Answer:
An mRNA molecule
Step-by-step explanation:
Transcription is a process by which the information stored in a specific fragment of DNA called 'gene' is used to produce a complementary RNA molecule, usually a messenger RNA (mRNA). Subsequently, this mRNA is used as template to produce a polypeptide chain (i.e., a sequentially ordered amino acid chain) through the process of translation. A stop codon, also known as termination codon, is a triplet of nucleotide bases within an mRNA that signals the end of the protein when it is synthesized in the ribosome. There are three stop codons (UAG, UAA, and UGA) that are capable of stopping protein synthesis.
