Tomato yellow leaf curl virus (TYLCV), a member of the genus Begomovirus, is responsible for one of the most devastating viral diseases in tomato-growing countries and is becoming a serious problem in many subtropical and tropical countries. The climate in Korea is getting warmer and developing subtropical features in response to global warming. These changes are being accompanied by TYLCV, whi...

We compared the accuracy of genotyping for DNA extracted from lymphocytes to that of DNA amplified from buccal epithelial cells. Amplification was via a rolling circle/phi29 DNA polymerase commercial kit. Paired buccal and lymphocyte DNA samples were available from 30 individuals. All samples were genotyped for 12 SNPs, 5 microsatellites and 2 VNTRs. The accuracy of genotyping (no-call proporti...

Forensic biological evidence often contains low quantities of DNA or substantially degraded DNA which makes samples refractory to genotype analysis. One approach that shows promise to overcome the limited quantity of DNA is whole genome amplification (WGA). One WGA technique, termed rolling circle amplification (RCA), involves the amplification of circular DNA fragments and this study evaluates...

MicroRNAs (miRNAs) are a class of RNAs that play important regulatory roles in the cell. The detection of microRNA has attracted significant interest recently, as abnormal miRNA expression has been linked to cancer and other diseases. Here, we present a straightforward method for isothermal amplified detection of miRNA that involves two separate nucleic acid-templated chemistry steps. The miRNA...

Single-walled carbon nanotubes can be readily wrapped in and dispersed by long single-stranded DNA molecules (ssDNAs) synthesized by rolling circle amplification.
