One assumption made in bacterial production estimates from [3H]thymidine incorporation is that all heterotrophic bacteria can incorporate exogenous thymidine into DNA. Heterotrophic marine bacterium isolates from Tampa Bay, Fla., Chesapeake Bay, Md., and a coral surface microlayer were examined for thymidine uptake (transport), thymidine incorporation, the presence of thymidine kinase genes, an...

Theoretical methods, such as molecular mechanics and dynamics, are very useful in understanding differences interactions at the single molecule level. In life sciences, small conformational changes, including substituent modifications, often have a significant impact on function vivo. Changes binding between nucleic acid molecules proteins prime example. this study, we propose strategy to predi...
