The process whose specific outcome is the progression of the embryo in the uterus over time, from formation of the zygote in the oviduct, to birth [goid 1701] [evidence IEA]; The process whereby a precursor cell type acquires the specialized features of a pro-B cell. Pro-B cells are the earliest stage of the B cell lineage and undergo heavy chain D and J gene rearrangements, although they are not fully committed [goid 2328] [evidence IEA]; The repair of double-strand breaks in DNA via homologous and nonhomologous mechanisms to reform a continuous DNA helix [goid 6302] [evidence IEA]; The repair of a double-strand break in DNA in which the two broken ends are rejoined with little or no sequence complementarity. Information at the DNA ends may be lost due to the modification of broken DNA ends [goid 6303] [pmid 12517771] [evidence IDA]; The repair of a double-strand break in DNA in which the two broken ends are rejoined with little or no sequence complementarity. Information at the DNA ends may be lost due to the modification of broken DNA ends [goid 6303] [pmid 9809069] [evidence IMP]; The repair of a double-strand break in DNA in which the two broken ends are rejoined with little or no sequence complementarity. Information at the DNA ends may be lost due to the modification of broken DNA ends [goid 6303] [pmid 16439205] [evidence NAS]; The process whose specific outcome is the progression of the central nervous system over time, from its formation to the mature structure. The central nervous system is the core nervous system that serves an integrating and coordinating function. In vertebrates it consists of the brain, spinal cord and spinal nerves. In those invertebrates with a central nervous system it typically consists of a brain, cerebral ganglia and a nerve cord [goid 7417] [evidence IEA]; A change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of X-ray radiation. An X-ray is a form of electromagnetic radiation with a wavelength in the range of 10 nanometers to 100 picometers (corresponding to frequencies in the range 30 PHz to 3 EHz) [goid 10165] [evidence IEA]; A change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of X-ray radiation. An X-ray is a form of electromagnetic radiation with a wavelength in the range of 10 nanometers to 100 picometers (corresponding to frequencies in the range 30 PHz to 3 EHz) [goid 10165] [pmid 9242410] [evidence IDA]; A change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of X-ray radiation. An X-ray is a form of electromagnetic radiation with a wavelength in the range of 10 nanometers to 100 picometers (corresponding to frequencies in the range 30 PHz to 3 EHz) [goid 10165] [evidence IEA]; A change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a gamma radiation stimulus. Gamma radiation is a form of electromagnetic radiation (EMR) or light emission of a specific frequency produced from sub-atomic particle interaction, such as electron-positron annihilation and radioactive decay. Gamma rays are generally characterized as EMR having the highest frequency and energy, and also the shortest wavelength, within the electromagnetic radiation spectrum [goid 10332] [evidence IEA]; The molecular events that lead to the integration of a viral genome into the host genome [goid 19047] [pmid 16291214] [evidence EXP]; The set of processes involved in the start of virus infection of cells [goid 19059] [pmid 12091904] [evidence EXP]; The process whereby a precursor cell type acquires the specialized features of a T cell via a differentiation pathway dependent upon transit through the thymus [goid 33077] [evidence IEA]; The process by which immunoglobulin heavy chain V, D, and J gene segments are recombined within a single locus utilizing the conserved heptamer and nonomer recombination signal sequences (RSS). For immunoglobulin light chains the same process is used to join V and J gene segments directly [goid 33152] [evidence IEA]; Any process that stops, prevents or reduces the frequency, rate or extent of cell death by apoptosis in neurons [goid 43524] [evidence IEA]; Any process that activates or increases the frequency, rate or extent of multiplication or reproduction of fibroblast cells [goid 48146] [evidence IEA]; Any process that activates or increases the frequency, rate or extent of neurogenesis, the origin and formation of neurons [goid 50769] [evidence IEA]; The re-formation of a broken phosphodiester bond in the DNA backbone, carried out by DNA ligase, as occurs during DNA repair [goid 51103] [pmid 12517771] [evidence IDA]; Any process that activates or increases the frequency, rate or extent of ligase activity, the catalysis of the ligation of two substances with concomitant breaking of a diphosphate linkage, usually in a nucleoside triphosphate [goid 51351] [pmid 9242410] [evidence IDA]
