Chapter 17, Problem 32
How many daughter strands are formed during the replication of DNA?
Verified step by step guidance1
Understand that DNA replication is a biological process where a DNA molecule is copied to produce two identical DNA molecules. This process is essential for cell division.
Recall that DNA replication is semi-conservative, meaning each of the two original strands of the DNA molecule serves as a template for the formation of a new complementary strand.
During replication, the enzyme DNA polymerase synthesizes a new strand by matching complementary nucleotides (A pairs with T, and G pairs with C) to the template strand.
As a result of this process, two DNA molecules are formed, each consisting of one original (parent) strand and one newly synthesized (daughter) strand.
Therefore, during DNA replication, two daughter strands are formed, one for each of the original template strands.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
DNA Replication
DNA replication is the biological process through which a cell duplicates its DNA, resulting in two identical copies. This process is essential for cell division and occurs during the S phase of the cell cycle. It involves unwinding the double helix and synthesizing new strands complementary to each original strand.

Leading and Lagging Strands
During DNA replication, two types of daughter strands are formed: the leading strand and the lagging strand. The leading strand is synthesized continuously in the direction of the replication fork, while the lagging strand is synthesized in short segments, known as Okazaki fragments, in the opposite direction. This distinction is crucial for understanding how DNA is replicated efficiently.

Semi-Conservative Replication
DNA replication is described as semi-conservative because each new DNA molecule consists of one original (parental) strand and one newly synthesized (daughter) strand. This mechanism ensures genetic fidelity, as the original strands serve as templates for the formation of the new strands, reducing the likelihood of errors during replication.
