Between consecutive occurrences of the sequence 5'-TACGGC-3'?A single strand of DNA, 24 nucleotides long, with the sequence 5'-TTTCCCgggAAAgggTTTAAAggg-3' is in a test tube. (Note that G's are shown in lowercase, so that your eye can better distinguish them from C's) Other than the appropriate buffer solution, what else needs to go in the test tube to so that we end up with a piece of double stranded DNA, 24 base pairs long, with the above sequence comprising one of the two strands?

- When a double-stranded DNA molecule is exposed tohigh temperature, the two strands separate, and themolecule loses its helical form. We say the DNA hasbeen denatured. (Denaturation also occurs whenDNA is exposed to acid or alkaline solutions.)a. Regions of the DNA that contain many A–T basepairs are the first to become denatured as the temperature of a DNA solution is raised. Thinkingabout the chemical structure of the DNA molecule, why do you think the A–T-rich regionsdenature first?b. If the temperature is lowered, the original DNAstrands can reanneal, or renature. In addition to thefull double-stranded molecules, some molecules ofthe type shown here are seen when the moleculesare examined under the electron microscope.

How do you thinkthat scientists prepare gels of different average poresizes? (Hint: Agarose gels are made in a mannersimilar to gelatin desserts such as JELL-O.)
