DOI: 10.1534/genetics.119.302978
Abstract: In eukaryotic cells, the spatial organization of genes within the nucleus is correlated with their expression. However, correlation is not causa-tion. To determine how nuclear spatial organization affects gene expression, Di Stefano et al. studied...… read more here.

DOI: 10.24272/j.issn.2095-8137.2022.386
Abstract: What is the minimum number of chromosomes that a eukaryotic species can tolerate? This question has long fascinated biologists as chromosomal rearrangements are associated with both speciation and various genetic diseases. Nature already has an… read more here.
