What strand of mRNA would be transcribed from the following strand of DNA: AATG? What strand of mRNA would be transcribed from the following strand of DNA: AATG? GGUA UUAC TTAC TTUC UUGT

UUAC

Explanation:

Transcription is the first process of gene expression in organisms. It involves synthesizing a complementary strand of mRNA from a DNA template. This process is carried out by an enzyme called RNA polymerase, which first unwinds the DNA molecule and then adds complementary nucleotide bases to the growing RNA molecule.

Adding of nucleotides by RNA polymerase follows the complementary base pairing rule, which is a phenomenon whereby Adenine (A) binds to Thymine (T) in an hydrogen bond and Cytosine (C) binds to Guanine (G), A-T, G-C. During transcription, Uracil (U) replaces Thymine.

RNA polymerase synthesizes a nucleotide base complementary to the one it reads on the DNA i. e if it reads Adenine on the DNA, it adds Uracil.

Hence, a DNA molecule with nucleotide AATG will be read by RNA polymerase and it becomes transcribed into a RNA molecule with nucleotide UUAC.
