74. Which of the following is the best second-generation sequencing method to examine the whole human genome?

A. Ion semiconductor sequencing

B. Sanger Sequencing

C. Pyrosequencing

D. Sequencing by synthesis

Homework Answers

Answer #1

Answere : The correct option is option (A) i.e. Ion semiconductor sequencing.

Explanation : Ion semiconductor sequencing  (Ion Torrent Sequencing) is the best second-generation sequencing method to examine the whole human genome.

This method of DNA sequencing is based on the hydrogen ions detection. Hydrogen ions are released during DNA polymerization. It utilizes release of hydrogen ions during sequencing reaction to detect sequencing of a cluster.
