If a scientist wanted to compare the expression of one gene under two sets of conditions, chain termination is the technique they would use.
Chain termination is any chemical response that ceases the formation of reactive intermediates in a sequence propagation step withinside the route of a polymerization, efficaciously bringing it to a halt.
Sanger sequencing, additionally referred to as the “chain termination technique”, is a way for figuring out the nucleotide collection of DNA. The approach become evolved with the aid of using time Nobel Laureate Frederick Sanger and his colleagues in 1977, subsequently the call the Sanger Sequence.
