Problem: Why can alternative splicing of messenger RNAs (mRNAs) be advantageous for eukaryotic organisms?a) allows for smaller genomes than prokaryotesb) decreases the average gene length in eukaryotesc) increases the variety of proteins that can be producedd) removes exons instead of introns from newly transcribed mRNAe) allows exons from two different genes to be spliced into a new mRNA
