Nanopore Sequencing of the phi X 174 genome
Nanopore sequencing of DNA is a single-molecule technique that may achieve long reads, low cost, and high speed with minimal sample preparation and instrumentation. Here, we build on recent progress with respect to nanopore resolution and DNA control to interpret the procession of ion current levels observed during the translocation of DNA through the pore MspA. As approximately four nucleotide...
متن کاملGene D of bacteriophage phi X 174: absence of transcriptional and translational regulatory properties.
The only evidence that a gene product of phi chi 174 is involved in the regulation of phage transcription was presented by Clements and Sinsheimer (1974) for gene D. I. found, in attempting to investigate this possibility further, that the D protein had no regulatory effect. When the D protein was eliminated by various nonsense mutations, all other phage proteins were synthesized at rates nearl...
متن کاملGenetic Map of Bacteriophage 4 X 174
Bacteriophage 46X174 temperature-sensitive and nonsense mutations in eight cistrons were mapped by using two-, three-, and four-factor genetic crosses. The genetic map is circular with a total length of 24 X 104 wt recombinants per progeny phage. The cistron order is D-E-F-G-H-A-B-C. High negative interference is seen, consistent with a small closed circular deoxyribonucleic acid molecule as a ...
متن کاملDNA packaging intermediates of bacteriophage X 174
Background: Like many viruses, bacteriophage X174 packages its I)NA genome into a procapsid that is assembled from structural intermediates and scaffolding proteins. The procapsid contains the structural proteins F, G and H, as well as the scaffolding proteins B and D. Provirions are formed by packaging of DNA together with the small internal J proteins, while losing at least some of the B scaf...
متن کاملLINKS: Scaffolding genome assemblies with kilobase-long nanopore reads
Motivation: Owing to the complexity of the assembly problem, we do not yet have complete genome sequences. The difficulty in assembling reads into finished genomes is exacerbated by sequence repeats and the inability of short reads to capture sufficient genomic information to resolve those problematic regions. Established and emerging long read technologies show great promise in this regard, bu...
