The histone H3 lysine 9 acetylation (H3K9ac) epigenetic modification regulates transcription by creating a relaxed chromatin state at the promoter.  What is the primary mechanism by which histone acetylation facilitates the relaxation of the chromatin structure?

Describe three ways in which eukaryotic transcription is different than prokaryotic transcription.

During transcription, the RNA polymerase II enzyme uses the template strand to synthesize the pre-messenger/nascent RNA transcript. The RNA polymerase reads the template _____ and synthesizes the RNA transcript ______.

The mutation rate in nonhuman organisms is the:

Describe three different types of alternative splicing and how each one affects the resulting mRNA spliceform?

A geneticist discovers a previously unknown variant in gene X that is associated with hair loss in men.  It is a coding variant that changes a single amino acid of the protein sequence. Genetic testing of 1,000 male students at Texas A&M University indicates that the variant is present in 200 of the participants. Is this variant considered a mutation or a polymorphism?

The primary structure of a protein is determined by: 

The histone code is described as the sum of complex patterns and interactions of histone modifications.  The histone code is largely involved in:

Deletion of an exon will often cause a loss-of-function of the protein; however, there are instances when the deletion of an exon is still capable of producing a functional protein.  This can happen when the:

In autotrophic bacteria, where is chlorophyll located?
