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: -DNA sequencing refers to the general laboratory technique for determining the exact sequence of nucleotides, or bases, in a DNA molecule. The sequence of the bases (often referred to by the first letters of their chemical names: A, T, C, and G) encodes the biological information that cells use to develop and operate.
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.
