A) 5-GACUCGAAC-3
B) S-CAAGCUCAG-S
C) 5-GUUCGAGUC-3
D) S-CUGAGCUUG-S
Correct Answer: C
Solution :
DNA is made up of two polynucleotide chains having antiparallel polarity. Therefore, when one chain has\[5\to 3\]polarity the other chain will have \[3\to 5\] polarity. Thus, if the sequence of the bases in the coding strand of a double - stranded DNA is \[5-GTTCGAGTC-3,\] its complementary strand will have \[3-CAAGCTCAG-5.\] But in the case of bases in the transcript {i.e., when mRNA is formed). The sequence will be 5-GUUCGUGUC-3, i.e., exactly similar to the coding strand excepting at the place of thymine (T) which will be replaced by uracil (U).
