What are the factors that influence the bias of 16S rRNA gene ampicon sequencing?

What are the factors that contribute to coverage bias in amplicon sequencing?4 answersCoverage bias in amplicon sequencing can be influenced by several factors. These include differences in 3′-end stability, primer Tm, amplicon length, amplicon GC content, and GC content of amplicon flanking regions. The presence of a highly dominant taxon…

Learning the rules of the Scrabble game behind lymphocyte diversity

Reporter, terrier, retire, retro, port, trio, toe. What do these seemingly random words have in common? They can all be formed from bits and pieces of the word repertoire (hats off to any Scrabble fans in the audience). This concept—of adding, deleting, and rearranging the letters of a fixed character…

Elasmobranch genome sequencing reveals evolutionary trends of vertebrate karyotypic organization

↵* Corresponding author; email: skuraku{at}nig.ac.jp Abstract Genomic studies of vertebrate chromosome evolution have long been hindered by the scarcity of chromosome-scale DNA sequences of some key taxa. One of those limiting taxa has been the elasmobranchs (sharks and rays), which harbor species often with numerous chromosomes and enlarged genomes. Here,…

what is gene synthesis used for

As the resulting plasmid contains the original prefix and suffix sequences, it can be used to join with more BioBricks parts. The development of the Golden Gate assembly methods and its variants has allowed researchers to design tool-kits to speed up the synthetic biology workflow. By using the BsaI restriction…

Amplification Biases and Consistent Recovery of Loci in a Double-Digest RAD-seq Protocol | PLOS ONE – Molecular Biology Protocol – Restriction Digest of Plasmid …

Abstract A waxing variety of “genotype-by-sequencing” (GBS) methods use restriction enzymes and high throughput DNA ordering to generation data for a set of genomic loci, allowing the simultaneous discovery press genotyping of thousands of polymorphisms in a set of multiplexed samples. We evaluated a “double-digest” restriction-site associated DNA sequencing (ddRAD-seq)…

Gut taste receptor type 1 member 3 is an intrinsic regulator of Western diet-induced intestinal inflammation | BMC Medicine

Study design The objective of the study was to evaluate the influence of long-term WD intake on intestinal inflammation and investigate possible mechanisms by which WD intake could affect IBD development. To this end, mice were fed normal diet (ND) or WD for 10 weeks, and bowel inflammation was evaluated through…
