Which of the following best describes Sanger sequencing?
A. By using dideoxynucleotides that don't
have a triphosphate group, there is no energy
to add it to the growing nucleotide strand and
hence it stops replication.
B. By using dideoxynucleotides, it stops the
addition of another nucleotide after it. This
can then be run on a regular gel to determine
the sequence.
C. By using dideoxynucleotides, it stops the
addition of another nucleotide. These are
known as chain terminators and have been
labeled with a specific probe to allow for
detection and hence the sequence.
D. By using dideoxynucleotides, you can tell
where they have been incorporated by using
microarray analysis.
E. By using dideoxynucleotides, you can tell
where they have been incorporated by the
difference in weight.
