How are regular nucleotides and dideoxynucleotides different?

Regular nucleotides are fluorescently labeled, but dideoxy nucleotides are not.

Dideoxy nucleotides stop the elongation of the DNA strand during PCR.

Dideoxy nucleotides are for making RNA, but regular nucleotides are for making DNA.

MULTIPLE CHOICE QUESTION

Dideoxynucleoside triphosphates (ddNTPs) are used in sequencing DNA because:

ddNTPs are fluorescent.

ddNTPs are incorporated very efficiently into DNA by DNA polymerase.

ddNTPs cannot be incorporated into DNA by DNA polymerase.

ddNTPs prevent further DNA synthesis once they are incorporated into the DNA sequence.
