Why does the cell need both mRNA and tRNA in order to synthesize a protein like hemoglobin?

mRNA is the messenger RNA that carries the instructions on how to synthesize the proteins and tRNA is the transfer RNA that actually moves the instructions into doing what they're supposed to.

The mRNA is required to carry the genetic information from the DNA to protein, while the tRNAs are responsible for transporting the correct amino acids to the growing polypeptide during translation.

During gene transcription (in this case, the transcription of the hemoglobin gene), a fragment of DNA called gene is used as a template to create an mRNA.

Subsequently, this mRNA then carries the information encrypted in the linear order of nucleotides to the ribosomes in order to synthesize a protein during translation.

During translation, each tRNA transport a specific amino acid, which is added to the growing polypeptide chain.

In conclusion, the mRNA is required to carry the genetic information from the DNA to protein, while the tRNAs are responsible for transporting the correct amino acids to the growing polypeptide during translation.
