Transfer gene - Wikipedia
Transfer genes or tra genes (also transfer operons or tra operons), are some genes necessary for non-sexual transfer of genetic material in both gram-positive and gram-negative bacteria. The tra locus includes the pilin gene and regulatory genes, which together form pili on the cell surface, polymeric proteins that can attach themselves to the ...
Why do mobile genetic elements transfer DNA of their hosts?
2024年11月1日 · Many instances of host DNA transfer are likely to be transient and non-adaptive. Evidence of MGE domestication suggests that host benefits of MGE-mediated sex could exist. The prokaryote world is replete with mobile genetic elements (MGEs) – self-replicating entities that can move within and between their hosts.
基因座 - 维基百科，自由的百科全书
二倍體 與 多倍體 細胞的某些染色體上，在同一基因座上有相同的等位基因，這類細胞稱為 纯合子 / 同型合子 （homozygous）。 若是相同基因座上含有不同的等位基因，則稱作 杂合子 / 異型合子 （heterozygous）。 舉例而言，一個典型的基因座可能寫成「6p21.3」，解釋如下. 區、帶和子帶是從 著絲粒 向外朝 端粒 開始編號。 基因座詳細命名規則如下： 染色體編號。 染色體上的短臂（p）或長臂（q）位置。 p 來自法文 petit (小)； q 則是選定 p 的下一個字母，也有來自法文 …

2024年10月22日 · Here, we investigate the connection between genomic motions and gene-level activity. Simultaneous mapping of single-gene and genome-wide motions shows that the coupling of gene...
Transcription and translation contribute to gene locus ... - Nature
2019年11月12日 · Transcription by RNA polymerase (RNAP) is coupled with translation in bacteria. Here, we observe the dynamics of transcription and subcellular localization of a specific gene locus (encoding a...
Migration and horizontal gene transfer divide microbial genomes …
2015年11月23日 · Horizontal gene transfer is central to microbial evolution. Here, the authors develop an eco-evolutionary model and show that migration can greatly promote horizontal gene transfer, which explains how ecologically-important loci can sweep through the species in a microbial community.
Functional and Evolutionary Characterization of a Gene Transfer …
2016年6月24日 · Gene transfer agents (GTAs) are phage-like particles that can package and transfer a random piece of the producing cell’s genome, but are unable to transfer all the genes required for their own production.
Site-specific integration and tailoring of cassette design for ...
2011年8月21日 · Analyses performed before and after integration defined features of the locus and cassette design that together allow robust transgene expression without detectable transcriptional perturbation...
Phylogenomic Simulation of Gene, Locus, and Species Trees
2015年11月1日 · We present a fast and flexible software package—SimPhy—for the simulation of multiple gene families evolving under incomplete lineage sorting, gene duplication and loss, horizontal gene transfer—all three potentially leading to species tree/gene tree discordance—and gene conversion.
PiggyBac transposase and transposon derivatives for gene transfer ...
2021年11月20日 · Genomic integrations into the rDNA is achieved at a high frequency using piggyBac. Transposon and transposase nucleolar targeting improves transgene genomic integration.
