Inter-DNA Attraction Mediated by Divalent Counterions

open access: yes, 2007
Can nonspecifically bound divalent counterions induce attraction between DNA strands? Here, we present experimental evidence demonstrating attraction between short DNA strands mediated by Mg2 ions.

Optimization of DNA Extraction Methods in Fresh Meat (Rat and Chicken Meat) based on Incubation Time

open access: yesIndonesian Journal of Halal Research, 2023
DNA (deoxyribonucleic acid) extraction method is the process of separating DNA from the sample. In this process, the DNA obtained must be protected from contamination by RNA, carbohydrates, lipids, and proteins.
