Question

what are the types of rna?
messenger rna (aka mrna) carries the message for polypeptide assembly in the form of a series of three - letter “words” called
transer rna (aka trna) has an which allows it to deliver the correct to the ribosome to assemble polypeptides
ribosomal rna (aka rrna) makes up the ribosome which reads and displays the message of mrna and creates the peptide bonds between amino acids to create a (primary structure of a protein).

Explanation:

Messenger RNA (mRNA) carries genetic information in the form of codons (three - letter "words"). Transfer RNA (tRNA) has an anticodon which pairs with the codon on mRNA and delivers the correct amino acid to the ribosome. Ribosomal RNA (rRNA) is a component of the ribosome, which reads mRNA and forms peptide bonds between amino acids to create a polypeptide chain (the primary structure of a protein).

Answer:

Messenger RNA (mRNA): codons
Transfer RNA (tRNA): anticodon, amino acid
Ribosomal RNA (rRNA): ribosome, polypeptide chain
