Solution

The correct option is C UAACCUAGA
RNA is synthesized by RNA polymerase enzyme using anticoding DNA strand as a template. The nitrogenous bases in DNA and RNA are adenine, guanine, cytosine, thymine and uracil. The purines adenine and guanine and the pyrimidines cytosine are common to both DNA and RNA. DNA has the pyrimidine thymine; RNA has the pyrimidine uracil. Adenine pairs with thymine/uracil and guanine with cytosine. Thus, the sequence in mRNA transcribed from a piece of DNA having a sequence ATTGGATCT will be UAACCUAGA; option E is correct. The presence of thymine in options A, C and D makes them incorrect. Complementary base pairing is not followed in option B. Correct answer is E.
