<h2>Answer:</h2>
The mRNA is important for carrying the sequence information of amino acid in poly peptide chain. While tRNA carry the specific amino acids from cytoplasm to the poly peptide chain according to the message in mRNA.
<h3>Explanation:</h3>
- mRNA is the message from the DNA in the form of specific nucleotide sequence.
- mRNA is complementary sequence of nucleotide formed in the process of transcription in nucleus.
- While tRNA are also produced in the nucleus from the DNA but they do not contain any message for the poly peptide production. While they are transported to cytoplasm and their function is the transport of amino acid from cytoplasm to growing poly peptide chain.
