Modeling Inhomogeneous DNA Replication Kinetics
In eukaryotic organisms, DNA replication is initiated at a series of chromosomal locations called origins, where replication forks are assembled proceeding bidirectionally to replicate the genome. The distribution and firing rate of these origins, in conjunction with the velocity at which forks progress, dictate the program of the replication process. Previous attempts at modeling DNA replicati...
متن کاملSequence-specific modification of genomic DNA by small DNA fragments.
Small DNA fragments have been used to modify endogenous genomic DNA in both human and mouse cells. This strategy for sequence-specific modification or genomic editing, known as small-fragment homologous replacement (SFHR), has yet to be characterized in terms of its underlying mechanisms. Genotypic and phenotypic analyses following SFHR have shown specific modification of disease-causing geneti...
متن کاملNumerical modeling of inhomogeneous DNA replication kinetics
We present a calculation technique for modeling inhomogeneous DNA replication kinetics, where replication factors such as initiation rates or fork speeds can change with both position and time. We can use our model to simulate data sets obtained by molecular combing, a widely used experimental technique for probing replication. We can also infer information about the replication program by fitt...
متن کاملRecovery of Small DNA Fragments from Serum Using Compaction Precipitation
BACKGROUND While most nucleic acids are intracellular, trace amounts of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), including micro RNAs, can also be found in peripheral blood. Many studies have suggested the potential utility of these circulating nucleic acids in prenatal diagnosis, early cancer detection, and the diagnosis of infectious diseases. However, DNA circulating in blood ...
متن کاملDirect PCR of small genomic DNA fragments from serum.
A simple and rapid method is described where human genomic DNA suitable for PCR was prepared from serum by microwave irradiation. We were able to reproducibly amplify single-copy gene sequences up to 442 bp from small quantities of serum without the need for DNA extraction. Genotyping results obtained from serum samples were shown to be identical to those derived from purified DNA from the same...
