Molecular gears: a pair of DNA circles continuously rolls against each other.
نویسندگان
چکیده
A pair of DNA nanocircles has been constructed to model gears. The nanogears can move against each other continuously. Each gear consists of a DNA duplex circle and three single-stranded teeth. The teeth on the two gears are brought together by linker strands, which are complementary to the gear teeth. The teeth are separated from each other by removal of the linker strands with a strand displacement mechanism.

A Comparative Study of Tooth Wear, Mechanical Power Losses and Efficiency in Normal and High Contact Ratio Asymmetric Spur Gears
The surface tooth wear which occurs at the gear contact region due to inadequate contact strength of the tooth is one of the predominant modes of gear failures. Currently, higher contact ratio spur gears are increasingly used in power transmission applications such as aircraft, wind turbine, automobiles and compact tracked vehicles due to their high load carrying capacity. In this work, the di...
متن کاملMolecular differentiation of sheep and cattle isolates of Fasciola hepatica using RAPD-PCR
Understanding genetic structure and status of genetic variation of Fasciola hepatica isolates from different hosts, has important implications on epidemiology and effective control of fasciolosis. Random amplified polymorphic DNA (RAPD-PCR) was used to study the genetic variation of F. hepatica in sheep and cattle. DNA was extracted from adult helminthes removed from livers of each infected ani...
متن کاملMolecular Detection of Chicken Anemia Virus from Native Larry-breed Chickens in Chaharmahal-va-Bakhtiyari Province, Iran
Background and Aims: Finding prevalence of chicken anemia virus (CAV) infection in native chickens is necessary to avoid transmission of infection to commercial flocks. In this paper we attempt to describe molecular detection of chicken anemia virus in native Larry-breed chickens in Chaharmahal-va-Bakhtiyari province in Iran for the first time. Materials and Methods: Blood samples were collect...
متن کاملStrategies and Clinical Applications of Next Generation Sequencing
Abstract DNA sequencing is one of the great valuable techniques in molecular biology, which can be used to detect the sequence of nucleotides in a DNA fragment. The high-throughput sequencing known as Next Generation Sequencing (NGS) revolutionized genomic research and molecular biology; therefore, the whole human genome can be sequenced with a low cost in several days. NGS technology is simi...
