If a short sequence of DNA is 5' AATTGCCGT 3', what is its complementary sequence?
A
3' TTAAGCCGA 5'
B
3' CCGGTTGAA 5'
C
3' AATTGCCGT 5'
D
3' TTAACGGCA 5'
Verified step by step guidance1
Identify the base pairing rules for DNA: Adenine (A) pairs with Thymine (T), and Cytosine (C) pairs with Guanine (G).
Write down the original DNA sequence from 5' to 3': 5' AATTGCCGT 3'.
Determine the complementary bases for each nucleotide in the sequence by applying the base pairing rules.
Since the complementary strand runs in the opposite direction, write the complementary sequence from 3' to 5'.
Verify that the complementary sequence matches the correct answer by comparing each base pair.
