Retrotransposons (also called Class I transposable elements or transposons via RNA intermediates) are a type of genetic component that copy and paste themselves into different genomic locations (transposon) by converting RNA back into DNA through the reverse transcription process using an RNA transposition intermediate. (wikipedia.org)
In addition to having a role in the suppression of genomic transposons, various roles of piRNAs have been recently reported like regulation of 3' UTR of protein-coding genes via RNAi, transgenerational epigenetic inheritance to convey a memory of past transposon activity, and RNA-induced epigenetic silencing.

The 576-aa DEAF-1 protein possesses two conserved domains, SAND and MYND. (sdbonline.org)
The 32-aa MYND domain (for myeloid, Nervy, and Deaf-1) contains non-DNA-binding zinc fingers that are thought to mediate protein-protein interactions (Gross, 1996). (sdbonline.org)
DEAF-1 is maternally expressed, and the encoded protein is broadly distributed throughout the early embryo. (sdbonline.org)
and results in the formation of a large nucleo-protein complex (the partition complex) around the parS site on the DNA to be partitioned. (biorxiv.org)
The normal RUNX1 protein, produced from the RUNX1 gene, is part of a protein complex called core binding factor (CBF) that attaches (binds) to DNA and turns on genes involved in blood cell development. (medlineplus.gov)
The normal ETO protein, produced from the RUNX1T1 gene, turns off gene activity. (medlineplus.gov)
The RUNX1-ETO fusion protein forms CBF and attaches to DNA, but instead of turning on genes that stimulate the development of blood cells, it turns those genes off. (medlineplus.gov)
It contained 128 genes (83 protein-coding genes, eight rRNAs, and 37 tRNAs). (e-kjpt.org)

To uncover the causes of drug interactions, we developed a systematic approach based on precise quantification of the individual and joint effects of antibiotics on growth of genome-wide Escherichia coli gene deletion strains. (embopress.org)
There is no cross-reactivity with non-tuberculous mycobacteria, and TB and rifampicin resistance were correctly detected in the presence of non-tuberculous DNA or mixed susceptible and resistant strains. (bvsalud.org)

We extracted viral DNA from the 7 organ and 2 fluid samples by using the IndiMag Pathogen Kit (Indical Bioscience GmbH, https://www.indical.com ), according to the manufacturer's guidelines. (cdc.gov)

One individual was found to carry a 12 kb deletion in one copy of the ASPA gene on 17p13, which when mutated in both alleles leads to Canavan disease. (biomedcentral.com)

We first determined the level of total CYP2A13 mRNA in 18 normal lung biopsy tissues to assess the extent of interindividual variation. (aspetjournals.org)

A recent study using a rat model found significant differences at the time of diabetes onset in the bacterial communities responsible for type 1 diabetes modulation. (biomedcentral.com)
In the children with diabetes, the bacterial number of Actinobacteria and Firmicutes, and the Firmicutes to Bacteroidetes ratio were all significantly decreased, with the quantity of Bacteroidetes significantly increased with respect to healthy children. (biomedcentral.com)
Culture-based investigations of a small number of bacterial taxa have indicated that exposure to light, and especially ultraviolet (UV) wavelengths [ 16 , 22 - 25 ], can inactivate many microorganisms and therefore potentially reduce dust microbial community viability. (biomedcentral.com)

These genes overlap so they encode a protease that processes the resulting transcript into functional gene products. (wikipedia.org)
A similar trait-specific gene prioritization strategy could be employed to help streamline functional validation experiments for virtually any human trait. (biomedcentral.com)
but only two of these, an Arg101Stop mutation in exon 2, and an Arg257Cys variation in exon 5, are known to have functional consequences. (aspetjournals.org)
In total, 13,134 functional genes were annotated, accounting for 94.97% of the total gene number. (researchsquare.com)
However, there are few in-depth studies on the functional genes. (researchsquare.com)

The assembly included 16 fragments with a GC content of 48.01%, gap number of zero, and size of 40,776,005 bp. (researchsquare.com)
Control DNA substrates are synthetic 100 bp double stranded fragments containing a single MspI/HpaII site (CCGG). (neb.com)
Nous avons génotypé les deux polymorphismes mononucléotidiques du gène ADIPOQ chez 140 patients atteints de DNID sans lien de parenté et 66 témoins non diabétiques en recourant à l'analyse du polymorphisme de longueur des fragments de restriction par réaction en chaîne de polymérase. (who.int)

Approximately 20 genes consistently associated with T2DM mainly implicate pancreatic β-cell function in the pathogenesis of T2DM. (scialert.net)
Recent studies have highlighted the potential role of infection in the pathogenesis of IPF and a prior association of the HLA-DQB1 gene with idiopathic fibrotic interstitial pneumonia (including IPF) has been reported. (bvsalud.org)

Long strands of repetitive DNA can be found at each end of a LTR retrotransposon. (wikipedia.org)
This level of heat causes the DNA strand to separate from its antiparallel double helix into two individual strands. (openwetware.org)
This temperature cools the DNA, making the strands want to come back together. (openwetware.org)
Final Hold: 4°C. Lowered temperatures cause the individual strands to come back together to form a full double helical DNA strand. (openwetware.org)

Andy covered work to improve sensitivity in an effort to reduce the input requirements of the system, an aspect that is crucial to detecting the minute quantities of DNA that result from specific enrichment. (nanoporetech.com)
Results from analytical studies showed that the Xpert MTB/RIF assay has analytic sensitivity of five genome copies of purified DNA, and 131 cfu/ml of M. tuberculosis spiked into sputum. (bvsalud.org)

We are currently pursuing studies of the dominant signaling and gene regulatory networks that control this process, including the Ras/MAPK cascade, which is required for stem cell-mediated self-renewal and the p53 transcription factor family member, p63, which is required for epidermal differentiation.
