recommendations! Published in 2019 at "Journal of Molecular Evolution"

DOI: 10.1007/s00239-019-09909-0

Abstract: The sea lamprey (Petromyzon marinus) undergoes substantial genomic alterations during embryogenesis in which specific sequences are deleted from the genome of somatic cells yet retained in cells of the germ line. One element that undergoes… read more here.

DOI: 10.1016/j.ceb.2017.03.004

Abstract: Nucleoli, sites of ribosome biogenesis, form around nucleolar organizer regions (NORs) comprising rDNA arrays, located on human acrocentric chromosome p-arms. NORs provide an opportunity to investigate the DNA double strand break (DSB) response at highly… read more here.

DOI: 10.1016/j.jsb.2019.08.010

Abstract: Spatial organisation of chromosomes is a determinant of genome stability and is required for proper mitotic segregation. However, visualization of individual chromatids in living cells and quantification of their geometry, remains technically challenging. Here, we… read more here.

DOI: 10.1016/j.micres.2021.126764

Abstract: Efficient expression vectors for unicellular ciliate eukaryotic Tetrahymena thermophila are still needed in recombinant biology and biotechnology applications. Previously, the construction of the T. thermophila Macronuclear Artificial Chromosome 1 (TtAC1) vector revealed additional needs for… read more here.
