Elsewhere in the paper,Chen et al.state that "BDNF is encoded by a complex gene with four well-characterized promoters that give rise to at least eight different mRNAs." What mechanism could account for the production of these different BDNF mRNAs from the same gene?
A)chromatin condensation control
B)alternative splicing
C)translational control
D)post-translational control

The production of different BDNF mRNAs from the same gene is likely due to alternative splicing, which allows for different combinations of exons to be included or excluded from the mRNA transcript. This results in different protein isoforms being produced from the same gene.
