Alternative splicing: rearrangement of exons in the mRNA transcript in multiple patterns
Why can alternative splicing of messenger RNAs (mRNAs) be advantageous for eukaryotic organisms?
a) allows for smaller genomes than prokaryotes
b) decreases the average gene length in eukaryotes
c) increases the variety of proteins that can be produced
d) removes exons instead of introns from newly transcribed mRNA
e) allows exons from two different genes to be spliced into a new mRNA
