Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.

The transfer, from NAD, of ADP-ribose to protein amino acids.

The transfer, from NAD, of ADP-ribose to protein amino acids.

Any process that activates or increases the frequency, rate, or extent of antibacterial peptide biosynthesis.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the nucleolus.

A biological process in which an animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the animal's form or structure. Examples include the change from tadpole to frog, and the change from larva to adult. An example of this is found in Drosophila melanogaster.

Polarization of the ovarian follicle cells along the dorsal/ventral axis. An example of this process is found in Drosophila melanogaster.

The synthesis of ribosomal RNA (rRNA), any RNA that forms part of the ribosomal structure, from a DNA template.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of Cajal bodies, nuclear bodies that appear ultrastructurally as a tangle of coiled, electron-dense threads roughly 0.5 micrometers in diameter and are enriched in ribonucleoproteins, and certain general RNA polymerase II transcription factors.

The decondensing (loosening) and swelling of the chromosomal sites of target genes on polytene chromosomes following response to a stimulus, to facilitate sudden bursts of transcriptional activity in response to transient environmental signals.

The decondensing (loosening) and swelling of the chromosomal sites of heat shock genes on polytene chromosomes in response to a heat shock stimulus.

The decondensing (loosening) and swelling of the chromosomal sites of heat shock genes on polytene chromosomes in response to a heat shock stimulus.

Any process that modulates the frequency, rate or extent of RNA splicing, the process of removing sections of the primary RNA transcript to remove sequences not present in the mature form of the RNA and joining the remaining sections to form the mature form of the RNA.

Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens.

A process that is carried out at the cellular level that results in the assembly, arrangement of constituent parts, or disassembly of chromosomes, structures composed of a very long molecule of DNA and associated proteins that carries hereditary information. This term covers covalent modifications at the molecular level as well as spatial relationships among the major components of a chromosome.

Any process in which a protein is maintained in the nucleus and prevented from moving elsewhere. These include sequestration within the nucleus, protein stabilization to prevent transport elsewhere and the active retrieval of proteins that escape the nucleus.

Any process that activates or increases the frequency, rate or extent of protein localization to nucleus.

A structure composed of a very long molecule of DNA and associated proteins (e.g. histones) that carries hereditary information.

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.

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.

A swelling at a site along the length of a polytene chromosome, thought to be the site of active transcription.

A swelling at a site along the length of a polytene chromosome, thought to be the site of active transcription.

The dispersed less dense form of chromatin in the interphase nucleus. It exists in at least two forms, a some being in the form of transcriptionally active chromatin which is the least condensed, while the rest is inactive euchromatin which is more condensed than active chromatin but less condensed than heterochromatin.

A small, dense body one or more of which are present in the nucleus of eukaryotic cells. It is rich in RNA and protein, is not bounded by a limiting membrane, and is not seen during mitosis. Its prime function is the transcription of the nucleolar DNA into 45S ribosomal-precursor RNA, the processing of this RNA into 5.8S, 18S, and 28S components of ribosomal RNA, and the association of these components with 5S RNA and proteins synthesized outside the nucleolus. This association results in the formation of ribonucleoprotein precursors; these pass into the cytoplasm and mature into the 40S and 60S subunits of the ribosome.

A class of nuclear body, first seen after silver staining by Ramon y Cajal in 1903, enriched in small nuclear ribonucleoproteins, and certain general RNA polymerase II transcription factors; ultrastructurally, they appear as a tangle of coiled, electron-dense threads roughly 0.5 micrometers in diameter; involved in aspects of snRNP biogenesis; the protein coilin serves as a marker for Cajal bodies. Some argue that Cajal bodies are the sites for preassembly of transcriptosomes, unitary particles involved in transcription and processing of RNA.

A nuclear body associated with the histone gene locus that is thought to contain all of the factors necessary for histone mRNA transcription and pre-mRNA processing. In Drosophila, U7 snRNP is located in the histone locus body rather than the distinct Cajal body.
