You are working on a research project involving a novel transcription factor that regulates gene expression specifically in muscle cells (called MUSC1). You have already done an experiment where you showed that the addition of MUSC1 to muscle cells in culture greatly increased the expression of both actin and myosin (contractile proteins in muscle cells). Answer the following questions below:
Is MUSC1 a general or regulatory transcription factor? Explain your answer.
What two specific components would you expect MUSC1 to have as part of its protein structure?
Briefly describe the two main ways in which MUSC1 could act to
stimulate transcription of actin and myosin
Describe an experiment that you could perform to demonstrate that
MUSC1 binds to the promoter/enhancer region of actin and myosin
genes.
A potential nuclear localization signal has been identified within
the protein sequence of the transcription factor MUSC1. What
experiments would you perform to demonstrate that this sequence is
both necessary and sufficient for nuclear localization?
MUSC1’s entry into the nucleus is regulated so that it only goes
into the nucleus to regulate the expression of contractile proteins
at the correct time. Describe one mechanism by which this type of
regulation can occur in the cell.

The clinical symptoms of two forms of galactosemia show radically different severity.
Although both types produce gastric discomfort after milk ingestion, deficiency of the transferase also leads to liver, kidney, spleen, and brain dysfunction and eventual death.
