What is the building block of DNA?
Bogdan [553]
Deoxyribonucleoside Triphosphate, which is the more specific form of Deoxyribonucletides.

When DNA is synthesised by DNA polymerase by complimentary base pairing, 2 phosphate groups from Deoxyribonucleoside Triphosphate breaks away, releasing energy from the binding of the Deoxyribonucleotide to the adjacent Deoxyribonucleotide molecule via phosphodiester bond. These molecules will be called Deoxyribonucleoside Monophosphates.

Thus, the general name of the building block of DNA is Deoxyribonucleotide, and the more specific names depend on at which stage of DNA replication you are referring to.

Hope this helps! :)
