What would happen if alternative splicing did not occur?
A) The E. coli genome would contain many fewer genes.
B) There would be little correlation between the complexity of organisms and genome size.
C) There would be many fewer genes devoted to metabolism in Arabidopsis and yeast.
D) The human genome would likely contain many more genes.
E) Fewer mutations would occur in a human cell's lifespan.

Question

Alternative splicing allows for multiple protein isoform production from a single gene, increasing proteomic diversity. Without alternative splicing, the human genome would not be able to produce as many proteins as it currently does, and therefore would require more genes to maintain the same level of proteomic diversity.
