In eukaryotes, functional messenger RNA molecules are made from

• exons spliced together after introns are removed
• introns spliced together after eons are removed
• exons spliced together with introns
• long pieces of RNA shortened by the Dicer enzyme

In messenger RNA, each codon specifies a particular

• nucleotide
• enzyme
• amino acid
• promoter

Carries the amino acid used to make a protein

• mRNA

• rRNA

• tRNA
