Question

Consider the following DNA nucleotides, where A, C, G, and T represent adenine, cytosine, guanine, and thymine:
TAC TTT TTG CTC ATC
Which of the following is the transcribed sequence in mRNA ?

• A. TUC TTT TTG CTC ATC
• B. CGT CCC CCA TCT GCT
• C. ATG AAA AAC GAG TAG
• D. AUG AAA AAC GAG UAG
• E. CGU CCC CCA UCU GCU

Answer 1

The correct option is D AUG AAA AAC GAG UAG

• The mRNA sequence is complementary to that of the DNA template strand.
• RNA differs from DNA in having Uracil base in place of Thymine; A pairs with U and G with C in RNA.
• The given DNA sequence " TAC TTT TTG CTC ATC" will code for AUG AAA AAC GAG UAG.
  Thus, the correct answer is option D.
