Chapter 12.3, Problem 1CR
Summary Introduction
The animal genome contains both exons (coding regions) and introns (non-coding regions). If the cloned gene possesses introns, it will affect the production of a correct protein molecule in a host. Hence, before cloning the DNA sequence must be modified (DNA sequence must contain only exons).

What are the evolutionary advantages associated with stress-induced mutagenesis?
In the bacteriophage T7 system used to express recombinant proteins, the gene of interest is fused to T7 promoter and T7 RNA polymerase is separately cloned into the same cell. What is the main reason this system uses T7 RNA polymerase instead of relying on the bacterial RNA polymerase?
To restrict the expression of bacterial protein expression
To enhance the amount of recombinant protein expression
To enhance the expression of bacterial protein expression
To restrict the amount of recombinant protein expression
To enable the expression of T7 viral protein expression
Gene expression can be disrupted by techniques such as homologous recombination and RNA interference. What is the functional difference between these two methods in terms of the ultimate effect on gene expression? Why might homologous recombination or an alternative genome-editing method (e.g., CRISPR/Cas9) be preferred over RNA interference?
