Question

the mrna transcript and the dna sequence are shown below
dna 3-agc cgt atc-5
mrna 5-tcg gca tag-3
another student found a mistake in the transcription.
using the drop-down menus. explain how to correct the transcription mistake.
nucleotides in the mrna transcript should be replaced with nucleotide

Explanation:

In transcription, mRNA nucleotides pair with DNA template strands using complementary base pairing: A pairs with U, T pairs with A, C pairs with G, and G pairs with C. The given DNA template is 3'-AGC CGT ATC-5'. For the third DNA triplet 3'-ATC-5', the correct complementary mRNA triplet should be 5'-UAG-3', but the provided mRNA has 5'-TAG-3'. The incorrect T in mRNA needs to be replaced with U.

Answer:

The T nucleotide in the mRNA transcript should be replaced with a U nucleotide.
