Final answer:
The complementary strand of the given DNA sequence AAATGCCGCC is TTTACGGCGG.
Step-by-step explanation:
The complementary strand of the DNA sequence AAATGCCGCC is TTTACGGCGG.The complementary DNA strand to the given DNA sequence AAATGCCGCC adheres to base-pairing rules where adenine (A) pairs with thymine (T) and cytosine (C) pairs with guanine (G). Applying these rules:
A pairs with T,
T pairs with A,
G pairs with C,
C pairs with G.
Therefore, the complementary strand is: TTTACGGCGG which corresponds to option A.
The rule for DNA base pairing is A-T and G-C. To find the complementary strand, we have to pair each base with its complementary base. For example, A in the original strand pairs with T in the complementary strand, and G pairs with C. So, the complementary strand of AAATGCCGCC would be TTTACGGCGG.
