Statement (2) is true, as a phosphate group is indeed associated with the 5' end of a nucleic acid. Statement (1) is false, as rRNA does not contain exons and introns. Statement (3) is also false, as both AMP and dAMP contain the same sugar subunit. Therefore, only two out of the three statements are true.
