Detailed explanation-1: -Answer and Explanation: The correct answer is option c because the newly synthesized strand during DNA replication is complementary to the template strand and identical to the coding strand, the other strand of the original DNA.
Detailed explanation-2: -The four types of nitrogen bases found in nucleotides are: adenine (A), thymine (T), guanine (G) and cytosine (C). The order, or sequence, of these bases determines what biological instructions are contained in a strand of DNA.
Detailed explanation-3: -A nucleotide containing adenine base will bind with the nucleotide containing thymine, while a nucleotide containing guanine will bind with the nucleotide that has cytosine. Therefore, the sequence of the base pair in the newly synthesized strand would be AGCAT.
Detailed explanation-4: -During DNA replication, both strands of the double helix act as templates for the formation of new DNA molecules. Copying occurs at a localized region called the replication fork, which is a Y shaped structure where new DNA strands are synthesized by a multi-enzyme complex.
