Answer:
An mRNA template is used to create an amino acid chain.
Step-by-step explanation:
During the transcription, one DNA is used as a template and mRNA is made complementary to it. In mRNA, uracil comes complementary to adenine, not thymine.
During the process of translation, this mRNA molecule is used as a template to create an amino acid chain. mRNA strand contains triplet codons and each triplet codons codes for an amino acids. So these amino acids joins and male polypeptide chain. Therefore amino acid chain is not formed during transcription.
