Given the DNA sequence 5'-ATCGGTA-3', which is the correct complementary DNA strand?
A
3'-TAGCCAT-5'
B
3'-TACCGAT-5'
C
3'-UAGCCAU-5'
D
3'-ATCGGTA-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 strand: 5'-ATCGGTA-3'.
Determine the complementary bases for each nucleotide in the original strand using the base pairing rules.
Remember that the complementary strand runs in the opposite direction (3' to 5'), so reverse the order of the complementary bases accordingly.
Combine the complementary bases in the 3' to 5' direction to write the full complementary strand.
