- locus ceruleus formation
The process that gives rise to the locus ceruleus. This process pertains to the initial formation of a structure from unspecified parts. In mice, the locus ceruleus is a dense cluster of neurons within the dorsorostral pons. This nucleus is the major location of neurons that release norepinephrine throughout the brain, and is responsible for physiological responses to stress and panic.
- locus ceruleus maturation
A developmental process, independent of morphogenetic (shape) change, that is required for the locus ceruleus to attain its fully functional state. The locus ceruleus is a dense cluster of neurons within the dorsorostral pons. This nucleus is the major location of neurons that release norepinephrine throughout the brain, and is responsible for physiological responses to stress and panic.
- locus ceruleus development
The process whose specific outcome is the progression of the locus ceruleus over time, from its formation to the mature structure. The locus ceruleus is a dense cluster of neurons within the dorsorostral pons. This nucleus is the major location of neurons that release norepinephrine throughout the brain, and is responsible for physiological responses to stress and panic.
- locus ceruleus morphogenesis
The process in which the anatomical structure of the locus ceruleus is generated and organized. In mice, the locus ceruleus is a dense cluster of neurons within the dorsorostral pons. This nucleus is the major location of neurons that release norepinephrine throughout the brain, and is responsible for physiological responses to stress and panic.
- histone locus body
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.
- mating-type locus imprinting
A genomic imprinting process in which a stable single-strand DNA lesion triggers programmed gene conversion at the mating-type locus, thereby restricting mating-type interconversion to one of the two sister chromatids during DNA replication.
- gene conversion at mating-type locus
The conversion of the mating-type locus from one allele to another resulting from the recombinational repair of a site-specific double-strand break at the mating-type locus with information from a silent donor sequence. There is no reciprocal exchange of information because the mating-type locus copies information from the donor sequence and the donor sequence remains unchanged.
- replication fork arrest at tRNA locus
A process that impedes the progress of the DNA replication fork at natural replication fork pausing sites within the eukaryotic tRNA transcription unit.
- obsolete maintenance of imprinting at mating-type locus
OBSOLETE. Any process involved in preserving the structure of a stable single-strand DNA lesion that triggers programmed gene conversion at the mating-type locus, thereby restricting mating-type interconversion to one of the two sister chromatids during DNA replication.
- obsolete establishment of imprinting at mating-type locus
OBSOLETE. The initial formation of a stable single-strand DNA lesion that triggers programmed gene conversion at the mating-type locus, thereby restricting mating-type interconversion to one of the two sister chromatids during DNA replication.
