Chapter 15, Problem 6QP
Which of the following best describes the process of DNA sequencing?
- a. DNA is separated on a gel, and the different bands are labeled with fluorescent
nucleotides and scanned with a laser. - b. A laser is used to fluorescently label the nucleotides present within the DNA, the DNA is run on a gel, and then the DNA is broken into fragments.
- c. Nucleotides are scanned with a laser and incorporated into the DNA that has been separated on a gel, and then the DNA is amplified with PCR.
- d. Fragments of DNA are produced in a reaction that labels them with any of four different fluorescent dyes, and the fragments then are run on a gel and scanned with a laser.
- e. DNA is broken down into its constituent nucleotides, and the nucleotides are then run on a gel and purified with a laser.
