3. The tRNA aids in translation by care the amino acid read on the mRNA and also carrying the complimentary anticodon to match the codon for the amino acid on the mRNA.
4. THE rRNA also known as the ribosomal RNA is what makes up the one of the main component of the ribosomes. A major part also helps in the period bond formation
