Question
Chapter 4.3, Problem 1BC
Summary Introduction
To analyze:
Theeffect of alternative splicing on the structure and function of the cell.
Introduction:
The methods of controlling the part of DNA to be transcribed are referred to as gene expression. The gene expression is regulated by binding of the protein to specific sites on the DNA molecule and synthesizing regulator gene that encodes for the synthesis of the molecule known as the repressor molecule.

Think of different possible outcomes if splicing errors occur.arrow_forwardCan I have a detailed explanation on how alternative splicing might affect metabolism. Thank you!arrow_forwardYou are a research scientist working in genetic engineering. You create a piece of DNA that you want to express in E. coli, a prokaryote. This piece of DNA (represented by the schematic in the figure) consists of a bacterial promoter, a ribosome binding sequence (RBS), a eukaryotic gene and a terminator sequence. Do you think that this piece of DNA would be expressed if placed into an E. coli cell that contains all the machinery needed for gene expression? Fully motivate your answer.arrow_forward
- . In bacterial genes, as soon as any partial mRNA transcriptis produced by the RNA polymerase system, the ribosome assembles on it and starts translating. Draw a diagram of this process, identifying 5′ and 3′ ends of mRNA,the COOH and NH2 ends of the protein, the RNA polymerase, and at least one ribosome.

Let’s say that you have incredible skill and can isolate the white and red patches of tissue from the Drosophila eyes shown in Figure 12-24 in order to isolate mRNA from each tissue preparation. Using your knowledge of DNA techniques from Chapter 10, design an experiment that would allow you to determine whether RNA is transcribed from the white gene in the red tissue or the whitetissue or both. If you need it, you have access to radioactive white-gene DNAarrow_forward
- Which of the following is likely associated with the mRNA processing step of alternative splicing? 1. A gene is discovered to encode for two different proteins one protein has 46 amino acids and the other protein has 86 amino acid 2. A gene has 7 exons. one processed mRNA transcript from this gene contains exons 3, 4, 6 and 7. a second process mRNA transcript from this gene contains exons 2, 3, 5, and 7 3. The open reading frame of a gene contains 90 nucleotides but the translated polypeptide contains only 29 amino acids 4.

A mutant strain of Salmonella bacteria carries a mutation of the rho protein t hat has full activity at 37°C but is completely inactivated when the mutant strain is grown at 40°C. (Question # 21; Chapter 8-Genetics: An Integrated Approach). Speculate about the kind of differences you would expect to see if you compared a broad spectrum of mRNAs from the mutant strain grown at 37°C and the same spectrum of mRNAs from the strain when grown at 40°C. Are all mRNAs affected by the rho protein mutation in the same way? Why or why not?arrow_forward
