Multiple-choice questions may continue on the next column or page find all choices before answering. 001 2.0 points Chelex beads in the TE incubation solution are used to enhance genomic DNA isolation. If the chelex beads are carried over into the PCR mix, the subsequent PCR reaction 1. would not be affected because the beads are inactivated at 95 C. 2. would be helped because the beads chelate inhibitors of Taq Polymerase. 3. would be inhibited because the beads chelate the enzyme Taq Polymerase. 4. would be inhibited because the beads chelate divalent cations. 5. would not be affected because the beads are only added to help lyse the cells. 002 2.0 points pYou have cloned and sequenced the ITS re- gion from the 18S rRNA genes of 11 genera (A-K). You made a phylogenetic cladogram from these sequences. Answer the follow- ing true/false questions based on this anal- ysis:/p pI. (T/F) There are three majorysis:/p pI....
