Verified step by step guidance
1
Understand that DNA is composed of two strands that are complementary to each other, meaning each base on one strand pairs with a specific base on the opposite strand.
Recall the base pairing rules for DNA: Adenine (A) pairs with Thymine (T), and Cytosine (C) pairs with Guanine (G).
Identify the given DNA strand: 5'-ATCGGTA-3'.
Apply the base pairing rules to each nucleotide in the given strand: A pairs with T, T pairs with A, C pairs with G, G pairs with C, G pairs with C, T pairs with A, and A pairs with T.
Write the complementary DNA sequence using the base pairs identified in the previous step, ensuring the sequence is in the 3' to 5' direction: 3'-TAGCCAT-5'.
