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?

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.

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

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?

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

What is/are the function(s) of the 5’ cap and the Poly-A-tail? Select all that apply

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

In mature mRNA, exons have been spliced out and introns will be translated into protein

Female twins who grew up in the same household go off to college. After four years, one of them develops schizophrenia, the other stays mentally healthy. What phenomenon can explain this development?

Rho- dependent/independent transcription termination is present solely in bacteria.
