Guida verificata passo dopo passo1
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 given: 5'-ATCGGTA-3'.
Determine the complementary bases for each nucleotide in the original strand using the base pairing rules.
Since the complementary strand runs antiparallel, reverse the direction to 3' to 5' when writing the complementary sequence.
Combine the complementary bases in the 3' to 5' direction to get the full complementary DNA strand.
