Molecular drive and population differentiation of satellite DNAs in Cyprinodon variegatus
… contains at least two highly repetitive satellite DNA sequences. The major satellite sequence is present at roughly 10<sup>6</sup> copies per haploid genome. The basic repeating unit averages 170 bp in length, tandemly arranged, and is bracketed by a Hind III restriction site. The Hind …

Detection of Bacterial Retroelements Using Genomics
… of genetic information can occur when a special DNA polymerase called Reverse Transcriptase (RT) copies the genetic information in an RNA molecule back into a complementary DNA. One type of RT encoding gene found in bacteria is called a retron element. Recent bacterial genome sequencing projects …

Discovery and engineering of antiviral defense systems in bacteria and archaea
… defense, including RNA editing and retron satellite DNA synthesis. In addition, we predict a diverse set of other putative defense genes that remain to be characterized. These results highlight an immense array of molecular functions that bacteria and archaea employ against viruses.

Interrogating Dux4 Mrna 3′ End Processing
… a single nucleotide polymorphism in the flanking DNA that generates a non-consensus polyadenylation signal (PAS). This PAS allows for the productive transcription of a polyadenylated Dux4 mRNA from the terminal D4Z4 repeat. Dux4 is anemically expressed in patient somatic cells, but contributes to …

Sequence and Functional Structures of the Extrachromosomal rDNA Minichromosome of Physrum Polycephalum
… copies of linear, palindromic extrachromosomal DNA molecules (rDNA), which have been isolated both as a satellite DNA molecule, and as a "minichromosome" with associated chromatin proteins. The genes coding for the 19 S, 26 S, and 5.8 S rRNAs are transcribed as a single, large precursor …

Chromosome evolution and mechanisms of speciation in the Anopheles gambiae complex
… autosome and sex chromosome repetitive DNA differs among sibling species of An. gambiae complex with highly similarity between An. coluzzii and An. arabiensis. In addition, heterochromatin blocks of chromosomes have distinct compositions of satellite DNA sequences. Next, in order to …

Molecular-cytogenetic analysis of repetitive sequences in genomes of Beta species and hybrids
… beet Beta vulgaris has a genome size of 758 Mbp DNA with estimated 63 % repetitive sequences and the number of chromosomes n=9. The wild beet Beta procumbens is an important natural pool of resistance against pests and tolerance to unfavorable growth conditions. The subject of this research was …

Comparative Analysis of Heterochromatin in the Anopheles gambiae Complex
… in members of the An. gambiae complex. Specific satellite DNA and 18S ribosomal DNA probes (major components of heterochromatin) were mapped to X chromosomes enabling their differentiation and characterization in the An. gambiae complex. Microarray studies have highlighted the importance of X …

Rekonstrukce repetitivních elementů DNA
… práce obsahuje hlavní klasifikaci repetitivní DNA a představuje implementaci nového de novo assembleru, zaměřeného na hledání a sestavení LTR retrotranspozonů a satelitní DNA. Assembler přijímá na svém vstupu krátké ready (single nebo pair-end), získané sekvenátory druhé generace (NGS). Tento …
