What actions would cause you step in and advise your lab partner that they are not following the proper operating procedures when using this instruments? Your partner draws liquid into the micropipette going to the second stop Your lab partner is holding the micropipettor horizontally once they have drawn up liquid Your lab partner is about to use the P200 to pipette 250uL of liquid Your lab partner dispenses liquid by pressing plunger to the first stop Your lab partner is using a P200 to transfer 25uL of liquid Your lab partner ejects tips into the designated "used tip" container All of the following are examples of materials that are bound by your purifying medium during the DNA extraction process, except: O Magnesium (Mg2+) O lipid membranes O endoplasmic reticulum O Calcium (Ca2+) Iron (Fe2+) O extraneous DNA What purpose does boiling your sample of cells for DNA extraction fulfill? O Reducing the amount of liquid in your sample O Allowing primers to be more mobile in finding proper sites to anneal to Reaching temperature for DNA denaturation O Lysing the cells in your sample O More than one of the above None of the above For the forward / right primer listed above, what is the first nitrogenous base added by DNA polymerase that extends from this primer?
