单词 | transposon |
例句 | There is evidence of repeating genetic code near the spots where genes are missing, which might point to transposon activity, Dr. Small said. ‘Evolution Gone Crazy’: What Makes Sea Dragons So Strange 2022-07-07T04:00:00Z In 2021 Wang discovered a transposon that activates a critical gene in mouse embryos; delete that single transposon, and many of the embryos die. Junk DNA Deforms Salamander Bodies 2022-02-02T05:00:00Z That study suggested that the virus-based transposon has been "broadly repurposed" by other mammals including humans. Far from evil, viruses have driven — and even helped — human evolution 2021-12-03T05:00:00Z In the species with sterile workers, older workers have higher transposon activity; in the species where older workers can reproduce, they show better defense against damage from transposons. What can ants, bees, and other social insects teach us about aging? 2021-03-25T04:00:00Z It was caused by a jumping gene, or transposon, a sequence of nucleotides that replicates and moves to a spot in the genome where it does not belong. A Breakthrough in Genetic Medicine for Rare Diseases 2020-03-23T04:00:00Z Perhaps most notably, the authors find that the ZnB wings move constantly: they unfurl when transposon DNA first arrives, and then close and open again during the rest of the process. Snapshots of a genetic cut-and-paste 2019-11-12T05:00:00Z A newly inserted transposon won’t be passed on to the next generation if it causes its host to be sterile, for example. Junk DNA Deforms Salamander Bodies 2022-02-02T05:00:00Z They show that the transposon can use the RNA-guided component of its Cascade passenger to direct Cascade to a particular position in a genome. Hijack of CRISPR defences by selfish genes holds clinical promise 2019-06-11T04:00:00Z By helping its host cells, Feschotte says, the transposon achieves its selfish ends. Don’t call it junk—This ‘jumping’ gene may be why you made it past an embryo 2018-06-21T04:00:00Z Discrete small RNA-generating loci as master regulators of transposon activity in Drosophila. piRNA-mediated regulation of transposon alternative splicing in the soma and germ line 2017-12-05T05:00:00Z Genome-wide transposon screening and quantitative insertion site sequencing for cancer gene discovery in mice. PD-1 is a haploinsufficient suppressor of T cell lymphomagenesis 2017-11-14T05:00:00Z She and her colleagues found Karma, a mobile piece of DNA known as a transposon, inserted in the middle of an important gene for normal oil-palm fruit development called DEFICIENS. A makeover for the world's most hated crop 2017-03-14T04:00:00Z The protein products of these genes work together to insert the transposon DNA into a specific spot in a bacterium’s genome at which insertion does not harm the host. Hijack of CRISPR defences by selfish genes holds clinical promise 2019-06-11T04:00:00Z The repeats were used to reconstruct full-length subgenome specific transposon sequences. Genome evolution in the allotetraploid frog Xenopus laevis : Nature : Nature Research 2016-10-18T04:00:00Z Adaptation to P element transposon invasion in Drosophila melanogaster. piRNA-mediated regulation of transposon alternative splicing in the soma and germ line 2017-12-05T05:00:00Z As large-scale expansion and movement of transposable elements are known to increase under genomic stress24, this may suggest that Ss4R caused transposable element expansion by compromising regulatory processes responsible for transposon policing. The Atlantic salmon genome provides insights into rediploidization : Nature : Nature Publishing Group 2016-04-17T04:00:00Z This correlation may reflect modulation of gene expression by transposon-derived enhancers or a greater tolerance for transposon insertion near genes with less complex patterns of tissue-specific gene regulation. The octopus genome and the evolution of cephalopod neural and morphological novelties : Nature : Nature Publishing Group 2015-08-11T04:00:00Z The transposon thus becomes a permanent ‘passenger’ in that bacterium. Hijack of CRISPR defences by selfish genes holds clinical promise 2019-06-11T04:00:00Z Open rectangles are genes that do not overlap transposon sequences; filled black rectangles represent genes overlapping transposon sequences. Patterns of population epigenomic diversity 2013-03-13T18:21:41.540Z This suggests that beyond transposon control, the piRNA pathway may play a more general role in cellular gene regulation. [Research Article] Identification of Functional Elements and Regulatory Circuits by Drosophila modENCODE 2011-01-05T15:57:51.363Z "Forty-five percent of the genome is known to be transposon sequences," Devine said. "Jumping genes" make each person unique: study 2010-06-24T20:27:00Z This insertion is impressively specific — in all 25 cases studied by the authors, the transposon was delivered precisely and exclusively to the targeted address in the bacterial genome. Hijack of CRISPR defences by selfish genes holds clinical promise 2019-06-11T04:00:00Z One type of mobile element is called a transposon. Hijack of CRISPR defences by selfish genes holds clinical promise 2019-06-11T04:00:00Z Open rectangles are genes that do not overlap transposon sequences; filled black rectangles represent genes overlapping transposon sequences. Patterns of population epigenomic diversity 2013-03-13T18:21:41.540Z Cascade is directed to a chromosome by a guide RNA, but then binds a transposase-associated protein, TniQ, which in turn recruits the transposon and integrates it into the chromosome. Hijack of CRISPR defences by selfish genes holds clinical promise 2019-06-11T04:00:00Z |
