What type of rna acts like a delivery truck, delivers amino acids to the ribosome for protein synthesis, and then leaves empty again, to go collect another amino acid?

a. transfer rna

b. messenger rna

c. ribosomal rna

d. mitochondrial rna?

The correct answer is a. transfer rnaRNA (tRNA).

tRNA (transfer RNA) plays and important role in the formation of proteins using mRNA transcript. It brings specific amino acid to the ribosome site where mRNA is present. It has anticodon site (that is complementary to the specific three nucleotide sequence called codon which are present in the mRNA) and an amino acid binding site where amino acid is attached.

Thus, by reading specific codons of the mRNA, particular amino acids are assembled in a sequence (through peptide bond) and protein is synthesised.

Therefore, tRNA acts like a deliver truck that delivers particular amino acid.

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.
