C) free purine bases
D) free pyrimidine bases

Question

Quizplus · Accepted Answer

Primers used for DNA replication are synthesized from ribonucleoside triphosphates (rNTPs). These rNTPs are incorporated into RNA primers by the enzyme primase, which adds short RNA sequences complementary to the DNA template strand. The newly synthesized RNA primer provides a starting point for DNA polymerase to add deoxyribonucleotides and extend the DNA strand.
