Question

fill in the complementary nucleotides from the original dna strand original dna atg caa tag complementary dna

Explanation:

Step1: Recall base - pairing rules

In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G).

Step2: Find complementary nucleotides for each base in the original strand

For the original DNA strand "ATG CAA TAG":

• For "A" in the first position of "ATG", the complementary base is "T".
• For "T" in the second position of "ATG", the complementary base is "A".
• For "G" in the third position of "ATG", the complementary base is "C".
• For "C" in the first position of "CAA", the complementary base is "G".
• For "A" in the second position of "CAA", the complementary base is "T".
• For "A" in the third position of "CAA", the complementary base is "T".
• For "T" in the first position of "TAG", the complementary base is "A".
• For "A" in the second position of "TAG", the complementary base is "T".
• For "G" in the third position of "TAG", the complementary base is "C".
