State the dual role of deoxyribonucleoside triphosphates during DNA replication.

Explanation

**Step-by-Step Solution:**

1. **Understanding DNA Replication**: DNA replication is the biological process through which a cell makes an identical copy of its DNA. This is essential for cell division and the propagation of genetic information.

2. **Role of Deoxyribonucleoside Triphosphates (dNTPs)**: During DNA replication, deoxyribonucleoside triphosphates (dNTPs) are the building blocks that are incorporated into the growing DNA strand. Each dNTP consists of a deoxyribose sugar, a nitrogenous base (adenine, thymine, cytosine, or guanine), and three phosphate groups.

3. **First Role - Building Block**: The primary role of dNTPs is to serve as the building blocks for the new DNA strand. When DNA polymerase synthesizes a new strand, it adds dNTPs complementary to the template strand, thus forming the new DNA molecule.
