How can there be so many more proteins produced by our cells compared to the number of genes that we have?
A) RNA processing in the nucleus creates different messenger RNAs from the same original transcript.
B) Each protein is encoded by several genes.
C) Alternative splicing occurs in a small number of genes.
D) All of the mRNAs produced from a single pre-RNA will contain the same exons.
E) All of these are correct answers.
