Verified step by step guidance

Understand the concept of DNA replication: DNA replication is the process by which a DNA molecule makes a copy of itself. It is essential for cell division and is a key part of the cell cycle.

Learn about the semi-conservative model: In the semi-conservative model of DNA replication, each of the two strands of the original DNA molecule serves as a template for the production of the complementary strand. This results in two DNA molecules, each consisting of one original strand and one newly synthesized strand.

Compare with other models: The conservative model suggests that the entire original DNA molecule is conserved in one of the two daughter molecules, while the other is completely new. The dispersive model suggests that each strand of both daughter molecules contains a mixture of old and new DNA.

Identify the correct description: Based on the semi-conservative model, the correct description is that each new DNA molecule consists of one original strand and one newly synthesized strand.

Review the options: Evaluate each option given in the problem and match it with the semi-conservative model to identify the correct answer.
