If a DNA Sequence Reads TTGCGATCG, What MRNA Will It

Question

If a DNA sequence reads TTGCGATCG, what mRNA will it encode?
A) TTGCGUTCG
B) AACGCTAGC
C) AACGCUAGC
D) TTGCGATCG
E) UUCGCTUGC

Accepted Answer

To determine the mRNA sequence of the given DNA sequence, we need to follow the transcription rule, where T (thymine) in DNA is replaced by U (uracil) in mRNA. Thus, the mRNA sequence of TTGCGATCG will be AACGCUAGC. Choice C matches this mRNA sequence, making it the correct answer.
