What occurs during the process of DNA replication?

• A. The cell divides into two daughter cells
• B. RNA is synthesized from DNA
• C. DNA strands untwist and complementary nucleotides pair up
• D. A protein is formed from a DNA template

Answer: (C)

During DNA replication, one of the crucial processes is the unwinding of the double helix structure of the DNA molecule. This unwinding allows the two strands of the DNA to separate. Each of these separated strands then serves as a template for the synthesis of a new complementary strand. The complementary base pairing occurs according to the specific pairing rules – adenine pairs with thymine, and cytosine pairs with guanine. This ensures that the new strands are exact copies of the original strands. This process is essential for cell division and the transmission of genetic information from one generation to the next. As a result, when the replication is complete, two identical DNA molecules are formed, each comprising one original strand and one newly synthesized strand, a process known as semi-conservative replication.
