Which of the following is the complimentary sequence of 5' TTAAGCTAC 3'?
High-Yield Explanation
The complementary sequence of 5' TTAAGCTAC 3' is 3'AATTCGCATG 5'or 5' GTACGCTTAA 3'. Complementary sequence of 5'-3' end always proceeds from 3'- 5. In the double stranded DNA, the bases of one strand of DNA pairs with the bases of the second strand in such a way that Adenine (A) always pairs with Thiamine (T) and Cytosine (C) always pairs with Guanine (G).
