Here's a breakdown:

* Deoxyribonucleoside: This refers to the building blocks of DNA, which are composed of a deoxyribose sugar and a nitrogenous base (adenine, guanine, cytosine, or thymine).

* Triphosphate: This indicates that the deoxyribonucleoside has three phosphate groups attached to it.

During DNA replication, DNA polymerases use the energy released from breaking the bond between the second and third phosphate groups of a dNTP to add the corresponding nucleotide to the growing DNA strand.
