Which of the following is true of the Sanger sequencing method?
A. It requires an RNA template to copy.
B. It incorporates dNTPs using an RNA polymerase.
C. It requires a primer for the polymerase; the primer is radiolabelled so the sequences generated can be visualized.
D. It requires chain terminating ddNTPs which lack a 2'OH and are thus unable to form a bond with the next nucleotide.
E. The sequencing reaction products are separated by affinity chromatography.

Answer the following statements true (T) or false (F)
1. Scientists developing drought tolerant plants can use the knowledge of relative water content as models for predicting how these plants will respond to stress. 2. If scientists want to develop plants that can withstand cold conditions they would breed for the ability of the plant to increase solutes in cells. 3. One possible explanation for the reason water can be transported up the vessels in plants is because of adhesion of water to the lignified walls. 4. Given the same driving force, water transport in vessels is more rapid than that in tracheids because of the end wall perforation of vessels. 5. Liquids move faster in plant cells by bulk flow than by diffusion.
