Translate the mRNA codons into the amino acid sequence.

(DO put a comma and a space between the codons and make sure you spell out the names of amino acids!)

mRNA sequence: AUG; GCU; AAU; UGU; UGA

protein sequence: Met-Ala-Asn-Cys-stop codon (Methionine-Alanine-Asparagine-Cysteine-stop codon)

Explanation:

Transcription is the process by which a fragment of DNA (e.g., a gene) is used as template to synthesize a complementary RNA sequence, usually a messenger RNA (mRNA) sequence that is then used to synthesize a protein by the process of translation. In RNA, Adenine bases are replaced by Uracil bases. During translation, each codon (i.e., each triplet of nucleotides of the mRNA) indicates a specific amino acid (according to the genetic code).  UGA, UAA, and UAG are stop codons that signal the end or termination of translation.

tunica muscularis

Gastrointestinal motility results from coordinated contractions of the tunica muscularis, the muscular layers of the alimentary canal. Throughout most of the gastrointestinal tract, smooth muscles are organized into two layers of circularly or longitudinally oriented muscle bundles.
