Abstract:

In this thesis, I describe the development of a single-molecule platform for analysing long DNA molecules that captures haplotype and large-scale structural variation (SV) in addition to DNA sequence. Cunent DNA sequencing methods cannot adequately examine haplotype and SV - both contribute to biological function and disease and are candidates for the location of "missing heritability" in the genome. Both haplotype and SV fundamentally relate to the structure of single chromosomes. Using a lab-on-a-chip nanofluidic device, SV was analysed on stretched (> 2 Mb) DNA fragments. In order to integr

The long-range structure of the Y chromosome alphoid satellite DNA has been determined in the cell lines 3E7 and OXEN. Variation in alphoid DNA block size and restriction enzyme sites were observed. The alphoid block size and restriction enzyme site variations were determined for a collection of 42 normal Y chromosomes. The alphoid DNA polymorphisms observed denned 24 Y chromosome alleles. Unexpectedly, the Y alphoid DNA alleles analysed revealed two distinct groups of Y chromosomes indicating that most of the Caucasian and Asian men analysed were descended from one of two males.

Abstract:

The integrity of the genome relies on the maintenance of chromosomes, the structural embodiment of the genetic material. Disruption of chromosome replication can lead to extensive genomic rearrangements, spanning kilobase (Kb) to megabase (Mb) regions. Some chromosome rearrangements are inherently dynamic, beginning as a single unstable rearrangement from which multiple rearrangements emerge. The rare formation and transient behavior of unstable chromosomes renders their study challenging. Here I characterize the genetic ontogeny of unstable chromosomes in a budding yeast model, from initial r

Abstract:

Microsatellites are simple repetitive DNA sequences that are used as genetic markers throughout the biological sciences. The high levels of variation observed at microsatellite loci contribute to their utility in studies at the population and individual levels. This variation is a consequence of mutations that change the length of microsatellite repeat tracts. Current understanding suggests that most mutations are caused by polymerase slippage during DNA replication and lead to changes of a single repeat unit in length, but some changes involving multiple repeats can also occur.

Esses possuem o cisto espermatogonial envolto pelas células císticas, as quais desenvolvem a função de nutrição das células em divisão celular. Quanto às características citogenéticas, esses insetos apresentam cromossomos holocinéticos, baixa variabilidade cariotípica e meiose invertida dos cromossomos sexuais. No presente trabalho foram caracterizadas as células císticas

Abstract:

Human response to ionising radiation (IR) shows a wide variation. This is most clearly seen in the radiation-response of cells as measured by frequencies of chromosomal aberrations. Different frequencies of IR-induced aberrations can be conveniently observed in phytohaemagglutin-stimulated peripheral blood T-lymphocytes from both normal individuals and sporadic cancer cases, in either metaphase chromosomes or as micronuclei in the following cell cycle. Metaphase cells show frequent chromatid breaks, defined as chromatid discontinuities or terminal deletions, if irradiated in the G 2 -phase of

Abstract:

Increased mutagenesis is a hallmark of cancers. On the other hand, this can trigger the generation of polymorphisms and lead to evolution. Lately, it has become clear that one of the major sources of increased mutation rates in the genome is chromosomal break formation and repair. A variety of factors can contribute to the generation of breaks in the genome. A paradoxical source of breaks is the sequence composition of the genomic DNA itself. Eukaryotic and prokaryotic genomes contain sequence motifs capable of adopting secondary structures often found to be potent inducers of double str

Abstract:

Die Verbindung von genetischen, physikalischen und zytologischen Daten ist entscheidend für die Genom- und Chromosomenanalyse. Obwohl Beta vulgaris (2n = 18) als wichtige Kulturpflanze und Untersuchungsobjekt der Grundlagenforschung eine intensiv analysierte Art darstellt, existiert bisher keine Verknüpfung zwischen Kopplungsgruppen (LG) und Chromosomen. B.-vulgaris-Chromosomen können zudem aufgrund fehlender morphologischer Unterscheidungsmerkmale bisher nicht einzeln identifiziert und klassifiziert werden. Somit sind zytogenetisch gewonnene Ergebnisse nicht ohne weiteres auf genetische Koppl
