Orientation dependence in homologous recombination.
Homologous recombination was investigated in Escherichia coli with two plasmids, each carrying the homologous region (two defective neo genes, one with an amino-end deletion and the other with a carboxyl-end deletion) in either direct or inverted orientation. Recombination efficiency was measured in recBC sbcBC and recBC sbcA strains in three ways. First, we measured the frequency of cells carr...

15 صفحه اولCentromeres
Also known as... The terms ‘centromere’ and ‘kinetochore’ are often used synonymously but it is best to consider the centromere as the DNA and chromatin on which the kinetochore is assembled and the kinetochore as the protein machine, including centromeric chromatin, which mediates attachment to the spindle. Centromeres are found near the centre of the chromosome on metacentric chromosomes, but...
متن کاملThe Synaptonemal Complex Protein Zip1 Promotes Bi-Orientation of Centromeres at Meiosis I
In meiosis I, homologous chromosomes become paired and then separate from one another to opposite poles of the spindle. In humans, errors in this process are a leading cause of birth defects, mental retardation, and infertility. In most organisms, crossing-over, or exchange, between the homologous partners provides a link that promotes their proper, bipolar, attachment to the spindle. Attachmen...
