Question

The human genome has far fewer genes than previously thought. All of the following are ways that cells theoretically can increase the types of proteins they produce except


alternative splicing


transcription factors


compounding

Anticodons that are complementary to mRNA codons


I am totally lost here. I am thinking it is alternative splicing but am really only about 25% sure. Any takers?
