BIOCHEMICAL CHARACTERIZATION OF A FAMILY 15 CARBOHYDRATE ESTERASE FROM A BACTERIAL MARINE ARCTIC METAGENOME.



Short germ insects utilize both the ancestral and derived mode of Polycomb group-mediated epigenetic silencing of Hox genes

In insect species that undergo long germ segmentation, such as Drosophila, all segments are specified simultaneously at the early blastoderm stage.As embryogenesis progresses, the expression boundaries of Hox genes are established by repression of gap genes, which is subsequently replaced by Polycomb group (PcG) silencing.At present, however, it is
