A) 5'-AGCTCGATCGA-3'
B) 5'-AGCUCGAUCGA-3'
C) 5'-UCGAGCUAGCU-3'
D) 3'-UCGAGCUAGCU-5'
E) 3'-TCGAGCTAGCT-5'

To transcribe DNA to RNA, we replace each DNA base with its complementary RNA base. The complementary RNA base for cytosine (C) is guanine (G), the complementary RNA base for guanine (G) is cytosine (C), the complementary RNA base for adenine (A) is uracil (U), and the complementary RNA base for thymine (T) is adenine (A). Therefore, the transcribed RNA for the given DNA strand AGCTCGATCGA would be UCGAGCUAGCU, which matches choice B.
