Using Genetic Engineering Techniques, You Remove the Sequences That Code

question 10

Multiple Choice

Using genetic engineering techniques, you remove the sequences that code for the ribosome-binding sequences of the bacterial LacZ gene.The removal of these sequences will lead to

• A)more LacZ protein being produced due to faster ribosome movement across the LacZ mRNA.
• B)transcriptional repression, resulting in fewer mRNA molecules being produced from this gene.
• C)a longer half-life for the LacZ mRNA.
• D)translational inhibition of the LacZ mRNA.
