Biochemistry : HBondingDNA (9 Variations)
The structure and replication of DNA are strongly dependent on the hydrogen bonding system present in the double helix. How many functional groups in thymine can participate in hydrogen bonding? (This means all the groups, not just the ones that actually participate in hydrogen bonding in the double helix.)

Nucleic Acids / DNA / RNA
Biochemistry : Replication (8 Variations)
Which of the following is NOT a feature of replication?
Nucleic Acids / DNA / RNA
Biochemistry : ComplementaryDNA (20 Variations)
Determine the sequence of the complementary DNA strand for the following sequence. (Note: Complementary strands match up 5' ends to 3' ends.)

A-DNA and B-DNA: Comparing Their Historical X-ray Fiber Diffraction Images  Amand A. Lucas
This paper provides a comparative explanation of the structural content of the diffraction diagrams of A-DNA and B-DNA that facilitated the discovery of the double-helical structure of DNA by Watson and Crick in 1953. This analysis is supported a method that simulates both A-DNA and B-DNA X-ray images optically.

DNA Profiling of the D1S80 Locus: A Forensic Analysis for the Undergraduate Biochemistry Laboratory  D. Dewaine Jackson, Chad S. Abbey, and Dylan Nugent
Describes a laboratory exercise in DNA profiling that can be used to demonstrate four fundamental procedures: isolation of genomic DNA from human cells, use of the polymerase chain reaction to amplify DNA, separation of amplified DNAs on agarose and polyacrylamide gels, and quantitative analysis of data (while comparing two different gel separation techniques).

Testing for Ultraviolet Toxicity Using Fungi  Marcelo Vital and Patricia Esperón
In this article, we describe a laboratory project quantifying the effects of UV radiation on a suspension of living cells. This laboratory experiment was designed for undergraduate students in biochemistry. The experiment was carried out employing different fungi strains, changing the dosage of radiation, the distance to the UV source, and the exposure period to the UV radiation. The quantity of viable spores was calculated and the doseresponse curves were drawn. Students were able to prove that 100% of mortality was achieved with the longest time of exposure.

Molecular Models of DNA  William F. Coleman
The featured molecules this month come from the paper by David T. Crouse on the X-ray determination of the structure of DNA. Given that most students are aware of the double helix, it seems appropriate to back up a little and examine the components that give rise to this structure. Accordingly, the molecule collection includes: Purine and pyrimidine, structural precursors of the four bases found in DNA: cytosine (C), thymine (T), adenine (A), and guanine (G) The four corresponding deoxyribonucleosides The four deoxyribonucleotides (the nucleoside monophosphates) A two-base-pair fragment showing the AT and GC hydrogen-bonded complements Several small 24-base-pair DNA fragments polyAT, polyGC, and a random array of bases. The DNA fragments provide a good opportunity to have students explore features of the Jmol and Chime menus. Using the Jmol menu as an example (right-click on the structure to bring up the menu) students can use the measuring tools to get an idea of the length of a complete turn in the DNA, the relative widths of the major and minor grooves, and the diameter of the helix. They can use the coloring schemes to detect the various base pair combinations, and learn to read the code for the random sequence. In Chime they can use the Shapely coloring scheme for this same purpose. Exploring other aspects of the menu will allow students to present the molecules in the various forms, including ribbon and cartoon views. In RNA, thymine is replaced by uracil, and the sugar moiety has an axial hydroxyl group on the carbon atom adjacent to the base binding site (the 2? carbon). The structures of uracil and of uridine monophosphate are included in the molecule collection. Students can use the Web to download and examine more complex DNAs using a site such as the Nucleic Acid Database at Rutgers University.
