Which set correctly assigns functions to the three types of RNA?

  1. AmRNA carries amino acids; tRNA is a component of the ribosome; rRNA carries codons from DNA
  2. BmRNA is a component of the ribosome; tRNA carries codons; rRNA carries amino acids
  3. CmRNA stores genetic information permanently; tRNA copies DNA; rRNA transports amino acids
  4. DmRNA carries the codons copied from DNA; tRNA carries amino acids to the ribosome; rRNA is a structural component of the ribosome

Answer: D

mRNA is the template with codons, tRNA brings specific amino acids (its anticodon pairs with the codon) and rRNA with proteins makes up the ribosome.
