Reaction time biology practical
WebPolymerase chain reaction, or PCR, is a technique to make many copies of a specific DNA region in vitro (in a test tube rather than an organism). PCR relies on a thermostable DNA polymerase, Taq polymerase, and requires DNA primers designed specifically for the DNA region of interest. In PCR, the reaction is repeatedly cycled through a series ... WebThe lowest reaction time equates to the person with the fastest reaction time – in this example, student A has the fastest reaction time (255 ms) and student C the slowest (267 ms) Exam Tip You could be asked to express answers in standard form or as ratios in an exam for this type of question.
