The following DNA strand is used as a template for transcription: 3’ CGTAGGAATA ‘5 What is the corresponding RNA strand that will be produced?

A new protein is discovered by Julian. Julian notes this protein binds several thousand base pairs upstream of the Gene 1, and when it binds it decreases the transcription rate of Gene 1. What is the most possible identification of this protein?

The regulatory gene of a negative repressible operon encodes a _____ which requires a _____ in order to turn transcription OFF.

Which of the following molecular processes leads to epigenetic changes? Select all that apply.

Which of the following molecules is the inducer of the lac operon?

Determine the corresponding mRNA sequence produced in transcription given that the sequence provided is the non-template strand: 5’-AGCATACAGCAGACCGTTGAA-3’

One possible mutation within the lac operon is the mutation of the operator. When this happens, the repressor is unable to bind to the operator. How will this affect transcription?

Would transcription occur in lac operon, if lactose is absent and the mutation in the repressor is lacI-?

What would be the result of the addition of a nucleotide to the consensus sequence of an intron? The new nucleotide would be added in between the GG splice site.

Imagine you have the following operon that includes the genes that encode enzymes A, B, and C, which are required for the biosynthesis of molecule X into Y in most bacteria.  The product of gene M regulates gene expression in this cell. When there is a high level of the M product, you do not detect any levels of A, B, and C enzymes but when there is a low level of the M product you detect higher levels of the enzymes. Thus, the product of the M gene is a:
