RNA Splicing: involves removal of introns and recombining exons
• introns (intervening sequences): do not code for proteins; usually contain regulatory regions for transcription
• exons (expressed sequences): code for proteins
Use the diagram provided to select the correct statement regarding RNA splicing.
A) only coding introns are spliced together to make finished mRNA
B) a protective cap is put on the 5' end
C) a string of adenines is put on the 3' end
D) only coding exons are spliced together to make finished mRNA
