DNA size markers (ladder) are essential tools in molecular biology, genetics and biotechnology. In this study, a simple and cost-effective method for laboratory production of DNA ladders is introduced. For this purpose, different sizes of 100 to 2000 bp DNA segments were designed using PCR technique. For producing 14 different gene fragments as DNA molecular weight markers, recombinant plasmid ...

We developed a novel method for synthesizing marker-disrupted alleles of yeast genes. The first step is PCR amplification of two sequences located upstream and downstream of the reading frame to be disrupted. Due to the addition of non-specific single A overhangs by Taq DNA polymerase, each PCR product can be ligated with a marker DNA which has T residues at its 3' ends. After amplification of ...

Evaluation of eating quality in early breeding generations of rice is critical to developing varieties with better palatability. This paper reports DNA markers associated with eating quality of temperate japonica rice and an evaluation method aided by multiple regression analysis. A total of 30 markers comprising STSs, SNPs, and SSRs were tested for their association with palatability using 22 ...

RAPD-PCR genetic markers were used to assess variation in wheat plants and connections among six genotypes. Four random primers produced 140 DNA fragments, averaging 6.7 identifiable bands per primer. Among the genotypes, 85 pieces (44.64 percent) polymorphic. Several RAPD marker had distinct signify recurrence patterns that thing differently amongst germplasm of groupings. Within-community acc...

Information regarding Coronavirus disease 2019 in the transplant population is lacking. Recently it has been suggested that cycle threshold values obtained on polymerase chain reaction tests may serve as a marker of severity with lower (i.e., higher viral load) being associated mortality. This study was done to assess impact remdesivir use time negative COVID-19 PCR well degree change between t...

Arbitrarily-primed DNA markers can be very useful for genetic fingerprinting and for facilitating positional cloning of genes. This class of technologies is particularly important for less studied species, for which genome sequence information is generally not known. The technologies include Randomly Amplified Polymorphic DNA (RAPD), DNA Amplification Fingerprinting (DAF), and Amplified Fragmen...

Native diversity is well represented in northern and eastern parts of India for mango. We evaluated three important polymerase chain reaction (PCR) based marker techniques viz., random amplified polymorphic DNA (RAPD), inter simple sequence repeat (ISSR) and directed amplified mini satellite DNA (DAMD) and examined their suitability for depicting genetic relationships and discrimination among c...
