If the base sequence in a portion of a strand of DNA is TTGGAGTACC, what is the base sequence in the strand of mRNA transcribed from this DNA?
A)TTGGAGTACC
B)AACCTCATGG
C)UUCCTCUTGG
D)AACCTCATUU
E)AACCUCAUGG

The base sequence in the mRNA strand is determined by the complementary base pairing with the DNA strand during transcription. The RNA strand will have the same nucleotides as the DNA strand except for thymine (T) being replaced with uracil (U). Therefore, the mRNA sequence transcribed from the given DNA sequence would be AACCUCAUGG.
