You need to discuss the different roles of different types of RNA:
mRNA allows the creation of a primary transcript of DNA which can be taken from the nucleus to the ribosome.
rRNA makes up the structure of the ribosome, where translation, the synthesis of a polypeptide chain, occurs.
tRNA transports amino acids to the ribosome and matches the RNA codon with its anticodon, and joins the amino acid to the polypeptide chain that is being created.
