In a famous experiment, Matthew Meselson and Franklin Stahl grew E. coli cells in a medium containing only the "heavy" isotope of nitrogen, 15 N. These cells were then transferred to a medium with the "light" isotope of nitrogen, ¹4N. The results of the experiment supported the hypothesis of semiconservative replication, which was proposed by Watson and Crick. Heavy DNA (¹5N DNA), hybrid DNA, and light DNA (¹4N DNA) can be separated by centrifugation. If cells containing 15N DNA are transferred to a medium with only ¹4N NH4Cl as a nitrogen source, what percent of daughter molecules are composed of hybrid DNA after 3 generations? daughter molecules: %

Describe the double-stranded structure of DNA, and explainhow the AT/GC rule underlies the ability of DNA to be replicatedsemiconservatively
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. Howcan you explain these structures?

In the Meselson–Stahl experiment thatestablished the semiconservative nature of DNA replication,the extraction method produced short fragments of DNA. Whatsort of results might have been obtained with longer piecesof DNA?
In the concluding statement of Watson and Crick's seminal paper introducing the atomic structureof DNA, they write,"It has not escaped our notice that the specific pairing we have postulatedmediately suggests a possible copying mecha the genetic material (Watson, JDCrick, 1953)" Some consider this one of the biggest understatements in modern biology, butWatson and Crick couldn't confirm the mechanism for copying DNA because of lack of hardevidence. The scientists were racing to publish ahead of their competitors, so they included thestatement to be able to introduce the model before proof was available. The base-pairing inherentto the structure of DNA certainly strongly suggested a mechanism for creating an identical copy ofthe DNA, but it wasn't proven until Meselson and Stahl (1958) carried out their classic study. Notonly was this a landmark experiment for the essential process it helped to define, but it was alsorecognized for its elegant simplicityFor these reasons. Meselson and…
Replication involves a period of time during which DNA is particularly susceptible to the introduction of mutations. If nucleotides can be incorporated into DNA at a rate of 20 nucleotides/second and the human genome contains 3 billion nucleotides, how long will replication take? How is this time reduced so that replication can take place in a few hours?

What result would Meselson and Stahl have obtained if the replication of DNA were conservative (i.e., the parental double helix stayed together)? Give the expected distribution of DNA molecules after 1.0 and 2.0 generations for conservative replication.
Wild-type E. coli takes up and concentrates a certain redfood dye, making the colonies blood red. Transposonmutagenesis was used, and the cells were plated on fooddye. Most colonies were red, but some colonies did nottake up dye and appeared white. In one white colony, theDNA surrounding the transposon insert was sequenced,with the use of a DNA replication primer identical withpart of the end of the transposon sequence, and the sequence adjacent to the transposon was found to correspond to a gene of unknown function called atoE, spanning positions 2.322 through 2.324 Mb on the map(numbered from an arbitrary position zero). Propose afunction for atoE. What biological process could be investigated in this way, and what other types of white colonies might be expected?
On further analysis of the DNA described in conceptual questionC21, you discover that the triplex DNA in this alien organism iscomposed of a double helix with a third strand wound within themajor groove (just like the DNA in Figure shown). How would youpropose that this DNA is able to replicate itself? In your answer,be specific about the base-pairing rules within the double helixand which part of the triplex DNA would be replicated first.
