Introduce your students to the exciting science of DNA Sequencing. This kit contains the four Ready-to-Load sequenced DNAs (nucleotides A, C, G, & T) in an easy to use, safe format. Students load the four separate reactions into agarose gels, run the gels, stain them, and actually read the DNA sequence. This experiment can be used to introduce genome concepts and help your students gain a better understanding of the science behind DNA sequencing. Expt. 120.
