The replication of a centrosome, a structure comprised of a pair of centrioles and peri-centriolar material from which a microtubule spindle apparatus is organized.

The process by which duplicated centrosome components move away from each other. The centriole pair within each centrosome becomes part of a separate microtubule organizing center that nucleates a radial array of microtubules called an aster. The two asters move to opposite sides of the nucleus to form the two poles of the mitotic spindle.

assembly of spliceosomal tri-snRNP U4/U6.U5

The formation of a tri-snRNP complex containing the U4, U6, and U5 snRNAs and associated proteins. This includes reannealing of U4 and U6 snRNAs released from previous rounds of splicing to reform the U4/U6 snRNP as well as the subsequent association of the U5 snRNP with the U4/U6 snRNP to form the tri-snRNP that is ready to reassemble into another U2-type spliceosome complex.

oxidoreductase activity, acting on the CH-NH2 group of donors, oxygen as acceptor

Catalysis of an oxidation-reduction (redox) reaction in which a CH-NH2 group acts as a hydrogen or electron donor and reduces an oxygen molecule.

The formation from simpler components of a protein, rather than of proteins in general.

oxidoreductase activity, acting on the CH-NH2 group of donors, disulfide as acceptor

oxidoreductase activity, acting on the CH-NH2 group of donors, disulphide as acceptor

Catalysis of an oxidation-reduction (redox) reaction in which a CH-NH2 group acts as a hydrogen or electron donor and reduces a disulfide group.

The process whose specific outcome is the progression of the autonomic nervous system over time, from its formation to the mature structure. The autonomic nervous system is composed of neurons that are not under conscious control, and is comprised of two antagonistic components, the sympathetic and parasympathetic nervous systems. The autonomic nervous system regulates key functions including the activity of the cardiac (heart) muscle, smooth muscles (e.g. of the gut), and glands.
