Any process that stops, prevents, or reduces the frequency, rate or extent of transcription mediated by RNA polymerase II.

A cell cycle process that modulates the rate or extent of the progression through the preblastoderm mitotic cell cycle.

The expansion of a neuroblast population by cell division. A neuroblast is any cell that will divide and give rise to a neuron.

Any process that stops, prevents or reduces the rate or extent of cell proliferation.

Any process that decreases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA or circRNA (for protein-coding genes) and the translation of that mRNA or circRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.

The directed movement of nuclei within the syncytial embryo of insects. These precise temporal and spatial patterns of nuclear movement are coordinated with mitotic divisons and are required during blastoderm formation to reposition dividing nuclei from the interior of the syncytial embryo to the cortex.

The process whose specific outcome is the progression of an immature germ cell over time, from its formation to the mature structure (gamete). A germ cell is any reproductive cell in a multicellular organism.

Any process that mediates the adoption of a specific fate by a cell.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

A type of chromosome in a polyploid cell, formed when multiple copies of homologous chromosomes are aligned side by side to give a giant chromosome in which distinct chromosome bands are readily visible.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

A multisubunit complex consisting of Myb and other proteins that regulates site specific DNA replication, gene amplification and transcriptional repression.
