Chromosomal fragments were found without canonical centromere sequences, revealing de novo centromere formation over unique sequences; these were validated by immunolocalization with Thr133-phosphorylated histone H2A, a marker of active centromeres, and chromatin immunoprecipitation-sequencing with the CENH3 antibody. Acentric fragments are commonly generated by chromosome-breaking events, such as irradiation. Such acentric fragments are unequally distributed between the daughter cells after cell division. Acentric fragments can also be produced when an inverted segment is present in one member of a chromosome pair. In that case, a crossover event will result in one chromosome with two centromeres and an acentric fragment. Chromosome fragmentation (C-Frag) is a newly identified MCD (mitotic cell death), distinct from apoptosis and MC (mitotic catastrophe). As different molecular mechanisms can induce C-Frag, we The loss of a fragment of a chromosome.

Fragmented chromosome

4D,I). At diakinesis, separated chromosomes and fragments could be clearly distinguished (Fig. 4E,J ). 2008-10-29 · Background The phylogeography of the Y chromosome in Asia previously suggested that modern humans of African origin initially settled in mainland southern East Asia, and about 25,000–30,000 years ago, migrated northward, spreading throughout East Asia.

and extensively fragmented chromosomes. The ciliate cell cycle During vegetative growth, characterized by a lack of sexual conjugation, the MAC generates all transcripts needed for protein synthesis. Experiments involving amicronucleated ciliates have shown that some ciliates like Tetrahymena can survive and continue However, fragmented chromosomes produced by breakage of dicentric chromosomes or by P-element transposase (L evis 1989) must evade this response mechanism.

1997), such chromosomes are recovered more frequently after irradiation of mu2 females (M ason et al. 1984), or after P-element mobilization (L evis 1989). This suggests that the method by which a chromosome is broken might influence the consequences of that break. Among the A-chromosome variants with A-centromere changes, there are fragments containing different sizes of A-centromeric regions, dicentric chromosomes with two primary constrictions, chromosomes with only one primary constriction but two sets of centromeric sequences, and A chromosomes containing three or more centromeric-sequence–containing regions (Figure 2; Table 1; Supplemental Figure 4; Supplemental Data Set). Chromosomal fragments were found without canonical centromere sequences, revealing de novo centromere formation over unique sequences; these were validated by immunolocalization with Thr133-phosphorylated histone H2A, a marker of active centromeres, and chromatin immunoprecipitation-sequencing with the CENH3 antibody.

The mechanism of chromosome breakage may play a role in stimulation of a checkpoint response. Chromosomal fragments were found without canonical centromere sequences, revealing de novo centromere formation over unique sequences; these were validated by immunolocalization with Thr133-phosphorylated histone H2A, a marker of active centromeres, and chromatin immunoprecipitation-sequencing with the CENH3 antibody. Among the A-chromosome variants with A-centromere changes, there are fragments containing different sizes of A-centromeric regions, dicentric chromosomes with two primary constrictions, chromosomes with only one primary constriction but two sets of centromeric sequences, and A chromosomes containing three or more centromeric-sequence–containing regions (Figure 2; Table 1; Supplemental Figure 4; Supplemental Data Set).

Kromosomfragment in English with contextual examples

A chromosome mutation that causes individuals to have an abnormal number of chromosomes is termed aneuploidy. Aneuploid cells occur as a result of chromosome breakage or nondisjunction errors that happen during meiosis or mitosis. Nondisjunction is the failure of homologous chromosomes to separate properly during cell division.

One cell with 46 chromosomes divides and becomes two cells with 46 chromosomes each. This kind of cell division occurs throughout the body, except in the reproductive organs. This is the way most of the cells that make up our body are made and replaced. A chromosome mutation that causes individuals to have an abnormal number of chromosomes is termed aneuploidy. Aneuploid cells occur as a result of chromosome breakage or nondisjunction errors that happen during meiosis or mitosis. Nondisjunction is the failure of homologous chromosomes to separate properly during cell division.

The method is useful in analyzing cells for the occurrence of chromosomes, chromosome fragments or chromosome aberrations. The chromosome fragments survived as a result of a nonlocalized centromere. Free chromosome fragments are created through irradiation/other damage of the germline in one animal.
