Question

Write the complementary DNA base sequence for \(5^{\prime}\)-CCGTACGA-3'.

Short answer

Answer: The complementary DNA base sequence for the given DNA strand is \(5^{\prime}\)-GGCATGCT-3'$.

Step-by-step solution

Write down the given DNA sequence

The given DNA sequence is \(5^{\prime}\)-CCGTACGA-3'$.

Complementary base pairing

Now find the complementary base for each nucleotide in the given sequence according to the base pairing rules: - C pairs with G - C pairs with G - G pairs with C - T pairs with A - A pairs with T - C pairs with G - G pairs with C - A pairs with T

Write the complementary DNA sequence

Now write down the complementary DNA sequence using the base pairs found in step 2. The complementary DNA sequence is \(5^{\prime}\)-GGCATGCT-3'$.
