Prevention of degradation of RNA molecules.

The enzymatic addition of a sequence of adenylyl residues at the 3' end of an RNA molecule.

Any process that stops, prevents or reduces the frequency, rate or extent of miRNA catabolic process.

The enzymatic addition of a sequence of adenylyl residues at the 3' end of an RNA molecule.

The chemical reactions and pathways resulting in the breakdown of histone messenger RNA (mRNA).

A developmental process, independent of morphogenetic (shape) change, that is required for an oocyte to attain its fully functional state. Oocyte maturation commences after reinitiation of meiosis commonly starting with germinal vesicle breakdown, and continues up to the second meiotic arrest prior to fertilization.

The enzymatic addition of a sequence of 40-200 adenylyl residues at the 3' end of a eukaryotic mRNA primary transcript.

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 microtubule spindle during a mitotic cell cycle.

The aggregation, arrangement and bonding together of a set of components to form the spindle during a meiotic cell cycle in females. An example of this is found in Drosophila melanogaster.

The process in which the egg becomes metabolically active, initiates protein and DNA synthesis and undergoes structural changes to its cortex and/or cytoplasm.

The merging of two pronuclei in a fertilized egg to fuse and produce a single zygotic genome.

The memory process that deals with the storage, retrieval and modification of information a long time (typically weeks, months or years) after receiving that information. This type of memory is typically dependent on gene transcription regulated by second messenger activation.

Any process in which mRNA is transported to, or maintained in, a specific location within the cell.

Formation and organization of an aster composed of microtubule arrays originating from the sperm basal body and extending virtually to the egg periphery. The sperm aster ensures the appropriate positioning of the male and female pronuclei.

The directed movement of the male and female pronuclei towards each other prior to their fusion.

Prevention of degradation of RNA molecules.

The complete process of formation and maturation of an ovum or female gamete from a primordial female germ cell. Examples of this process are found in Mus musculus and Drosophila melanogaster.

The chemical reactions and pathways resulting in the breakdown of histone messenger RNA (mRNA).

Any process that stops, prevents or reduces the frequency, rate or extent of miRNA catabolic process.

The process in which precursor cell type acquires the specialized features of a hematopoietic progenitor cell, a class of cell types including myeloid progenitor cells and lymphoid progenitor cells.

The progression of the hippocampus over time from its initial formation until its mature state.

The process in which a relatively unspecialized cell acquires specialized features of a neuron.

Prevention of degradation of RNA molecules.

The enzymatic addition of a sequence of adenylyl residues at the 3' end of an RNA molecule.

The process whose specific outcome is the progression of the retina over time, from its formation to the mature structure. The retina is the innermost layer or coating at the back of the eyeball, which is sensitive to light and in which the optic nerve terminates.

The chemical reactions and pathways resulting in the breakdown of histone messenger RNA (mRNA).

The process by which the rods of the retina gradually become fully responsive to dim light when no longer exposed to bright light.

Any process that stops, prevents or reduces the frequency, rate or extent of miRNA catabolic process.

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

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.

That part of the nuclear content other than the chromosomes or the nucleolus.

A complex required for RNAi mediated heterochromatin assembly. In S. pombe this contains RNA-directed RNA polymerase, a putative helicase and a protein containing a pap25 associated domain.

A prolongation or process extending from a nerve cell, e.g. an axon or dendrite.

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.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
