This molecule carries amino acids to the ribosomes to make proteins.
The first isolated aptamers were made of these molecules. These are the molecules that most frequently form stem loops or "hairpins." Amounts of this molecule may be detected and quantified by a Northern blot. One type of this molecule has catalytic capabilities and forms the non-protein part of a snRNP  (" snurp ") . Another type of this molecule is synthesized in the nucleolus and forms the non-protein part of (*)  ribosomes. This molecule carries amino acids to the ribosomes to make proteins. Introns are spliced out of these molecules, which contain uracil. For 10 points, name this class of nucleic acids, the "messenger" variety of which is transcribed from DNA.
The first isolated aptamers were made of these molecules. These are the molecules that most frequently form stem loops or "hairpins."
