Explanation:
The difference among mRNA, tRNA and rRNA are:
mRNA: It carries DNA's protein building information from nucleus to the cytoplasm. It is also read as codons nucleotide triplet that indicate specific amino acids .
rRNA: The function of rRNA is to join amino acids to the peptide bonds.
tRNA: Delivers amino acids to the site of protein synthesis. It also has an anticodon that interact with specific codon of another nucleus.
The similarity among mRNA, rRNA and tRNA is that they all consists of ribonucleic acid and can exist outside the nucleus in eukaryotes.
