRNAs for different operons? Different promoters might have different DNA sequences Different promoters might be recognized by different types of RNA polymerase The secondary structures of mRNAs might differ which will influence the rate at which they are degraded by ribonucleases. In an operon, some genes are farther away from the promoter than other genes The translational initiation sequences at the beginning of different open reading frames in an operon might result in different efficiencies of translation Proteins encoded by different genes…arrow_forwardSuppose you are studying the regulation of a gene involved in the metabolism of two nutrients, Llamasin and Alpacalon, in bacteria.
