        DNA Sequencing

        In this interactive activity adapted from the Dolan DNA Learning Center, examine the techniques geneticists use to read a sequence of DNA fragments. Sequencing enables scientists to analyze DNA and ultimately piece together the genomes of living organisms. The activity features Fred Sanger's original sequencing method, developed in 1977, and an automated version of Sanger's method that uses computers to read and interpret data. This newer technique provides a faster and more reliable means of sequencing.

        This media asset was adapted from Early DNA Sequencing and Cycle Sequencing.
