Fluorescent Sanger dideoxy sequencing methods uses what meth

Fluorescent Sanger dideoxy sequencing methods uses what method to discriminate between the 4 different nucleotides? Centrifugation sedimentation gradient. Fluorescently labeled dNTPs Fluoresently labeled dATP. Different fluorochromes attached to the four different ddNTPs.

Solution

d)different fluorochrome attached to the different ddNTPs because each one of them -(dATP, dGTP, dCTP, and dTTP) has a different fluorochrome attached to it which ensures different fluorochromes.
