If the base sequence in a portion of a strand of DNA is ACTAAGATC, what is the base sequence in the strand of mRNA transcribed from this DNA?
A)ACTAAGATC
B)TUATTCTAU
C)UGAUUCUAG
D)TGUTTCTUG
E)TGATTCTAG

During transcription, DNA is used as a template to make mRNA. The base pairs in DNA (A, C, T, and G) pair with complementary nucleotides in mRNA (U, G, A, and C). The DNA sequence ACTAAGATC would pair with the mRNA sequence UGAUUCUAG, using the complementary base pairs A-U, C-G, T-A, and G-C. Therefore, the correct answer is C) UGAUUCUAG.
