Time Required: 20 or 30 min. DNA sequencing is a procedure for determining the primary structure of DNA, which is essential for understanding the function of genes. This kit provides a dry lab that explains DNA sequencing and analysis. Actual autoradiograms from a DNA sequencing experiment are provided for identification of mutated nucleotides. Note: This kit does not contain radioactive materials. For individual viewing of the autoradiograms, a light box such as the BT 552 Visualization System is required. CONTENTS: 5 Autoradiograms; Complete instructions, background information, and study questions.
