The researchers found that the nucleic acid base pairs making up the steps of DNA's spiral staircase are continuously shape-shifting.
Another technology uses PCR to amplify microbial nucleic acid and ESI-MS to determine the nucleic acid base composition of the pathogen(s), and then compares this composition to a database for microbial identification.
A sampling of topics covered: vibrational dynamics of the double hydrogen bonds in nucleic acid base pairs, insight from singlet into triplet excited-state hydrogen bonding dynamics in solution, role of hydrogen bonds in photosynthetic water splitting, and theoretical studies of green and red fluorescent proteins.
Telomeres are made of the same nucleic acid bases as the rest of human genetic information but their job is a protective one.
In the literature there are several studies demonstrating the adsorption of nucleic acid bases on minerals.
In view of the above results on the interaction of prion protein with nucleic acids, we have undertaken a quantitative study of the prion protein interaction with synthetic DNAs by monitoring the fluorescent properties of dye intercalated in nucleic acid bases. We have used human recombinant prion protein, [alpha]-PrP, and nucleic acids having only GC sequence (gcDNA), only AT sequence (atDNA), and a model DNA (mDNA) containing equimolar ratio of AT and GC base pairs.
His research group was the first to produce a whole genome sequence (over 5,000 nucleic acid bases from the virus phiX174) and the first to sequence human genetic material (over 16,500 bases from human mitochondria--the tiny power stations that energise living cells).
Other topics include the atomic response of silicon clusters to an external electric field, lesions in nucleic acid bases, modeling dunes with vegetation and dunes on Mars, and cellular automata as a basic method for studying network dynamics.
Tidwell at University of North Carolina, discovered that certain unfused aromatic cationic molecules can specifically recognize and bind to not only narrow, DNA minor groove pockets rich in adenosine-thymine (or "AT") nucleic acid sequences, but also to wider minor groove pockets formed by sequences rich in guanosine-cytosine (or "GC") nucleic acid bases. The latter binding requires the drug molecules to stack on top of one another as a "stacked dimer" to fit into the wider spaces defined by these base pairs.
A number of workers have studied abiogenesis of various compounds of biological interest, such as amino acids, nucleic acid bases, sugars, and phospholipid-like materials in a laboratory simulated atmosphere.
