State the dual role of deoxyribonucleoside triphosphates during DNA replication.

Explanation

**Step-by-Step Solution:**

1. **Understanding Deoxyribonucleoside Triphosphates (dNTPs)**: Deoxyribonucleoside triphosphates are the building blocks of DNA. Each dNTP consists of a deoxyribose sugar, a nitrogenous base (adenine, thymine, cytosine, or guanine), and three phosphate groups.

2. **Role as Building Blocks**: The first major role of dNTPs during DNA replication is that they serve as the building blocks for the new DNA strand. When DNA is replicated, dNTPs are added to the growing DNA strand. The nucleotides are linked together through phosphodiester bonds, which form between the phosphate group of one nucleotide and the hydroxyl group of the sugar of another nucleotide. This process leads to the elongation of the DNA strand.

3. **Role as Energy Providers**: The second role of dNTPs is to provide energy for the DNA replication process. The high-energy bonds between the phosphate groups of dNTPs are broken during the addition of the nucleotide to the growing DNA strand. This release of energy is essential for driving the polymerization reaction, allowing the DNA polymerase enzyme to catalyze the formation of the new DNA strand.
