The modified nucleotides used in DNA sequencing have a(n) ____ instead of a hydroxyl group on the 3' carbon.
A)hydrogen
B)nitrogen
C)oxygen
D)amine group
E)phosphate group

Question

Quizplus · Accepted Answer

The modified nucleotides used in DNA sequencing have a hydrogen atom instead of a hydroxyl group on the 3' carbon. This modification is called dideoxy sequencing or Sanger sequencing, and it allows for the termination of DNA synthesis, resulting in DNA fragments of different lengths that can be used to determine the sequence of the original DNA template.
