Point Mutation Rate of Bacteriophage ΦX174 [PDF]

open access: yesGenetics, 2009
Abstract The point mutation rate of phage ΦX174 was determined using the fluctuation test. After identifying the genetic changes associated with the selected phenotype, we obtained an estimate of 1.0 × 10−6 substitutions per base per round of copying, which is consistent with Drake's rule (0.003 mutations per genome per round of copying ...

Effects of Somatic Mutations Are Associated with SNP in the Progression of Individual Acute Myeloid Leukemia Patient: The Two-Hit Theory Explains Inherited Predisposition to Pathogenesis [PDF]

open access: yesGenomics & Informatics, 2013
This study evaluated the effects of somatic mutations and single nucleotide polymorphisms (SNPs) on disease progression and tried to verify the two-hit theory in cancer pathogenesis.

Hot-Spot-Specific Probe (HSSP) for Rapid and Accurate Detection of KRAS Mutations in Colorectal Cancer

open access: yesBiosensors, 2022
Detection of oncogene mutations has significance for early diagnosis, customized treatment, treatment progression, and drug resistance monitoring. Here, we introduce a rapid, sensitive, and specific mutation detection assay based on the hot-spot-specific

A SIMPLE pipeline for mapping point mutations [PDF]

open access: yesPlant Physiology, 2016
Abstract A forward genetic screen is one of the best methods for revealing the regulatory functions of genes. In plants, this technique is highly efficient since it is relatively easy to grow and screen the phenotypes of hundreds or thousands of individuals.

Molecular monitoring of the Leu-164 mutation of dihydrofolate reductase in a highly sulfadoxine/pyrimethamine-resistant area in Africa. [PDF]

open access: yes, 2003
The selection of point mutation at codon 164 (from isoleucine to leucine) of the dihydrofolate reductase (DHFR) enzyme in Plasmodium falciparum is associated with high sulfadoxine /pyrimethamine (SP) resistance.

Functional Characterization of the Arabidopsis Ammonium Transporter AtAMT1;3 With the Emphasis on Structural Determinants of Substrate Binding and Permeation Properties

open access: yesFrontiers in Plant Science, 2020
AtAMT1;3 is a major contributor to high-affinity ammonium uptake in Arabidopsis roots. Using a stable electrophysiological recording strategy, we demonstrate in Xenopus laevis oocytes that AtAMT1;3 functions as a typical high-affinity NH4+ uniporter ...

KRAS mutation analysis by PCR : a comparison of two methods [PDF]

open access: yes, 2015
Background: KRAS mutation assays are important companion diagnostic tests to guide anti-EGFR antibody treatment of metastatic colorectal cancer. Direct comparison of newer diagnostic methods with existing methods is an important part of validation of ...

Site-directed mutagenesis of cysteine to serine residues affects heparin binding and mitogenicity in fibroblast growth factor 4 produced in Escherichia coli

open access: yesBiotechnology & Biotechnological Equipment, 2019
The binding activity to heparan sulphate is crucial for the mitogenic activity of fibroblast growth factor 4 (FGF4) in developing mammalian embryos. There are two conserved cysteine residues in FGF family proteins, Cys-84 and Cys-151 in mouse FGF4, and ...
