It is common to use ddntps (dideoxynucleoside triphosphates) for sequencing dna because, when incorporated into a growing dna polymer, the ddntp acts as a chain terminator, allowing the researcher an opportunity to determine the last-added base to a given chain. from your knowledge of nucleotide structure and dna synthesis, what is the most likely attribute of ddntps for dna sequencing?

a. the ddntps lack a 5′ carbon.

b. the ddntps lack a 3′ hydroxyl group.

c. the ddntps lack a nitrogenous base.

d. the ddntps lack the sugar component.
