What is the correct statement with respect to ddNTPs?

A. They are dideoxynucleotide triphosphates

B. They are used in the termination of DNA sequencing

C. They are used for initiating DNA sequencing

D. They are used in the case if the starting amounts are large

Explanation: ddNTPs are dideoxynucleoside triphosphates. It is used in the case for termination of sequencing. It is so because, both the hydroxyl molecules are removed sequencing would be terminated. It is beneficial in the case if the initial amounts are less.
