Question

What strand of mRNA would be transcribed from the following strand of DNA: AATG?

A) TTUC
B) TTAC
C) UUGT
D) UUAC
E) GGUA

Answer 1

The mRNA strand transcribed from the DNA sequence AATG is UUAC, with each DNA base pairing with its complementary mRNA base.

Step-by-step explanation:

The strand of mRNA that would be transcribed from the DNA strand AATG would be complementary to the given DNA sequence. This means that each DNA nucleotide is paired with its complementary RNA nucleotide: adenine (A) with uracil (U), thymine (T) with adenine (A), cytosine (C) with guanine (G), and guanine (G) with cytosine (C). Therefore, the strand of mRNA transcribed from the DNA strand AATG would be UUAC.
